This plugin processes and compresses uploaded JPEG images directly on your server in real-time. It is designed for site administrators who need to reduce page load times and bandwidth usage by minimizing image file sizes without relying on external services.

Real-time mozjpeg optimization: Images are processed immediately upon upload using the mozjpeg encoder, which typically achieves better compression than standard JPEG encoders.

Server-side execution: All compression work is performed on your own server, keeping image data private and eliminating dependency on third-party APIs.

Configurable socket connection: The plugin communicates with a background worker process via a Unix socket, allowing for flexible deployment and integration into existing server environments.

Reduced file sizes: By applying lossy compression tuned for web use, the plugin decreases the storage footprint and transfer size of media library images.

Manual testing support: Includes command-line instructions to verify the worker process and socket configuration are functioning correctly before enabling live optimization.
