WebP Conversion Issue in XenForo 2.2.15

[XFFA.IR Bot]

Hello,

I'm trying to develop an add-on for XenForo 2.2.15 that automatically converts uploaded images to WebP format. I've used some code, but it's not working properly.

Here's what I've tried:

1. Added code to the Attachment.php file in the add-on.
2. Attempted to use the Imagick library.
3. Tried reducing the size of the uploaded images.

Problem:

The images are still being uploaded in PNG format and are not being converted to WebP.

Could someone please help me with this? Are...
