To extend the answer a little bit to support local images  just replace FILE PATH PLACEHOLDER to your image path and check it out     lt p align  center  gt     lt img src  FILE PATH PLACEHOLDER  gt   lt  p gt

I ve been looking at the markdown syntax used in github        I can t figure out how to center an image   TL DR  No you can t by only relying on Markdown syntax  Markdown doesn t care with positioning   Note  Some markdown processors support inclusion of HTML  as rightfully pointed out by  waldyr ar   and in the GitHub case you may fallback to something like  lt div style  text-align center  gt  lt img src         gt  lt  div gt   Beware that there s no guarantee the image will be centered if your repository is forked in a different hosting environment  Codeplex  BitBucket       or if the document isn t read through a browser  Sublime Text Markdown preview  MarkdownPad  VisualStudio Web Essentials Markdown preview         Note 2  Keep in mind that even within the GitHub website  the way markdown is rendered is not uniform  The wiki  for instance  won t allow such css positional trickery   Unabridged version  The Markdown syntax doesn t provide one with the ability to control the position of an image   In fact  it would be borderline against the Markdown philosophy to allow such formatting  as stated in the  Philosophy  section      A Markdown-formatted document should be publishable as-is  as plain text  without looking like it   s been marked up with tags or formatting instructions      Markdown files are rendered by github com website through the use of the Ruby Redcarpet  library   Redcarpet exposes some extensions  such as strikethrough  for instance  which are not part of standard Markdown syntax and provide additional  features   However  no supported extension allow you to center an image

My way to resolve the problem with image positioning was to use the HTML attributes:

![Image](Image.svg){ width="800" height="600" style="display: block; margin: 0 auto" }

The image was resized and centered properly, at least in my local VS markdown renderer.

Then, I have pushed changes to repo and unfortunately realized that it is not working for GitHub README.md file. Nevertheless I will left this answer as it might help someone else.

So finally, I have ended up using good old HTML tag instead:

<img src="Image.svg" alt="Image" width="800" height="600" style="display: block; margin: 0 auto" />

But guess what? Some JS method replaced my style attribute! I have even tried class attribute and with the same result!

Then I have found following gist page where even more old-school HTML was used:

<p align="center">
    <img src="Image.svg" alt="Image" width="800" height="600" />
</p>

This one is working fine however, I would like to leave it without further comments...

This is from Github s support   Hey Waldyr  Markdown doesn t allow you to tweak alignment directly  see docs here  http   daringfireball net projects markdown syntax img   but you can just use a raw HTML  img  tag and do the alignment with inline css  Cheers   So it is possible to align images  You just have to use inline css to solve the problem  You can take an example from my github repo  At the bottom of README md there is a centered aligned image  For simplicity you can just do as follows   lt p align  quot center quot  gt     lt img src  quot http   some place com image png quot    gt   lt  p gt   Although  as nulltoken said  it would be borderline against the Markdown philosophy   This code from my readme   lt p align  quot center quot  gt     lt img src  quot https   github com waldyr Sublime-Installer blob master sublime text png raw true quot  alt  quot Sublime s custom image quot   gt   lt  p gt   Produces this image output  except centered when viewed on GitHub   lt p align  quot center quot  gt     lt img src  quot https   github com waldyr Sublime-Installer blob master sublime text png raw true quot  alt  quot Sublime s custom image quot   gt   lt  p gt

A  pure  markdown approach that can handle this is adding the image to a table and then centering the cell       Image  img png       --       It should produce HTML similar to this    lt table gt       lt thead gt           lt tr gt               lt th style  text-align center   gt  lt img src  img png  alt  Image  gt  lt  th gt           lt  tr gt       lt  thead gt       lt tbody gt       lt  tbody gt   lt  table gt

