A simple solution is to use flexbox  Define the container s CSS to    container      display  flex      justify-content  center      align-items  center      align-content  center      overflow  hidden         Any custom height        Adjust the contained image width to 100  and you should get a nice centered image in the container with the dimensions preserved

The simplest way to do this is by using object-fit    lt div class  container  gt     lt img src  path to image jpg  gt   lt  div gt    container     height  300px      container img    height  100     width  100     object-fit  cover      If you re using Bootstrap  just add the img-responsive class and change to   container img      object-fit  cover

As answered here  you can also use vh units instead of max-height  100  if it doesn t work on your browser  like Chrome    img       max-height  75vh

You can set the image as the background to a div  and then use the CSS background-size property   background-size  cover    It will  Scale the background image to be as large as possible so that the background area is completely covered by the background image  Some parts of the background image may not be in view within the background positioning area  -- W3Schools

Make it simple   Give the container a fixed height and then for the img tag inside it  set width and max-height    lt div style  height  250px  gt        lt img src       alt     style  width  100  max-height  100     gt   lt  div gt    The difference is that you set the width to be 100   not the max-width

Edit  Previous table-based image positioning had issues in Internet nbsp Explorer nbsp 11  max-height doesn t work in display table elements   I ve replaced it with inline based positioning which not only works fine in both Internet nbsp Explorer nbsp 7 and Internet nbsp Explorer nbsp 11  but it also requires less code     Here is my take on the subject  It ll only work if the container has a specified size  max-width and max-height don t seem to get along with containers that don t have concrete size   but I wrote the CSS content in a way that allows it to be reused  add picture-frame class and px125 size class to your existing container    In CSS    picture-frame       vertical-align  top      display  inline-block      text-align  center      picture-frame px125       width  125px      height  125px      line-height  125px      picture-frame img       margin-top  -4px     Inline images have a slight offset for some reason when positioned using vertical-align        max-width  100       max-height  100       display  inline-block      vertical-align  middle      border  0     Remove border on images enclosed in anchors in Internet Explorer        And in HTML    lt a href     class  picture-frame px125  gt       lt img src  http   i imgur com lesa2wS png   gt   lt  a gt     DEMO    x000D   x000D     Main style    x000D   x000D   picture-frame x000D    x000D      vertical-align  top  x000D      display  inline-block  x000D      text-align  center  x000D    x000D   x000D   picture-frame px32 x000D    x000D      width  32px  x000D      height  32px  x000D      line-height  32px  x000D    x000D   x000D   picture-frame px125 x000D    x000D      width  125px  x000D      height  125px  x000D      line-height  125px  x000D    x000D   x000D   picture-frame img x000D    x000D      margin-top  -4px     Inline images have a slight offset for some reason when positioned using vertical-align    x000D      max-width  100   x000D      max-height  100   x000D      display  inline-block  x000D      vertical-align  middle  x000D      border  0     Remove border on images enclosed in anchors in Internet Explorer    x000D    x000D   x000D     Extras    x000D   x000D   picture-frame x000D    x000D      padding  5px  x000D    x000D   x000D   frame x000D    x000D      border 1px solid black  x000D    x000D   lt p gt 32px lt  p gt  x000D   lt a href     class  picture-frame px32 frame  gt  x000D       lt img src  http   i imgur com lesa2wS png   gt  x000D   lt  a gt  x000D   lt a href     class  picture-frame px32 frame  gt  x000D       lt img src  http   i imgur com kFMJxdZ png   gt  x000D   lt  a gt  x000D   lt a href     class  picture-frame px32 frame  gt  x000D       lt img src  http   i imgur com BDabZj0 png   gt  x000D   lt  a gt  x000D   lt p gt 125px lt  p gt  x000D   lt a href     class  picture-frame px125 frame  gt  x000D       lt img src  http   i imgur com lesa2wS png   gt  x000D   lt  a gt  x000D   lt a href     class  picture-frame px125 frame  gt  x000D       lt img src  http   i imgur com kFMJxdZ png   gt  x000D   lt  a gt  x000D   lt a href     class  picture-frame px125 frame  gt  x000D       lt img src  http   i imgur com BDabZj0 png   gt  x000D   lt  a gt  x000D   x000D   x000D      Edit  Possible further improvement using JavaScript  upscaling images    function fixImage img        var  this     img       var parent    this closest   picture-frame        if   this width      parent width       this height      parent height            return       if   this width    gt   this height             this css  width   parent width      px        else          this css  height   parent height      px           picture-frame img visible   each function       if  this complete          fixImage this       else         this onload   function    fixImage this

