Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

Overview
About this plugin
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.
External Services
This plugin sends image data to an external API service operated by HostSalt:
API endpoints: https://images.hostsalt.com/optimize and https://images.hostsalt.com/usage/{site_id}
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
This service is operated by HostSalt. Please review the following before use:
