CompressX is a free WordPress image optimization plugin that helps you optimize your website’s images for faster loading times.

You can use it to easily convert JPG/PNG images on your WordPress websites to WebP and AVIF formats, and compress WebP or AVIF images.

Bulk Processing & Auto Optimization

From the plugin settings page, you can get started by processing all existing images in your media library with a single click.

Furthermore, you can enable the ‘auto-processing’ option to automatically convert new uploads to WebP and AVIF formats and compress WebP and AVIF images.

In General Settings section, you can configure how CompressX optimizes your images:

  • Choose compatibility settings for different browsers.
  • Decide whether to remove unnecessary EXIF data from images.
  • Select between GD or Imagick libraries for image processing (consult your hosting provider if unsure).
  • Enable automatic removal of oversized WebP and AVIF files.

Exclude Folders
