About MIME Type Lookup

MIME Type Lookup is a searchable mapping between file extensions and MIME types (also called media types or content types) in both directions. Type an extension (`.pdf`, `webp`, `tar.gz`) and get the canonical type (`application/pdf`, `image/webp`, `application/gzip`); type a content type and get every extension that resolves to it. The data follows the IANA media-type registry, with widely-used unregistered types (like `image/x-icon`) included alongside the official ones.

Reach for it whenever you are setting `Content-Type` on a response, configuring a static-file server, or trying to figure out what extension a downloaded blob should have. Picking the right MIME type matters: the wrong one prevents browser previews, breaks `<img>` rendering, blocks PDF inlining, or causes downloads when an inline view was intended. HTTP Status Codes is the related reference for the other side of the response — what to put on the status line; this is for the `Content-Type` header.

Examples

Input

search: webp

Output

image/webp
— Extensions: .webp
— Registered with IANA, RFC 9649

Search by extension (`webp`, `.webp`) or by content type (`image/webp`). The result includes IANA registration and a link to the RFC.

Frequently asked questions

Why are some types prefixed with `application/x-` or `image/vnd.`?

`x-` was the original prefix for unregistered types; modern practice is to use `vnd.` (vendor) or just register the type with IANA. You will still see `x-` types in the wild — `application/x-tar`, `image/x-icon`, `application/x-www-form-urlencoded` — for historical reasons.

What MIME type should I serve a JSON file as?

`application/json`, per RFC 8259. Some legacy servers still serve `text/json` or `text/plain`, both of which work in a browser but are wrong; modern fetch APIs and JSON parsers expect `application/json` and may behave unpredictably with the wrong type.

Are there types for newer formats like AVIF, JXL, WebM?

Yes. `image/avif` (registered), `image/jxl` (provisional), `video/webm` (registered) — all in the lookup. New image and video formats are added to the IANA registry as they ship; the dataset here updates with each release.

What about CSS, JavaScript, and HTML?

`text/css` for CSS, `text/javascript` for JS (the IANA-preferred type as of 2022; `application/javascript` is still accepted), `text/html` for HTML. Browsers tolerate variation here, but matching the official type avoids subtle issues with CDN caching and CSP rules.
