MIME Type Finder
Look up the MIME (media) type for any file extension, or find the extensions for a MIME type — and drop a file to see the type your browser reports. Runs entirely in your browser.

How it works
A MIME type (now called a media type) tells software what kind of data a file holds — e.g. image/png or application/json. Servers send it in the Content-Type header so browsers know how to handle a response. This tool matches against a built-in table of common types; the file-drop uses the browser's own File.type, which it infers from the extension.
