About this MIME Type Lookup

Find MIME types, file extensions, and content type information.

Search either direction: type an extension such as .webp to find its media type, or a media type such as image/ to list everything in that family. Narrow by category, or export the current list as JSON or CSV. These are the values a server sends in the Content-Type header.

All 1014 media types

Every type in the lookup above, grouped by top-level type, with the file extensions mapped to it. Compiled from the IANA media types registry together with the mappings nginx and Apache ship, so it covers what web servers actually send as well as what is registered.

FAQ

Can I search by MIME type to find matching extensions (reverse lookup)?

Yes — search works both directions. Type an extension like .webp to find its media type, or type a media type or family like image/ to list every matching entry.

How many file types does this database cover?

1,018 media types — every entry in the mime-db database that carries a file extension, plus anything nginx or Apache ship in their own mime.types files. It is deliberately not a mirror of the full IANA registry: 1,329 of IANA's 2,256 registrations are vendor-specific vnd.* types, and because this tool is reached through a file extension, a type with no extension has no route into it. A type that is out of scope simply reports no match — it never produces a confidently wrong answer.

Do .jpg and .jpeg (or other synonym extensions) share the same MIME type?

Yes — extensions that describe the same underlying format map to one entry. .jpg, .jpeg, and .jpe are all image/jpeg; .txt and .text are both text/plain. Look up any of them and you land on the same result.

Why does the wrong MIME type break my upload or preview?

Browsers and servers use Content-Type to decide how to render or handle a file — a mismatch can cause downloads instead of previews, or rejected uploads.

What MIME type should I use for a file with an unknown or missing extension?

application/octet-stream — the generic fallback for arbitrary binary data when the format can't be determined. Browsers typically treat it as something to download rather than render inline.

Should SVG be served as image/svg+xml or text/plain?

image/svg+xml — serving it as text/plain prevents it rendering as an image.

Why does .js map to application/javascript instead of text/javascript?

RFC 9239 updated the formally preferred type to text/javascript in 2021, and this tool lists it as an alias — but application/javascript is still shown as the primary entry here since it remains the more commonly seen value in the wild.

Is my lookup sent to a server?

No, entirely client-side.