TLDR  Just jump straight down to look at the 4 examples  1 1  1 2  1 3  and 1 4  in the section below called  quot 1  Centering and aligning images in GitHub readmes using the deprecated HTML align attribute quot   Also  view actual examples of this on GitHub in a couple readme markdown files in my repositories here   https   github com ElectricRCAircraftGuy eRCaGuy hello world blob master markdown github readme center and align images md and https   github com ElectricRCAircraftGuy eRCaGuy hello world 3-markdown      Background on how to center and align images in markdown  So  it turns out that GitHub explicitly blocks filters out all attempts at editing any form of CSS  Cascading Style Sheets  styles  including external  internal  and inline  inside GitHub   md markdown files  such as readmes  See here  emphasis added    Custom css file for readme md in a Github repo  GitHub does not allow for CSS to affect README md files through CSS for security reasons      https   github community t github-flavored-markdown-doesnt-render-css-styles-inside-a-html-block 126258 2 u electricrcaircraftguy  Unfortunately you cannot use CSS in GitHub markdown as it is a part of the sanitization process   The HTML is sanitized  aggressively removing things that could harm you and your kin   such as script tags  inline-styles  and class or id attributes   source  https   github com github markup    So  that means to center or align images in GitHub readmes  your only solution is to use the deprecated HTML align attribute  that happens to still function   as this answer shows  I should also point out that although that solution does indeed work  it is causing a lot of confusion for that answer to claim to use inline css to solve the problem  since  like  Poikilos points out in the comments  that answer has no CSS in it whatsoever  Rather  the align  quot center quot  part of the  lt p gt  element is a deprecated HTML attribute  that happens to still function  and is NOT CSS  All CSS  whether external  internal  or inline is banned from GitHub readmes and explicitly removed  as indicated through trial-and-error and in the two references above  This leads me to split my answer into two answers here    quot Centering and aligning images in GitHub readmes using the deprecated HTML align attribute quot   and  quot Centering and aligning images using modern CSS in any markdown document where you also have control over CSS styles quot    Option 2 only works in places where you have full control over CSS styles  such as in a custom GitHub Pages website you make maybe   1  Centering and aligning images in GitHub readmes using the deprecated HTML align attribute  This works in any GitHub   md markdown file  such as a GitHub readme md file  It relies on the deprecated HTML align attribute  but still works fine  You can see a full demo of this in an actual GitHub readme in my eRCaGuy hello world repo here  https   github com ElectricRCAircraftGuy eRCaGuy hello world blob master markdown github readme center and align images md  Notes   Be sure to set width  quot 100  quot  inside each of your  lt p gt  paragraph elements below  or else the entire paragraph tries to allow word wrap around it  causing weird and less-predicable effects  To resize your image  simly set width  quot 30  quot   or whatever percent you d like between 0  and 100   to get the desired effect  This is much easier than trying to set a pixel size  such as width  quot 200 quot  height  quot 150 quot   as using a width percent automatically adjusts to your viewer s screen and to the page display width  and it automatically resizes the image as you resize your browser window as well  It also avoids skewing the image into unnatural proportions  It s a great feature  Options for the  deprecated  HTML align attribute include left  center  right  and justify   1 1  Align images left  right  or centered  with NO WORD WRAP  This    Align left     lt p align  quot left quot  width  quot 100  quot  gt       lt img width  quot 33  quot  src  quot https   i stack imgur com RJj4x png quot  gt    lt  p gt     Align center     lt p align  quot center quot  width

  lt img width  quot 33  quot  src  quot https   i stack imgur com RJj4x png quot  gt    lt  p gt   Produces this   If you d like to set the text itself to left  center  or right  you can include the text inside the  lt p gt  element as well  as regular HTML  like this   lt p align  quot right quot  width  quot 100  quot  gt      This text is also aligned to the right  lt br gt       lt img width

alignment and vertical spacing formatting you may be trying to maintain  This  33  width each   possibly  a little too wide to fit all 3 images side-by-side  depending on your markdown viewer    lt p

