AI summary of the plugin's readme

This plugin is for WordPress site owners who want to shrink their image sizes without leaving duplicate files behind. It converts JPEG, PNG, and static GIF images to WebP, replaces originals only when the WebP version is smaller, and updates database references so the site serves WebP transparently.

Frequently Asked Questions

Common questions about WebP Image Converter & Replacer – Convert to WebP, No Duplicates

Only if the WebP conversion succeeds and the WebP is smaller. Otherwise, the original stays. Always keep backups.

WordPress creates multiple thumbnail sizes. Savings are calculated across the original + all thumbs vs. their WebP equivalents. Thumbnails can outweigh the original file, so total savings can exceed the original’s size.

Your site will continue serving the existing WebP files. Settings are removed; deleted originals are not restored.

It converts format using standard WebP quality defaults (approx. 80–85). No downscaling or custom per-image quality controls in this version.

Not via UI. Advanced users can use the webpicr_webp_quality filter (0–100). Default is 80. Example (custom plugin or theme functions.php): add_filter( 'webpicr_webp_quality', function( $quality, $source_path, $dest_path ) { return 72; // lower = smaller files; higher = better quality }, 10, 3 );

Currently WebP only. AVIF may be added when browser and server support are broadly stable.

We auto-detect animated gifs and mark them as skipped, we do not convert them.

Yes. Network-activate, then run conversions per site. Always back up each site first. I hit a timeout/error. Use bulk pause/resume, try smaller batches, or raise PHP memory/time limits. The plugin includes memory guards, but extreme libraries may need server tweaks.

Modern browsers do. Legacy/very old browsers may not; if those matter, use a different approach.

We rely on a dedicated, proven solution for comprehensive, safe URL updates—lower risk, better coverage.
