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
In my personal experience, when downloading .webp files I wasn’t able to upload to the places I needed to much of the time. But I’ve always been able to just slap .jpg to the end of the file name as I used the save as function and that would make it work everywhere just fine.
Actually, just changing the file name doesn’t change the format. If it works, it’s because whatever place you uploaded to already supported webp.
If you download a webp file and you really want jpg, you need to actually convert it, not just slap .jpg on the end.
A pretty large amount of .JPG images are actually .WebP but people simply don’t notice for some strange reason. I’ve already seen several WebP images uploaded to WikiMedia with a JPG extension.
In that context: Websites may offer alternative image formats for the same image. They may offer jpg alongside webp. It’s just not easily discoverable by end users.
Just relaying what worked for me. Tried uploading with .webp and it didn’t work, tried with .jpg and it did. Didn’t matter to me whether it was a real conversion or not.