 quot  src  quot https   i stack imgur com RJj4x png quot  gt    lt  p gt   Produces this   I am aligning all paragraph  lt p gt  elements above to the center  but you can also align left or right  as shown in previous examples  to force the row of images to get aligned that way too  Example  This  Align the whole row of images to the right this time   lt p align  quot right quot  width  quot 100  quot  gt       lt img width  quot 25  quot  src  quot https   i stack imgur com RJj4x png quot  gt        lt img width  quot 25  quot  src  quot https   i stack imgur com RJj4x png quot  gt        lt img width  quot 25  quot  src  quot https   i stack imgur com RJj4x png quot  gt    lt  p gt   Produces this  aligning the whole row of images according to the align attribute set above  or to the right in this case   Generally  center is preferred  as done in the examples above   1 4  Use a markdown table to improve vertical spacing of odd-sized odd-shaped images  Sometimes  with odd-sized or different-shaped images  using just the  quot row of images quot  methods above produces slightly awkward-looking results  This code produces two rows of images which have good horizontal spacing  but bad vertical spacing  This code   lt p align  quot center quot  width  quot 100  quot  gt       lt img width  quot 32  quot  src  quot photos pranksta1 jpg quot  gt        lt img width  quot 32  quot  src  quot photos pranksta2 jpg quot  gt        lt img width  quot 32  quot  src  quot photos pranksta3 jpg quot  gt    lt  p gt   lt p align  quot center quot  width  quot 100  quot  gt       lt img width  quot 32  quot  src  quot photos pranksta4 jpg quot  gt        lt img width  quot 32  quot  src  quot photos pranksta5 jpg quot  gt        lt img width  quot 32  quot  src  quot photos pranksta6 jpg quot  gt    lt  p gt   Produces this  since the last image in row 1   quot pranksta3 jpg quot   is a very tall image with 2x the height as the other images   So  placing those two rows of images inside a markdown table forces nice-looking vertical spacing  Notice in the markdown table below that each image is set to have an HTML width attribute set to 100   This is because it is relative to the table cell the image sits in  NOT relative to the page column width anymore  Since we want each image to fill the entire width of each cell  we set their widths all to width  quot 100  quot   This markdown table with images in it                                                                                                                                                     ----------------------------------------------- ----------------------------------------------- -----------------------------------------------     lt img width  quot 100  quot  src  quot photos pranksta1 jpg quot  gt     lt img width  quot 100  quot  src  quot photos pranksta2 jpg quot  gt     lt img width  quot 100  quot  src  quot photos pranksta3 jpg quot  gt       lt img width  quot 100  quot  src  quot photos pranksta4 jpg quot  gt     lt img width  quot 100  quot  src  quot photos pranksta5 jpg quot  gt     lt img width  quot 100  quot  src  quot photos pranksta6 jpg quot  gt     Produces this  which looks much nicer and more well-spaced in my opinion  since vertical spacing is also centered for each row of images    2  Centering and aligning images using modern CSS in any markdown document where you also have control over CSS styles  This works in any markdown file  such as a GitHub Pages website maybe   where you do have full control over CSS styles  This does NOT work in any GitHub   md markdown file  such as a readme md  therefore  because GitHub expliclty scans for and disables all custom CSS styling you attempt to use  See above  TLDR  Use this HTML CSS to add and center an image and set its size to 60  of the screen space width inside your markdown file  which is usually a good starting value   lt img src  quot https   i stack imgur com RJj4x png quot        style  quot display block float none margin-left auto margin-right auto width 60  quot  gt    Change the width CSS value to whatever percent you want  or remove it altogether to use the markdown default size  which I think is 100  of the screen width if the image is larger than the screen  or it is the actual image width otherwise  Done  Or  keep reading for a lot more information  Here are various HTML and CSS options which work perfectly inside markdown files  so long as CSS is not explicitly forbidden  1  Center and configure  resize  ALL images in your markdown file  Just copy and paste this to the top of your markdown file to center and resize all images in the file  then just insert any images you want with normal markdown syntax    lt style gt  img       display block       float none       margin-left auto      margin-right auto      width 60      lt  style gt    Or  here is the same code as above but with detailed HTML and CSS comments to explain exactly what is going on   lt  --  This is an HTML comment   Copy and paste this entire HTML   lt style gt     lt  style gt   element  block  to the top of your markdown file -- gt   lt style gt      This is a CSS comment   The below  img  style sets the default CSS styling for all images hereafter in this markdown file     img          Default display value is  inline-block   Set it to  block  to prevent surrounding text from     wrapping around the image  Instead   block  format will force the text to be above or below the     image  but never to the sides         display block          Common float options