AFAIK, the PDF format has a limited number of allowed image compression schemes allowed. Several of those are obsolete for all practical purposes. Thing is, the list does not include WebP, but the lossy algorithms allowed include JPEG2000, which is usually better than JPEG, and offers much better compression than lossless algorithms such as Flate/PNG.
If you attempt to embed a non-allowed format such as WebP, your PDF generation tool will either refuse it or silently convert to an allowed format such as JPG.
