About this plugin
Optimize images locally, find possibly unused media, and reduce WordPress backup size safely.
Shrinkwell helps you compress images, generate WebP/AVIF, and review possibly unused media before it bloats your backups. Images are processed on your own server, with no external compression API and no account required.
Run a safe 5-image test first, review the results, then optimize your media library with more confidence.
Built for agencies, freelancers and site owners
Shrinkwell is designed for WordPress maintenance, handoff and cleanup work where you need to show what was optimized, what was skipped, and which media may need review.
Safe image optimization
- Run a 5-image test before touching the full library
- Compress JPEG and PNG files locally
- Generate WebP and AVIF within the monthly free limit
- Resize oversized images
- Strip EXIF/metadata where supported
- Optimize thumbnails alongside originals
- Keep original backups and restore individual images when needed
Safe Media Cleanup
- Scan your WordPress database for possibly unused media
- Review confidence levels and source evidence before cleanup
- See why each image is marked used, protected, possibly unused, or needs review
- Avoid blind deletion with Shrinkwell Trash
- Reduce media library clutter and backup size safely
Delivery and proof
- Confirm WebP delivery on a live frontend URL
- Review optimization logs with bytes saved, skipped images and skip reasons
- Run a site scan and apply recommended settings
- Check missing alt text and weak filenames without auto-rewriting content
Compression profiles
Choose a named compression profile or use custom settings:
- Balanced: solid savings with sensible quality preservation

htaccess edits or a CDN requirement.
