HostSalt Image Optimizer connects your WordPress site to the HostSalt IO cloud API to automatically compress and convert images on upload. No server-side libraries required — just install, connect and start saving bandwidth.
Features:
- Automatic optimization on upload — no manual steps needed
- Converts images to WebP or AVIF for maximum compression
- Smart format selection — picks whichever format saves more
- Lossless backup — restore originals any time with one click
- Bulk optimize your entire existing media library
- Bulk restore all images to their originals
- Monthly usage dashboard built into wp-admin
- Works with all themes and page builders
- Multisite compatible
How it works:
When you upload an image, HostSalt Image Optimizer sends it securely to the HostSalt IO API. The API compresses and converts the image, then returns the optimized version. The original is kept as a backup so you can restore at any time.
A free plan is available with 50 optimizations per month. Paid plans are available for higher volumes.

- Data sent: image file contents, output format preference, quality setting, max width setting, and a unique site identifier derived from your site URL (MD5 hash)
- Data received: optimized image file
- When: on image upload (automatic), on manual Optimize button click, and during bulk optimization
