Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

Overview

About this plugin

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.

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.
