Hi @juanwp22,
Thank you for your message.
The plugin does not modify or delete your original files. Thanks to this, your images are always safe and the images work in any browser. Please note that the WebP format is not supported by 100% of browsers.
When a browser tries to download an image file, the server checks if it supports the AVIF format (if enabled in the plugin settings). If so, the browser will receive the equivalent of the original image in the AVIF format. If it does not support AVIF, but supports the WebP format, the browser will receive the equivalent of the original image in WebP format. In case the browser does not support either WebP or AVIF, the original image is loaded. This means full support for all browsers.
Best,
Mateusz
