About this plugin
WebP Image Converter & Replacer converts your images (JPEG, PNG, static GIF) to WebP , replaces originals only when smaller , and updates database references so your site transparently serves .webp . No duplicate files. No front-end bloat. Just faster pages and less disk usage . Why this plugin – No Duplicate Images: Converts and replaces originals when WebP is smaller, keeping /uploads lean. – Real Performance Gains: WebP typically reduces size ~25–35% at similar quality, aiding Core Web Vitals. – Safety First: Never deletes the original unless conversion succeeds and the WebP is smaller. – Full DB Integration: All generated sizes are converted; URLs in content/meta are updated to .webp . – On-Server Only: Uses PHP GD or Imagick . No external API, keys, or privacy concerns. – Lightweight: Runs only during conversion—nothing extra on the front end. Free features – Convert individual images from Media → Library (list view). – Optimization Overview with counts: convertible, converted, remaining, skipped, failed, total space saved. – Smart memory handling to avoid PHP exhaustion on large images. Premium features – Auto-convert on upload: New images become WebP automatically. – Bulk convert selected: Multi-select in Media Library (list view). – Bulk convert all: Library-wide conversion with progress + pause/resume. Whether you’re tight on storage or chasing better performance, this is a safe, effective way to modernize images. IMPORTANT: Because originals may be deleted, back up your /wp-content/uploads/ and database before converting. Test on staging if possible. How it works Plugin checks server support (GD/Imagick with WebP). You convert images (single/bulk/premium auto). If the .webp is smaller, the original file is removed and all DB refs switch to .webp . Your site now serves WebP transparently—no theme changes required.
