FAQ

Does this plugin change the image URLs to WebP?

No. The original image URLs (e.g.,
.jpg,.png) remain unchanged, which ensures full compatibility with themes and existing content. The file contents are replaced with WebP internally. -
What if my server does not support Imagick?
-
The plugin will automatically fall back to GD’s
imagewebp()function if Imagick is not available on your server. -
Can I control the compression quality?
-
Yes, you can set your desired WebP image quality (0–100) through the plugin settings panel.
-
Can I remove metadata from images?
-
Yes, there is an option in the settings to strip metadata during conversion to reduce file size.
-
Will previously uploaded images be converted?
-
Currently, only newly uploaded images are converted. A bulk conversion tool may be added in a future version.
