I don’t know what a .webp file is but I don’t like it. They’re like a filthy prank version of the image/gif you’re looking for. They make you jump through all these hoops to find the original versions of the files that you can actually do anything with.
Edit: honestly I assumed it had something to do with Google protecting themselves from image piracy shit
.webp was developed Google so of course Microsoft hates it and tried to hinder it’s adoption.
They also don’t, by default, support HEVC and charge you to open them now… it used to be a free app on the Microsoft store.

That’s not on Microsoft. HEVC is not royalty free standard, so Microsoft had no chocie.
I can recommend qimgv for an image viewer.
