Description
Compressify connects WordPress to the Compressify API so new uploads and existing media library images can be optimized outside your hosting environment while keeping WordPress attachment metadata intact.
The plugin can optimize uploads automatically, convert output files to modern formats such as WebP or AVIF, and run background passes for older media items already stored in the library.
With Compressify, you can:
* Automatically compress JPG, PNG, and WebP images upon upload.
* Convert legacy images to next-generation formats like WebP or AVIF.
* Reduce bandwidth usage with smaller image payloads.
* Improve Core Web Vitals (LCP, CLS) and PageSpeed-related performance metrics.
* Bulk optimize your entire existing media library with a single click.
To use this plugin, you will need a Compressify API key from your account at https://compressify.net.
