Just look at MDN Web Docs   Here is a list of MIME types  associated by type of documents  ordered by their common extensions   Common MIME types

This post will explore various approaches of fetching MIME Type across various programming languages with their CONS in one-line description as header  So  use them accordingly and the one which works for you   For eg  the code below is especially helpful when user may supply either of  xls   xlsx or  xlsm and you don t want to write code testing extension and supplying MIME-type for each of them  Let the system do this job   Python 3  Using python-magic   gt  gt  gt  pip install python-magic  gt  gt  gt  import magic  gt  gt  gt  magic from file  Employee pdf   mime True   application pdf

implementation to resolve the type  Hence  if the file is known to the implementations then the content type is returned  However  if that doesn   t happen  a system-default file type detector is invoked     Resolve using first few characters of the input stream   Test public void getMIMEType from Extension        File file   new File  Employee xlsx        String mimeType   URLConnection

image png        It returns the matrix of MIME types used by all instances of URLConnection which then is used to resolve the input file type  However  this matrix of MIME types is very limited when it comes to URLConnection   By default  the class uses content-types properties file in JRE HOME lib  We can  however  extend it  by specifying a user-specific table using the content types user table

Interpret the Magic Number fetched using FileReader API  Final result looks something like this when one use javaScript to fetch the MimeType based on filestream  Open the embedded jsFiddle to see and understand this approach   Bonus  It s accessible for most of the MIME Types and also you can add custom Mime Types in the getMimetype function  Also  it has FULL SUPPORT for MS Office Files Mime Types     The steps to calculate mime type for a file in this example would be    The user selects a file  Take the first 4 bytes of the file using the slice method  Create a new FileReader instance Use the FileReader to read the 4 bytes you sliced out as an array buffer  Since the array buffer is just a generic way to represent a binary buffer we need to create a TypedArray  in this case an Uint8Array  With a TypedArray at our hands we can retrieve every byte and transform it to hexadecimal  by using toString 16    We now have a way to get the magic numbers from a file by reading the first four bytes  The final step is to map it to a real mime type    Browser Support  Above 95  overall and Close to 100  in all modern browsers        x000D   x000D  const uploads      x000D   x000D
