Find the Content-Type for a file extension, or search by MIME type. Live filter.
A MIME type (or media type / Content-Type) tells browsers and servers what kind of file something is, like text/html or image/png. Servers send it in the Content-Type header so the client knows how to handle the data.
Type the extension (with or without the dot) in the search box. You can also search the other way, by typing part of a MIME type like 'video' or 'json' to see all matching extensions.
If a server sends the wrong Content-Type, browsers may refuse to run a script, download a file instead of displaying it, or block it entirely. Matching the right type avoids those issues.
