it works and is open-source

Very good extension to rid of that webP rubbish. But it needs one option to make it perfect. When you have an image loaded in its own tab, and you attempt to save the image quickly using CTRL-S, the extension is completely bypassed, and uses the default browser save dialog, folder choice, and filename. An option is needed to save images through the extension should you use CTRL-S, so that it can take advantage of the extension's ability to convert to JPG, as well as modify the filename before saving. Currently as it is, you still have to Right-click on the image and go down to "Save webP as..." which makes it a lengthy process for multiple images. The extension should take over CTRL-S if the image is displayed by itself.

Всегда раздражало, что некоторые картинки сохраняются в ссаном webp

works great

10/10 it just works as intended and has some cool options as PNG or JPG with a lower scale too super useful and convenient now that everything is a WebP

I've been using this multiple times per day (Steam really hates webp and sometimes clip tool isn't sufficient) for years and love it.

It does what it claims to do and it does it well.

Finally, one that works!

I use them together with YouTube video editing. It's amazingly useful. 👍️

It's very useful. I hate the webp image format.

It's handy to convert pesky webp images.

Works perfectly.

Love it!! Really great work, thanks a lot! Plus the hotkey idea (shift+click, save as PNG ; ctrl + click, save as JPEG) is the cherry on the cake. I don't get it why there are so many Miesmacher und Kritikaster in the reviews, but some people are born vinegar drinkers that can never be pleased, don't let it get you down, it's a perfect add-on imho.
