MIME Types Reference
Find the correct MIME type (content type) for a file extension in one searchable list. Setting the wrong Content-Type header can make a browser download a file instead of displaying it, break an upload validation, or cause a font or image to fail silently, so getting it right matters. This reference maps common extensions to their standard MIME type strings across text, images, audio, video, fonts, archives and application formats, and you can filter it instantly by extension or type. Type an extension like svg or a keyword like json to jump straight to the value you need for a header, a server config or an upload allowlist. The whole table is bundled into the page, so lookups are instant and fully offline.
How to use MIME Types Reference
- Type a file extension or keyword.
- Read the matching content-type value.
- Copy it into your Content-Type header.
