Squidge

This free plugin automatically compresses and converts uploaded images to improve website performance. It is designed for developers and site administrators who need a reliable, no-cost solution for managing image assets.

Automatic Processing: Images are compressed and converted to modern formats like WebP and AVIF as soon as they are uploaded to the media library. Command Line Control: Includes a WP-CLI tool to regenerate all media files in bulk, with options to control quality and disable specific conversion types. Template Helper Function: Provides a PHP function to output responsive <picture> elements in templates, automatically serving the most efficient image format the browser supports. No File Size Limits: Processes images of any size without restrictions, unlike many paid services. System Library Integration: Relies on installed system tools (jpegoptim, optipng, cwebp, libavif) for compression, giving developers control over the underlying optimization engines.