are  left    right   and  none   Set to  none  to override any previous     settings which might have been  left  or  right    left  causes the image to be to the left      with text wrapped to the right of the image  and  right  causes the image to be to the right      with text wrapped to its left  so long as  display inline-block  is also used         float none          Set both the left and right margins to  auto  to cause the image to be centered         margin-left auto      margin-right auto         You may also set the size of the image  in percent of width of the screen on which the image     is being viewed  for example  A good starting point is 60   It will auto-scale and auto-size     the image no matter what screen or device it is being viewed on  maintaining proporptions and      not distorting it         width 60          You may optionally force a fixed size  or intentionally skew distort an image by also      setting the height  Values for  width  and  height  are commonly set in either percent          or pixels  px   Ex   width 100    or  height 600px              height 400px        lt  style gt    Now  whether you insert an image using markdown      https   i stack imgur com RJj4x png   Or HTML in your markdown file   lt img src  quot https   i stack imgur com RJj4x png quot  gt       it will be automatically centered and sized to 60  of the screenview width  as described in the comments within the HTML and CSS above   Of course the 60  size is really easily changeable too  and I present simple ways below to do it on an image-by-image basis as well   2  Center and configure images on a case-by-case basis  one at a time  Whether or not you have copied and pasted the above  lt style gt  block into the top of your markdown file  this will also work  as it overrides and takes precedence over any file-scope style settings you may have set above   lt img src  quot https   i stack imgur com RJj4x png quot  style  quot display block float none margin-left auto margin-right auto width 60  quot  gt    You can also format it on multiple lines  like this  and it will still work   lt img src  quot https   i stack imgur com RJj4x png quot        alt  quot this is an optional description of the image to help the blind and show up in case the            image won t load quot        style  quot display block     override the default display setting of  inline-block                  float none     override any prior settings of  left  or  right                     set both the left and right margins to  auto  to center the image                margin-left auto               margin-right auto              width 60      optionally resize the image to a screen percentage width if you want too                 quot  gt    3  In addition to all of the above  you can also create CSS style classes to help stylize individual images  Add this whole thing to the top of your markdown file   lt style gt      By default  make all images center-aligned  and 60  of the width  of the screen in size    img       display block       float none       margin-left auto      margin-right auto      width 60         Create a CSS class to style images to left-align  or  quot float left quot      leftAlign       display inline-block      float left         provide a 15 pixel gap between the image and the text to its right        margin-right 15px         Create a CSS class to style images to right-align  or  quot float right quot      rightAlign       display inline-block      float right         provide a 15 pixel gap between the image and the text to its left        margin-left 15px      lt  style gt    Now  your img CSS block has set the default setting for images to be centered and 60  of the width of the screen space in size  but you can use the leftAlign and rightAlign CSS classes to override those settings on an image-by-image basis  For example  this image will be center-aligned and 60  in size  the default I set above    lt img src  quot https   i stack imgur com RJj4x png quot  gt    This image will be left-aligned  however  with text wrapping to its right  using the leftAlign CSS class we just created above   lt img src  quot https   i stack imgur com RJj4x png quot  class  quot leftAlign quot  gt   It might look like this   You can still override any of its CSS properties via the style attribute  however  such as width  like this   lt img src  quot https   i stack imgur com RJj4x png quot  class  quot leftAlign quot  style  quot width 20  quot  gt   And now you ll get this   4  Create 3 CSS classes  but don t change the img markdown defaults Another option to what we just showed above  where we modified the default img property value settings and created 2 classes  is to just leave all the default markdown img properties alone  but create 3 custom CSS classes  like this   lt style gt      Create a CSS class to style images to center-align     centerAlign       display block      float none         Set both the left and right margins to  auto  to cause the image to be centered         margin-left auto      margin-right auto      width 60         Create a CSS class to style images to left-align  or  quot float left quot      leftAlign       display inline-block      float left         provide a 15 pixel gap between the image and the text to its right        margin-right 15px       width 60         Create a CSS class to style images to right-align  or  quot float right quot      rightAlign       display inline-block      float right         provide a 15 pixel gap between the

