This plugin adds 15 web safe font families to the WordPress block editor&#8217;s typography panel. No Google Fonts, no external requests, no JavaScript font loaders, CSS import — just the fonts that are already installed on your visitors&#8217; devices.
Web safe fonts are pre-installed on Windows, Linux operating systems, which means they render instantly without any network request. Your website loads faster, looks consistent across devices, and avoids layout shifts caused by font loading.
We have a Plan B! When a visitor uses a different operating system or device, the plugin loads the same or an alternative font, so the design won’t change.
Available fonts:
Sans-serif 
&#8211; Arial (Alternative: Liberation Sans) 
&#8211; Verdana (Alternative: DejaVu Sans) 
&#8211; Tahoma (Alternative: DejaVu Sans) 
&#8211; Trebuchet MS (Alternative: CabinCondensed)

&#8211; No additional privacy, GDPR, or cookie measures required

How it works 
The plugin registers the font families in the theme.json data layer via the <code>wp_theme_json_data_theme</code> filter. This makes them appear alongside your theme&#8217;s own fonts in the Typography panel of every block that supports font selection. The corresponding CSS classes are enqueued as inline styles, so fonts are applied correctly both in the editor and on the frontend.
