Prolog

Google Chrome Developers says:

The new WOFF 2.0 Web Font compression format offers a 30% average gain over WOFF 1.0 (up to 50%+ in some cases). WOFF 2.0 is available since Chrome 36 and Opera 23.

Some examples of file size differences: WOFF vs. WOFF2

TTF to WOFF2 converting

Embed WOFF2 in CSS (with WOFF fallback)

@font-face {
    font-family: MyFont;
    src:
        url('myfont.woff2') format('woff2'),
        url('myfont.woff') format('woff');
}
Base64 Data-URI

Of course you can use WOFF2 as a Base64 encoded string:

@font-face {
    font-family: MyFont;
    src:
        url('data:font/woff2;base64,...') format('woff2'),
        url('data:font/woff;base64,...') format('woff');
}

Good to know

  • Please no serverside GZIP compression for WOFF files, because WOFF already contains compressed data.
  • Think about the correct mime type for WOFF 2.0 files (Google uses font/woff2. W3C recommends application/font-woff2):
NGINX: WOFF2 mime type
types {
    application/font-woff2  woff2;
}
APACHE: WOFF2 mime type
AddType  application/font-woff2  .woff2

Browser Support
