About MIME Type List
The MIME Type List is a searchable database of more than 150 MIME (media) types matched to their file extensions. Type an extension like .pdf, a MIME type like image/png or a plain description, and the matching entries appear instantly — filterable by category, from web files and documents to images, audio, video, fonts, archives, data formats and code.
MIME types are what servers, browsers and APIs use to declare what a file actually is: the Content-Type header of an HTTP response, the accept attribute of an upload field, or the type whitelist of an upload validator. Developers look them up whenever a browser downloads a file instead of displaying it, or an upload is rejected for the wrong declared type.
The lookup works in both directions. Search by extension to get the correct MIME type, or search by MIME type to see every extension it covers — entries that map to several extensions say so explicitly. Copy either value with one click; the whole reference runs from a built-in database in your browser.
How to use MIME Type List
- Type a file extension (.webp), a MIME type (video/mp4) or a description keyword into the search box.
- Narrow the list with the category filter — Web, Documents, Images, Audio, Video, Fonts, Archives, Data & config, Code or Other.
- Read the matching row: extension, MIME type, category and a short description of the format.
- Check the “also covers” note on entries whose MIME type maps to more than one extension.
- Use the copy buttons to grab the extension or the MIME type for your code or configuration.
