Webp Transformer is a WordPress plugin designed to streamline image management by automatically converting all uploaded PNG and JPG files to the WebP format. This plugin simplifies the image handling process by ensuring that images are optimized for web use, enhancing loading speeds and improving overall site performance. It's important to note that original images are not preserved during this process, as uploads are transformed directly into WebP files upon entry into the WordPress library.

Key features of Webp Transformer include customizable conversion quality settings, which allow users to balance image quality and file size according to their needs. Additionally, users can define maximum dimensions for images; any uploaded image exceeding these dimensions will be automatically resized. The plugin also offers flexibility by allowing users to exclude specific images from conversion based on their file names.
