Converter for Media Pro converts JPEG, PNG, and GIF images in WordPress into WebP and AVIF versions. These copies are intended to reduce the image file sizes delivered to visitors while keeping the original documents unchanged.

Browser-based format delivery

When AVIF is enabled in the plugin settings, the plugin checks a browser’s supported formats as an image loads. A browser that supports AVIF receives the AVIF version. If it does not support AVIF but supports WebP, it receives the WebP version. If it supports neither format, the original image loads.

The product information describes AVIF files as about 50% smaller than images converted only to WebP while maintaining better image quality.

Optimize existing and new images

After installing the plugin, execute one-click optimization for images already in the WordPress Media Library. Images added to the library later are converted automatically.

Where converted files are stored

WebP and AVIF copies are saved separately in /wp-content/uploads-webpc/. The plugin leaves original images unchanged and, according to the product information, removes the converted files it created if you remove the plugin.
