WebP Converter for Media

WebP Converter for Media is one of the best plugins for WordPress, In Which all images can be converted in one click. This tool uses WordPress REST API to download all images addresses and convert all files slowly. This process can take several minutes or longer depending on how many files you have. Please do not close your browser during this process.

After installing the plugin, this operation should only be done once. The Media Library will automatically convert any new images.

How does WebP Converter for Media works

Images can be added to your media library and automatically converted and saved in separate directories. Images are converted with the native PHP extension GD or Imagick.

The server checks if the browser can download an image file. If all is fine, the browser will be able to download the equivalent image in WebP format.

The default loading mode plugin (via.htaccess), does not alter file URLs. This means that saving the page to the cache is possible without any problems and page generation times do not increase.

Modifying image URLs is done using mod_rewrite, which is a module on the server. This allows us to use friendly links in WordPress. The MIME type of the file sent is also changed to image/WebP.