I see that many people have suggested object-fit which is a good option  But if you want it to work in older browsers as well  there is another way of doing it easily    Its quite simple  The approach I took was to position the image inside the container with  absolute and then place it right at the centre using the combination    position  absolute  top  50   left  50   transform  translate -50   -50      Once it is in the centre  I give to the image       For vertical blocks  i e   where height is greater than width  height  100   width  auto      For Horizontal blocks  i e   where width is greater than height  height  auto  width  100     This makes the image get the effect of Object-fit cover      Here is a demonstration of the above logic   https   jsfiddle net furqan 694 s3xLe1gp   This logic works in all browsers

The accepted answer from Thorn007 doesn t work when the image is too small   To solve this  I added a scale factor  This way  it makes the image bigger and it fills the div container   Example    lt div style  width 400px  height 200px   gt     lt img src  pix jpg  style  max-width 100px  height 50px  transform scale 4   transform-origin left top     gt   lt  div gt    Notes    For WebKit you must add -webkit-transform scale 4   -webkit-transform-origin left top  in the style  With a scale factor of 4  you have max-width   400 4   100 and max-height   200 4   50 An alternate solution is to set max-width and max-height at 25   It s even simpler

Do not apply an explicit width or height to the image tag  Instead  give it   max-width 100   max-height 100     Also  height  auto  if you want to specify a width only   Example  http   jsfiddle net xwrvxser 1    x000D   x000D  img   x000D      max-width  100   x000D      max-height  100   x000D    x000D   x000D   portrait   x000D      height  80px  x000D      width  30px  x000D    x000D   x000D   landscape   x000D      height  30px  x000D      width  80px  x000D    x000D   x000D   square   x000D      height  75px  x000D      width  75px  x000D    x000D  Portrait Div x000D   lt div class  portrait  gt  x000D       lt img src  http   i stack imgur com xkF9Q jpg  gt  x000D   lt  div gt  x000D   x000D  Landscape Div x000D   lt div class  landscape  gt  x000D       lt img src  http   i stack imgur com xkF9Q jpg  gt  x000D   lt  div gt  x000D   x000D  Square Div x000D   lt div class  square  gt  x000D       lt img src  http   i stack imgur com xkF9Q jpg  gt  x000D   lt  div gt  x000D   x000D   x000D

Give the height and width you need for your image to the div that contains the  lt img  tag  Don t forget to give the height width in the proper style tag   In the  lt img  tag  give the max-height and max-width as 100     lt div style  height 750px  width 700px   gt       lt img alt  That Image  style  max-height 100   max-width 100    src    gt   lt  div gt    You can add the details in the appropriate classes after you get it right

A beautiful hack   You have two ways of making the image responsive         When an image is a background image        container      width  300px      height  300px      background-image  url http   images fonearena com blog wp-content uploads 2013 11 Lenovo-p780-camera-sample-10 jpg       background-size  cover      background-repeat  no-repeat      background-position  center      lt div id  container  gt  lt div gt    Run it here   But one should use img tag to put images as it is better than background-image in terms of SEO as you can write keyword in the alt of the img tag  So here is you can make the image responsive         When image is in img tag        container      max-width  400px      overflow  hidden    img      width  100       object-fit  contain      lt div id  container  gt      lt img src  http   images fonearena com blog wp-content uploads 2013 11 Lenovo-p780-camera-sample-10 jpg  alt  your keyword   gt   lt div gt    Run it here

The solution is easy with a bit of maths     Just put the image in a div and then in the HTML file where you specify the image  Set the width and height values in percentages using the pixel values of the image to calculate the exact ratio of width to height   For example  say you have an image that has a width of 200 pixels and a height of 160 pixels  You can safely say that the width value will be 100   because it is the larger value  To then calculate the height value you simply divide the height by the width which gives the percentage value of 80   In the code it will look something like this      lt div class  image holder div  gt       lt img src  some pic png  width  100   height  80   gt   lt  div gt

