Good to know

  • The font/ top-level type was registered by RFC 8081 in 2017; older configs use application/x-font-ttf.
  • Uncompressed, so enable gzip or Brotli if you serve TTF files.

Serve .ttf files with the right type

The response header to send:

Content-Type: font/ttf

Most servers pick the type from the file extension. If yours sends the wrong one, map it explicitly:

nginx (inside the types block in mime.types)
font/ttf ttf;
Apache (.htaccess or server config)
AddType font/ttf .ttf
Express
res.set("Content-Type", "font/ttf");
Python
import mimetypes

mimetypes.add_type("font/ttf", ".ttf")
HTML file input
<input type="file" accept=".ttf,font/ttf">

Check it

See what a server sends for a file, and what type a local file really is by its contents:

curl -sI https://example.com/file.ttf | grep -i '^content-type:'
file --mime-type file.ttf

Frequently asked questions

What is the MIME type for .ttf files?

font/ttf. You may also see application/x-font-ttf, application/font-sfnt, but font/ttf is the one to send.

What Content-Type header should a .ttf file be served with?

Content-Type: font/ttf. It compresses well, so let the server apply gzip or Brotli.

How can I tell if a file is really a .ttf?

Check its bytes rather than the extension: TTF files start with 00 01 00 00. On the command line, file --mime-type name.ttf does this for you.
