WebP compression

In image settings, I’ve checked Create WebP version of image. Your help for Create WEbP version of image says “Creates WebP image format and serves it whenever possible.”

I use Elementor Pro and see that optimizing JPEGs as WebP does not work for their thumbs (and a few other items) which still are served as jpegs so I tried uploading WebP files for original images which works ok with Elementor thumbs. But now if I run your image compression on the uploaded WebP files, I get errors. I’m assuming this is because the images are already WebP format?

… 3 selected image(s) could not be compressed. Please see the logs for more information, you may try again later. Log says:

Task with ID 626 and type (smush) failed with error code invalid_file_type – …./.webp – cannot be optimized, it has an invalid file type

I was hoping that when I select a jpg file, it would serve my WebP image, but it doesn’t. I guess I can just use WebP images but hate to not have a jpeg fallback.

I do use Cloudflare free version if that is an issue.

Any solution?
