Frequently Asked Questions
Common questions about WebP Image Optimization
Yes, starting from version 1.4.0, you can convert existing JPEG and PNG images to WebP directly from the Media Library using the new conversion option.
By default, the original images remain on the server. You can choose to delete them manually if desired.
Yes, the settings page allows you to exclude JPEG and/or PNG images from being converted to WebP.
The plugin requires the GD library with WebP support enabled on your server. Most modern servers have this capability. If not, contact your hosting provider.
Most modern browsers support WebP images. For browsers that do not support WebP, the plugin ensures that the original image formats are served as fallbacks.
Yes, you can set the JPEG quality (0-100) and PNG compression level (0-9) via the settings page to balance between image quality and file size.
After conversion, the plugin displays the original and WebP file sizes in a readable format (KB/MB) along with the amount of file size saved both in bytes and percentage.
