How could using fonts via Google’s service possibly run afoul of GDPR? The fact of the matter is that, when a font is requested by the user’s browser, their IP is logged by Google and used for analytics.
Leverage Browser Cache, reduce DNS lookups/requests, reduce Cumulative Layout Shift and make your Google Fonts 100% GDPR compliant with OMGF!
OMGF is written with performance and user-friendliness in mind. It uses the Google Fonts API to automatically cache the fonts your theme and plugins use to minimize DNS requests and speed up your WordPress website.
How Does It Work?
After installing the plugin, OMGF will automatically start looking for Google Fonts whenever a page is requested on your website.
All Google Fonts are listed in the Optimize Local Fonts section of OMGF’s settings screen. There, you can choose to:
- Preload fonts to reduce Cumulative Layout Shift above the fold,
- Unload fonts that’re not used by you, your theme and/or plugins,
- Set a Fallback Font Stack (OMGF Pro required), to further reduce Cumulative Layout Shift, or
- Replace (OMGF Pro required) font-families with system fonts to speed up loading times!
Other Features include
- Variable Fonts support,
- Automatically Remove unused subsets to reduce the size of the CSS stylesheet with ~90%!
- Remove Resource Hints (preload, preconnect, dns-prefetch) pointing to
- Ensure text remains visible during webfont load by forcing the font-display attribute to your Google Fonts,
- Ensure text remains visible during webfont load by forcing the font-display attribute to all your other fonts! (OMGF Pro required),
Additional Features in OMGF Pro
- Multisite support,
- «Dig deeper» to find Google Fonts and optimize further. OMGF Pro supports:
@importstatements inside inline
@importstatements inside local stylesheets loaded by your theme and/or plugins,
- Web Font Loader (
- Early Access Google Fonts.
- Material Icons support.
- Modify your fonts’
src: url()attribute fully integrate with your configuration,
- Use this to serve fonts and the stylesheets from your CDN, or
- To serve fonts from an alternative path (e.g. when you’re using Security through Obscurity plugins like WP Hide, etc.), or
- Set a relative path to easily migrate from development/staging areas to production/live, or
- Anything you like!
- Upload the plugin files to the
/wp-content/plugins/host-webfonts-localdirectory, or install the plugin through the WordPress plugins screen directly.
- Activate the plugin through the ‘Plugins’ screen in WordPress
- Use the Settings -> Optimize Google Fonts screen to configure the plugin

- Fixed: Filter duplicate font-family requests in same Google Fonts request, e.g. fonts.googleapis.com/css?family=Roboto|Roboto.

OMGF::debug, because of this and Test Mode now allows for much user-friendly testing, anyway.
OMGF::debug()wrapper is still there for hardcore in code debugging.

- Several code tweaks and fixes.
- Added: Test Mode, which allows you to test optimizations before releasing them to the public.
This option replaces Optimize for Logged-in Administrators/Editors.
- Fixed: several minor tweaks.
- Added: Removed Cache Directory in favor of an automatic approach to improve UX, because most people didn’t change the default value anyway.
- I.e. all files generated by OMGF are stored in a subdirectory of the Uploads folder (default
- For most of you nothing will change, but
omgf_upload_urlfilters are available for DEVs who want to modify the default value, although I really can’t think of a reason why you’d want to do that.
- I.e. all files generated by OMGF are stored in a subdirectory of the Uploads folder (default
- Reworded description of Optimize for logged-in Administrators/Editors option.
- Added: Compatibility with Mesmerize Pro theme; this theme loads Google Fonts asynchronously, which causes CLS.
- Added: UNIX timestamp cached stylesheets to make sure browser cache of visitors is busted, upon cache refresh.
- Fixed: Running Save & Optimize a 2nd time could trigger some firewall rules, due to the serialized array being passed along with the settings form’s POST action. This serialized array is now stored in the form using base64_encode() and decoded before being saved to the database.
- Fixed: Since the Google Fonts API has removed the
subsetsparamater and returns all subsets by default, OMGF now does the same. Unlike the Google Fonts API, OMGF does still respect and apply the parameter if it set, because it is still used by many themes and plugins.
- Re-worded Force Subsets (Pro) featured to clarify this behavior.
- Fixed: Some resource hints that were added using unconventional methods (i.e. not using
wp_resource_hints()) weren’t removed.
- Fixed: If no regular Google Fonts stylesheets were present, the
omgf_processed_htmlfilter would never be triggered.
- Fixed: Stylesheets on AMP pages would be rewritten to local stylesheets, while this is not supported by AMP.
- Removed: AMP handling (Pro) option from Advanced Settings, because it’s no longer supported by AMP.
- Fixed: don’t allow starting buffer twice.
- Fixed: always run if omgf_optimize parameter is set.
- Fixed: Use Site Address (URL) to run first optimization scan, instead of WordPress Address (URL), because the WordPress install URL can differ from the frontend URL.
- Fixed: Make sure stylesheet URL is properly decoded and HTML entities, etc. are removed, before attempting to process it. (This would cause parameters, like
display, to get lost).
omgf_optimize_query_subsetfilter to OMGF_Optimize class.
- Fixed: Previous versions of OMGF would save stylesheet handles without the appended ‘-css’ string. This is now brought back to guarantee a smooth transition to v5.
- Fixed: If
?nomgf=1parameter was set, preloads would still be loaded.
- Fixed: Added an extra check if file exists, before adding font files for preloading.
- Enhanced: A small speed boost for Save & Optimize.
5.0.0 – **The Better, Bigger, Faster, Stronger, Cooler, Awesomer Edition** | March 4th, 2022
- Added: Parse entire HTML document for Google Fonts stylesheets (instead of just wp_head())
- Added: Merged both Optimization Modes option into one automatically running option:
– A first scan is done upon Save & Optimize,
– A quick check is done on pageload, to see if other Google Fonts are found than the ones already found, and if so, they’re downloaded and replaced on-the-fly.
- Enhanced: The Download API is replaced for an easier, leaner and faster alternative and no longer uses the WordPress API.
– If the first request fails, a mirror is used to retry the request, before throwing an error.
– Fixes rest_no_route errors in some configurations.
- Enhanced: The Task Manager now offers a quick overview of downloaded stylesheets and their status, along with simple management tasks, e.g. cache flush, configure stylesheet and/or remove.
– When cache is marked as stale, it’s now possible to refresh the cache and maintain your stylesheet configuration.
- Added: Resource hints enqueued in wp_resource_hints() are now properly removed.
- Fixed: Smart Slider 3 compatibility.
