google introduced webp images way back in 2010 but still
Windows default photo viewer doesn't support it. and doesn't looks like it's ever going to.
so let's see how you can fix that problem.
Ok first of all launch google chrome and open webstore.
here we need to install an extension called "Save Image As: JPEG, PNG, WebP, Base64"
once installed right click on any webp image that you want to save
and select "Save image as Type" option.here select the extension that you want your
image to be. it will open a new window here just rename your image
and click on save. that's it guys now you can easily download
any webp image in jpeg or png
