i am perfectly aware of that, but if you only want to view the .webp file outside of your browser, you don't need to convert it properly, just rename the extansion

Yes, and no. No app will display the image if it wasn't already capable of displaying webp, period.

However, there are many places (mainly websites where you can only upload certain formats, but it can also be apps) where the underlying infrastructure supports webp, but they do a simple extension check first with a list of file extensions that doesn't include .webp. In those cases, changing the extension to .jpg will get the image through the filter, and the underlying system will detect the format using the magic number at the beginning of the file.

The same thing can happen when your OS has no associated app to open .webp, but the app it uses for .jpg can also display .webp.
