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:
