This isn't a WebKit bug, but rather in ImageIO, given opening it in Preview equally causes an error.

Thanks Sam. Is this Apple's ImageIO? https://developer.apple.com/library/archive/documentation/GraphicsImaging/Conceptual/ImageIOGuide/imageio_intro/ikpg_intro.html If so, can a bug report be filed there?

Created attachment 461525 [details] Another WebP image Here’s another example of a WebP image that fails to load in Safari and Mac Preview. This bug only seems to affect very simple and/or highly compressed images such as this one.

Ah, sorry, I missed this previously. See https://feedbackassistant.apple.com, though I did forward the original bug there. (And it does now work on macOS 13 beta 5.)

That's great, thanks Sam. Hopefully this fix will come to iOS 16 too.

(In reply to Paul Neave from comment #6) > That's great, thanks Sam. Hopefully this fix will come to iOS 16 too. It should also work on iOS 16 beta 5 (it's, uh, just easier to verify on the computer I'm typing on); there shouldn't be any difference here.

Is there any chance that the fix would be backported to earlier versions?
