Peakspire Font Loading Optimizer

Font loading is one of the largest contributors to Largest Contentful Paint (LCP) on real websites. Peakspire Font Loading Optimizer applies the three highest-impact font fixes, built from hands-on Core Web Vitals engineering on production sites:

1. Preload local WOFF2 fonts – Scans your enqueued stylesheets for locally hosted WOFF2 files and adds <link rel="preload"> tags, capped at 4 fonts. Preloaded fonts arrive before the browser discovers them inside CSS files, removing the font round-trip from the critical path.

2. Adds font-display: swap to eligible inline @font-face rules – Rules that already declare an explicit optional, block, fallback, or auto value are never touched. Rules without a descriptor get swap, so text renders immediately with the fallback font instead of sitting invisible while web fonts download.

3. Remove external Google Fonts (optional) – Dequeues all fonts.googleapis.com requests for sites that have self-hosted their fonts.

4. Remove dashicons for visitors (optional) – Dequeues the dashicons stylesheet for logged-out visitors, saving a render-blocking request most themes never use on the front end.

Everything is front-end only and safe to use alongside caching plugins (WP Rocket, LiteSpeed Cache, W3 Total Cache, etc.).

Why only local fonts are preloaded

Cross-origin font preloads waste bandwidth when the crossorigin fetch does not match the stylesheet fetch. This plugin deliberately preloads only same-host WOFF2 files, the safe default for virtually all themes that self-host fonts.
