Local Open Sans contains copies of Open Sans fonts that WordPress loads from Google Fonts. The plugin deregisters the admin style that loads these fonts remotely and replaces it with a stylesheet that loads local copies of the same fonts.
Recommended for development when “fonts.googleapis.com” is adding time to admin pageloads. Not recommended for production (live sites) because it is almost always faster for your visitors to load fonts from Google or to use cached copies.

Local Open Sans

Replace Open Sans with a local copy to speed up admin testing and development.

This plugin stops loading of fonts from Google Fonts used by WordPress core, Gutenberg plugin, bundled themes (Twenty Twelve, Twenty Thirteen, Twenty Fourteen, Twenty Fifteen, Twenty Sixteen, Twenty Seventeen), and most other themes. If theme or plugin (whose name is not listed here) uses fonts from Google Fonts, those fonts still might be loaded if that theme or plugin loads fonts from Google in a way that is incompatible with this plugin.
Reasons for not using Google Fonts might be privacy and security, local development or production, blocking of Google’s servers, characters not supported by font, performance.
Disable Google Fonts is a very lightweight, it has no settings, just activate it and it works immediately.

Disable Google Fonts

I need to use a local copy of WP with no internet access. This plugin stops WP from trying to download fonts from google and then popping up error messages, which makes things so much easier to use.

Just works

So I was demonstrating my kiosk appliance with my access point appliance + LEMP stack. I installed WordPress, tested it was very fast. Like an idiot I forgot that in my flat all devices have internet access, so the fetching of Google Font by twenty-seventeen was holding up the entire page-load & render.

Using your plugin takes that problem off my hands without changing theme or writing my own plugin, so 5*. I just wish you used currying instead of having so many functions that are 99% the same.

Works great for a raspberry Pi

Good plugin to get rid of the privacy hole that is Google Fonts.
I still can't understand why it was let in the Wordpress Core ...I should not need a plugin for that -_-

Does what it says

Disable enqueuing of fonts from Google used by WordPress core, default themes, Gutenberg, and many more.
