macOS seems to recognize WebP images as such, and seems like it actually tries to display previews of them, but always fails.

They are also associated with Preview application, just like other image formats, but Preview also chokes on it (without any error messages, it just silently fails to open a window).

Does it mean that it's intended to actually work but it fails just on my system for some reason?

In my case, the WebP images are lossless and not animated.

Now it's possible with this Quick Look plugin:

    Worked, though note that as of Catalina, it won't work with the default instructions, due to security restrictions, you also have to run this terminal command: xattr -d com.apple.quarantine ~/Library/QuickLook/WebpQuickLook.qlgenerator – jerclarke Jan 14 at 15:20

    Found that in the Issues of their Github, not sure why it's not integrated into their Readme. Hopefully they will update their setup and that command will no longer be necessary (please reply to this if you discover that's so). – jerclarke Jan 14 at 15:21

Preview cannot open webp.

For full details on what Preview can open can be found here

To view webp files, you need to download the framework from Google

    > 'Files are not associated with the "Preview" application. They are associated with their respective applications that can open/edit them.' — this contradicts the fact that when I try to open them, Preview is launched. (to be honest, I don't remember if I manually did set it up that way, but I doubt I did) – Display Name Jun 3 '17 at 15:58
  • So, when you have Photoshop installed, what opens it? Preview or Photoshop? When PS is installed can Preview still open it? – Allan Jun 3 '17 at 16:00
  • I can't try this because I don't want to spend money on Photoshop license nor do I trust it. I can try with GIMP though. But I don't see how installed GIMP would magically help Preview to understand files which it can't understand now. – Display Name Jun 3 '17 at 16:02
  • PS was an example - regardless. Preview has no ability to view webp. – Allan Jun 3 '17 at 16:03

If you use Homebrew then you can enable preview (default hotkey: spacebar) with this one command:

brew cask install WebPQuickLook

  • That's QuickLook "previewing" (as posted by Axifive); we are talking about Preview.app the image/document display program. That, and Finder (as shown in OP's question). – Tom Hundt 2 days ago
