Will this overwrite my original images?: Only if you choose the overwrite option. Otherwise, new WebP images are created as separate attachments.
Does it support all image sizes?: Yes, all registered image sizes (e.g., thumbnail, medium, large, custom sizes) are converted.
Can I undo the conversion?: If you chose to overwrite originals, the change is permanent. If new attachments were created, the original images remain intact.

I tested it on a high resolution JPEG and it compressed ~2.5 MB down to 45 KB with minimal visible quality loss at a quality setting of 65. The interface is simple and automatic conversion on upload and page load works smoothly. One point to note is that it also reduced the image resolution so adding options to preserve dimensions and support AVIF format would make it even more versatile. Overall it is a genuinely helpful tool for image optimization and I appreciate the thought and effort put into making the process straightforward.
