Description

Studiya Optimizer is a single-file WordPress must-use plugin that covers every major performance area: script loading, image optimization, CSS/JS delivery, and advanced server-side tuning. Drop it in mu-plugins/ and every feature activates immediately — no configuration required.

Features

Phase 1 — Performance

  1. Smart Script Loading — defers non-critical scripts; forces async on Analytics/GTM; strips defer from protected handles (jquery, wp-i18n, etc.) to prevent media-library breakage.
  2. Resource Hints — DNS-prefetch for Google Analytics and GTM; dynamic <link rel="preload"> for the site logo (improves LCP).
  3. Disable Emoji — removes emoji detection scripts and styles (~11 KB per page).
  4. Clean HTML Header — strips generator tag, RSD, WLW manifest, shortlink, and REST API discovery links from <head>.
  5. Disable XML-RPC — blocks xmlrpc.php and removes the X-Pingback header.
  6. Disable RSS Feeds — optionally redirects all feed URLs to the homepage (301). Off by default.
  7. Cache Navigation Menus — transient-caches rendered nav menus for 12 hours; auto-flushes on menu or post save.

Phase 2 — Image Optimization

  1. Lazy Loading + LCP Priority — first large image (≥200 px wide) gets loading="eager" fetchpriority="high"; all others get loading="lazy".
  2. WebP Conversion & Serving — on upload: generates .webp sidecars for every size via GD. On frontend: wraps <img> in <picture> with full srcset.
  3. Compress on Upload — JPEG → quality 82; PNG → zlib level 7. Files under 100 KB are skipped. Original saved as filename.ext.backup.
  4. Add Missing width/height — ensures image tags carry width and height attributes to prevent CLS.

Phase 3 — CSS/JS Optimization

  1. Minify Inline CSS — removes comments and collapses whitespace inside `
