How teams usually encounter it

This page maps the media type to the file extensions and delivery behaviors developers usually care about: browser parsing, upload validation, cache correctness, and asset handling.

Compression signal

font/woff often benefits from gzip or Brotli in HTTP delivery because the payload is text-like or structurally repetitive.

Server config snippets

Use these when a server is missing the right extension-to-MIME mapping or you want the expected header to survive a proxy, CDN, or custom asset bucket setup.

Nginx
types {
  font/woff woff;
}
Apache
AddType font/woff .woff

Signature note

This MIME type does not include a magic-byte sample here because the signature is either format-dependent or not reliable enough to present as a debugging shortcut.

Operational shortcut

If a browser downloads this asset instead of rendering it correctly, check the response header first, then verify the extension mapping on your origin and edge cache. .woff is the fastest sanity check for teammates reviewing the file outside the app.
