100% local compression
Optimise 10 images or 10,000. No per-image fees, and no third-party API ever sees your files.
Free plugin
Papepo Local WebP Converter
Why pay for image compression? Enterprise-grade WebP conversion, free, on your own server.
Stop spending on monthly API credits. Convert images to WebP locally. Your media never leaves the server.
Full features
Automated WebP conversion
Bulky JPGs and PNGs become WebP, and the front end is rewritten to serve them.
Set-and-forget auto-optimise
New Media Library uploads are converted immediately. The bulk optimiser works through the existing library in the background.
Total control and safety
Set your own quality (80% is a good start). Keep original backups, or delete them to reclaim disk space.
Why use this?
The other tools
Charge per image, demand an account, and slow the site by shipping files to their cloud.
PAPEPO Imagizer
One-click install, unlimited use, local processing, and built-in WebP rewriting.
Ready to speed up your site and cut disk usage?
Images are processed locally with your server’s GD or Imagick libraries, which uses CPU and memory during a bulk run. Deleting originals is permanent. Take a full backup before the bulk optimiser. PAPEPO is not responsible for data loss, timeouts, or artefacts from high compression. No image data is sent to external servers.
