About Images to WebP
The WebP Express plugin converts PNG, JPG, and GIF images to the WebP format, which can save over half of the page weight without losing image quality. This can help speed up your website, save visitors' download data, and improve your Google ranking. The plugin offers automated testing to ensure compatibility with your server, works with all types of WordPress installations, and does not change the image URL or original files. Developers can also use hooks to customize the plugin's functionality.Screenshots