A simple solution  4-step fix    that seems to work for me  is below  The example uses the width to determine the overall size  but you can also flip it to use the height instead    Apply CSS styling to the image container  for example   lt img   Set the width property to the dimension you want   For dimensions  use   for relative size  or autoscaling  based on image container or display  Use px  or other  for a static  or set dimension  Set the height property to automatically adjust  based on the width ENJOY    For example    lt img style  width 100   height auto       src  https   googledrive com host 0BwDx0R31u6sYY1hPWnZrencxb1k thanksgiving png    gt

Currently there is no way to do this correctly in a deterministic way  with fixed-size images such as JPEGs or PNG files   To resize an image proportionally  you have to set either the height or width to  100    but not both  If you set both to  100    your image will be stretched   Choosing whether to do height or width depends on your image and container dimensions    If your image and container are both  portrait shaped  or both  landscape shaped   taller than they are wide  or wider than they are tall  respectively   then it doesn t matter which of height or width are   100   If your image is portrait  and your container is landscape  you must set height  100   on the image  If your image is landscape  and your container is portrait  you must set width  100   on the image    If your image is an SVG  which is a variable-sized vector image format  you can have the expansion to fit the container happen automatically   You just have to ensure that the SVG file has none of these properties set in the  lt svg gt  tag   height width viewbox   Most vector drawing programs out there will set these properties when exporting an SVG file  so you will have to manually edit your file every time you export  or write a script to do it

I have much better solution without need of any JavaScript  It is fully responsive  and I use it a lot  You often need to fit an image of any aspect ratio to a container element with a specified aspect ratio  And having whole this thing fully responsive is a must    x000D   x000D     For this demo only    x000D   container   x000D    max-width  300px  x000D    margin  0 auto  x000D    x000D   img-frame   x000D    box-shadow  3px 3px 6px rgba 0  0  0   15   x000D    background   ee0  x000D    margin  20px auto  x000D    x000D   x000D     This is for responsive container with specified aspect ratio    x000D   aspect-ratio   x000D    position  relative  x000D    x000D   aspect-ratio-1-1   x000D    padding-bottom  100   x000D    x000D   aspect-ratio-4-3   x000D    padding-bottom  75   x000D    x000D   aspect-ratio-16-9   x000D    padding-bottom  56 25   x000D    x000D   x000D     This is the key part - position and fit the image to the container    x000D   fit-img   x000D    position  absolute  x000D    top  0  x000D    right  0  x000D    bottom  0  x000D    left  0  x000D    margin  auto  x000D    max-width  80   x000D    max-height  90  x000D    x000D   fit-img-bottom   x000D    top  auto  x000D    x000D   fit-img-tight   x000D    max-width  100   x000D    max-height  100  x000D    x000D   lt div class  container  gt  x000D   x000D     lt div class  aspect-ratio aspect-ratio-1-1 img-frame  gt  x000D       lt img src    placehold it 400x300  class  fit-img  alt  sample  gt  x000D     lt  div gt  x000D   x000D     lt div class  aspect-ratio aspect-ratio-4-3 img-frame  gt  x000D       lt img src    placehold it 400x300  class  fit-img fit-img-tight  alt  sample  gt  x000D     lt  div gt  x000D   x000D     lt div class  aspect-ratio aspect-ratio-16-9 img-frame  gt  x000D       lt img src    placehold it 400x400  class  fit-img  alt  sample  gt  x000D     lt  div gt  x000D   x000D     x000D     lt div class  aspect-ratio aspect-ratio-16-9 img-frame  gt  x000D       lt img src    placehold it 300x400  class  fit-img fit-img-bottom  alt  sample  gt  x000D     lt  div gt  x000D     x000D   lt  div gt  x000D   x000D   x000D    You can set max-width and max height independently  the image will respect the smallest one  depending on the values and aspect ratio of the image   You can also set image to be aligned as you want  for example  for a product picture on an infinite white background you can position it to center bottom easily

I centered and scaled proportionally an image inside a hyperlink both horizontally and vertically this way    link       border  1px solid blue      display  table-cell      height  100px      vertical-align  middle      width  100px     link img       border  1px solid red      display  block      margin-left  auto      margin-right  auto      max-height  60px      max-width  60px      It was tested in Internet nbsp Explorer  Firefox  and Safari   More information about centering is here

This solution doesn t stretch the image and fills the whole container  but it cuts some of the image   HTML     lt div gt  lt img src   images image png  gt  lt  div gt    CSS   div       width  100       height  10em      overflow  hidden   img       min-width  100       min-height  100