centerAlign quot  style  quot width 20  quot  gt   Notice how I manually set the width property using the CSS style attribute above  but if I had something more complicated I wanted to do  I could also create some additional classes like this  adding them inside the  lt style gt     lt  style gt  block above     custom CSS class to set a predefined  quot small quot  size for an image     small       width 20          set any other properties  as desired  inside this class too       Now you can assign multiple classes to the same object  like this  Simply  separate class names by a space  NOT a comma  11   In the event of conflicting settings  I believe whichever setting comes last will be the one that takes effect  overriding any previously-set settings  This should also be the case in the event you set the same CSS properties multiple times in the same CSS class or inside the same HTML style attribute   lt img src  quot https   i stack imgur com RJj4x png quot  class  quot

above  all 3 of the CSS align classes set the image width to 60   Therefore  this common setting can be set all at once like this if you wish  then you can set the specific settings for each class afterwards   lt style gt      set common properties for multiple CSS classes all at once     centerAlign   leftAlign   rightAlign       width 60         Now set the specific properties for each class

As far as I m concerned  anything which can be written in a markdown document and get the desired result is all we are after  not some  quot pure markdown quot  syntax  In C and C    the compiler compiles down to assembly code  and the assembly is then assembled down to binary  Sometimes  however  you need the low-level control that only assembly can provide  and so you can write inline assembly right inside of a C or C   source file  Assembly is the  quot lower level quot  language and it can be written right inside C and C    So it is with markdown  Markdown is the high-level language which is interpreted down to HTML and CSS  However  where we need extra control  we can just  quot inline quot  the lower-level HTML and CSS right inside of our markdown file  and it will still be interpreted correctly  In a sense  therefore  HTML and CSS are valid  quot markdown quot  syntax  So  to center an image in markdown  use HTML and CSS  2  Standard image insertion in markdown

You can also resize the image to the desired width and height. For example:

<p align="center">
  <img src="https://anyserver.com/image.png" width="750px" height="300px"/></p>

To add a centered caption to the image, just one more line:

<p align="center">This is a centered caption for the image<p align="center">

Fortunately, this works both for README.md and the GitHub Wiki pages.

Alternatively  if you have control of the css  you could get clever with url parameters and css   Markdown     A cute kitten  http   placekitten com 200 300 style centerme    And CSS   img src   centerme       display block    margin  0 auto      You could create a variety of styling options this way and still keep the markdown clean of extra code  Of course you have no control over what happens if someone else uses the markdown somewhere else but thats a general styling issue with all markdown documents one shares

if modifying the image is not a problem for you  and if you know the approximate width of the container that will display your markdown  and if your image is used in one place only  for example a README used only in GitHub   then you can edit your image in an image editor and pad it equally on both sides  Before padding   After padding   Original image  width   250px    Padded image  width   660px

Background on how to center and align images in markdown:

1. Centering and aligning images in GitHub readmes using the deprecated HTML `align` attribute:

1.1. Align images left, right, or centered, with NO WORD WRAP:

1.2. Align images left, right, or centered, WITH word wrap:

1.3. Align images side-by-side:

1.4. Use a markdown table to improve vertical spacing of odd-sized/odd-shaped images:

2. Centering and aligning images using modern CSS in any markdown document where you also have control over CSS styles:

TLDR;

Here are various HTML and CSS options which work perfectly inside markdown files, so long as CSS is not explicitly forbidden:

1. Center and configure (resize) ALL images in your markdown file:

2. Center and configure images on a case-by-case basis, one at a time:

3. In addition to all of the above, you can also create CSS style classes to help stylize individual images:

4. Create 3 CSS classes, but don't change the `img` markdown defaults

5. Consolidate Common Settings in CSS Classes:
