Find the MIME (media) type for any file extension — or do the reverse and discover which extensions a MIME type covers. Search a built-in database of 150+ types, filter by category and copy values instantly. In your browser, free.

Everything runs in your browser from a built-in database — nothing is sent to the server.

Try:
Extension MIME type Category Description
No type matches your search.
Try a different extension or MIME type — for example .webp, video/mp4 or font.

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

  1. Type a file extension (.webp), a MIME type (video/mp4) or a description keyword into the search box.
  2. Narrow the list with the category filter — Web, Documents, Images, Audio, Video, Fonts, Archives, Data & config, Code or Other.
  3. Read the matching row: extension, MIME type, category and a short description of the format.
  4. Check the “also covers” note on entries whose MIME type maps to more than one extension.
  5. Use the copy buttons to grab the extension or the MIME type for your code or configuration.

Frequently asked questions

A two-part label — type/subtype, such as image/png or application/pdf — that declares a file’s format independently of its name. Browsers, mail clients and APIs rely on it to decide how to display, play or download content.

Search the file’s extension. The matching row gives the standard MIME type to put in the Content-Type header — for example .svg resolves to image/svg+xml and .json to application/json.

Yes. Type the MIME type itself — say audio/mpeg — and the entry shows which extension it belongs to, plus any additional extensions the same type covers.

Some formats have historical or alternative extensions for the same underlying type — JPEG images, for example, appear as both .jpg and .jpeg. Entries like these carry an explicit “this MIME type also covers” note.

Yes, completely free. The full database ships with the page and every search runs in your browser — nothing is sent to the server.
