Time to Say Goodbye to Google Fonts

Time to Say Goodbye to Google Fonts:


Optimised self-hosting fonts with preload:

The old performance argument

Google Fonts was designed to be distributed on a global CDN and reap the caching benefits from it. Users request fonts via said CDN. Chances are that they have downloaded the font resources at an earlier point already from a different site.

This was convincing enough to get many developers on board.

“[…] Our cross-site caching is designed so that you only need to load a font once, with any website, and we’ll use that same cached font on any other website that uses Google Fonts.”

Invalidating the old performance argument

Since Chrome v86, released October 2020, cross-site resources like fonts can’t be shared on the same CDN anymore. This is due to the partitioned browser cache (Safari has had this for years already).

In this Google post they explain what the partitioned browser cache is. It got only introduced to prevent a possible cross-site tracking mechanism.

Cache partitioning in other browsers

Safari really cares about privacy. It circumvented this very cross-site tracking attack since years already. Then finally comes Chrome. Other browsers that are based off Chromium, still need to signal or implement the feature.

✅ Chrome: since v86 (October 2020)
✅ Safari: since 2013
🚫 Firefox: planning to implement
🚫 Edge: most likely soon
🚫 Opera: most likely soon
🚫 Brave: most likely soon
🚫 Vivaldi: most likely soon


Google Fonts resources will be redownloaded for every website, regardless it being cached on the CDN. Self-host your fonts for better performance. The old performance argument is not valid anymore.
