It's an image format ghat saves a lot of data. I use it all the time to save space!

I hate them because my image viewer of choice doesn't support them and never will because supposedly the developer died and never released the source.

I don't know what they are other than a file format; but I also don't know what everyone's problem with them is. They open in every viewer or editor I've used just fine so you can convert them by just saving as a new format if you're trying to reupload them somewhere.

It's a newer image file format. You could think of it as a "better" version of a GIF or PNG. It compresses to a smaller file size with better quality, so lots of sites are using it now to speed up image loading without sacrificing quality.

This seems like the crowd to have ffmpeg installed. Ffmpeg will convert webp to jpeg real easy, don't even need to specify a converter.

Image file format with excellent compression. It’s designed for web browsers, so what you’re probably running into is compatibility with other programs. It’s fairly easy to convert though to GIF or JPEG formats though.

I stick to png

Usually you can inspect the web page and find the original jpg to download. Its annoying though.

Here’s a tip: a lot of websites actually store and serve multiple copies of an image in different formats because not all browsers support newer formats. If you change the name of the file you’re viewing in the browser from .webp to .jpg, chances are you’ll see a jpeg version of the same image provided by the same server.

They’re a pain in the ass sometimes because I can’t say, download one and send them in certain chat programs. But you can use a program like Gimp to convert them easily.

All programs that I use support them - what are these ancient apps that don't?

You can take them into GIMP (or probably any image editing software) and turn them into png or what have you.
