Find out our dedicated font optimizations

font optimizations

In our article Webperf: Optimizing font loading, we demonstrated the impact that font loading can have on site performance.
In particular, we noticed that the Speed Index and the Start Render fell by an average of 5 to 10% when fonts were not loaded.

When it comes to font optimization, the tool that’s generally recommended is Font-Squirrel. It’s a fantastic tool, but it does have the drawback of being manual. So we decided to retain its best features to develop our own automatic font optimization engine.
Here, we’ll cover:

  1. generating fonts in WOFF2 format
  2. automatically updating the CSS @font-face declaration
  3. adding the font-display property
  4. minifying fonts via the subsetting technique
  5. font autohinting for better visual rendering in Windows
  6. optimizing loading of Google Fonts
