== Frequently Asked Questions ==

= Does this plugin convert existing images in my media library? =

No, the plugin only processes images uploaded after the plugin has been activated. Existing images will remain unchanged.

= What happens to the original JPEG or PNG files after conversion? =

By default, the original images remain on the server.

= Can I exclude certain image types from conversion to WebP? =

Yes, the settings page allows you to exclude JPEG and/or PNG images from being converted to WebP.

= What if my server doesn't support WebP images? =

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.

= Will the converted WebP images work on all browsers? =

Most modern browsers support WebP images. For browsers that do not support WebP, you may need to implement a fallback mechanism. This plugin does not provide fallback functionality.

= Can I adjust the image quality and compression settings? =

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.
