原文外掛簡介
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.
