Core Essentials

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 <code>.webp</code>. 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 <code>/uploads</code> 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 <code>.webp</code>. 
– 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.
<blockquote>
Whether you’re tight on storage or chasing better performance, this is a safe, effective way to modernize images.
</blockquote>
IMPORTANT: Because originals may be deleted, back up your <code>/wp-content/uploads/</code> and database before converting. Test on staging if possible.
