MIME types list & lookup

Find the right Content-Type for any file. Type an extension (or a whole file name) to get its MIME type instantly, or a MIME type to see which extensions use it.

How to look up a MIME type

1. Type an extension such as webp, a file name like report.xlsx, or a type like font/woff2.
2. The exact match appears at the top with a ready-to-paste Content-Type header; the table lists every related type.
3. Filter by category (images, fonts, documents…) to browse.

The MIME types every web server needs

A wrong type causes real bugs: scripts served as text/plain are blocked when X-Content-Type-Options: nosniff is set, ES modules must be a JavaScript type, .wasm needs application/wasm for streaming compilation, and SVGs served as application/octet-stream download instead of rendering.

Setting MIME types on your server

nginx

# /etc/nginx/mime.types is included by default; add missing ones:
types {
    application/manifest+json  webmanifest;
    image/avif                 avif;
}

Express

// express.static uses the mime-types package automatically.
res.type("application/json");          // set explicitly
res.set("Content-Type", "text/csv; charset=utf-8");

Apache (.htaccess)

AddType font/woff2 .woff2
AddType application/wasm .wasm

Anatomy of a MIME type

A media type is type/subtype plus optional parameters: text/html; charset=utf-8. The top-level types are text, image, audio, video, font, model, application and multipart. A +json or +xml suffix (e.g. application/ld+json) means the format is built on JSON or XML. vnd. subtypes are vendor-specific and x- subtypes are unregistered.
