When I try to preview a webp file I get the “WebpQuickLook.qlgenerator” cannot be opened because the developer cannot be verified., how did you manage to make it work @Polaris-Dust ?
Have you tried xattr -d com.apple.quarantine ~/Library/QuickLook/WebpQuickLook.qlgenerator
This worked for me too, but when you ask it as a question like that, my response is "why would I have tried that?"
Seems to me this problem affects 100% of new installations. If that command is the way to fix it, maybe it could be integrated into the brew solution, and listed on the readme for people installing the app?
Thank you @appdev – after a few failed attempts I finally got it to work for QuickLook. Unfortunately I don’t get thumbnails in Finder ... I tried to do what @Polaris-Dust suggested but don’t know which specific file/app I need to add where in the Privacy Settings ... can you please help me do that right? Thank you!
i have load from Apstore the App. WebP Viewer: quick look & view, this works :)
Thank you for the alternative.
sudo xattr -rd com.apple.quarantine ~/Library/QuickLook/WebpQuickLook.qlgenerator
This solution started working for some reason.
qlmanage -p /Users/custa/git-projects/sofa/images/cdn-sports/netball/11391/801/999806-headshot.webp

is what I get when I try to quicklook it from the command line. When I try just using space for quicklook I do not get a preview, and the icons are generic image icons. I have trie all the suggestion above in this thread but am still not getting it to work.

It worked for me only if I install it from the App Store. Thanks @doitauto !
bissy commentedon Jun 29, 2020
It worked for me!
After installing with terminal.app, works only QuickLook (not Thumbnail),
but After restart Mac, It works!
Thank you!
AddictArts commentedon Dec 8, 2020
@fharper @doitauto How do you load from App Store or install from the App Store? This qlgenerator is not in the App Store. Thanks
fharper commentedon Dec 10, 2020
oh, I didn't realize but I install another app with the same name, sorry for the confusion.

I think you need to allow full harddisk access for your terminal application.

Just found out about this fix and can confirm it still works on MacOS Catalina 10.15.7 and Safari 15.6.1.
I used this command to install it:
curl -L https://raw.github.com/emin/WebPQuickLook/master/install.sh | shNo reboot required. Works well with Google WEBP example images.
