Sometimes I use chrome web clipper to clip some pages to my notes, I could not view the webp images in the note.
Just try to clip this page: https://developers.google.com/speed/webp/gallery1
And you can reproduce the issue, you can't see those webp images. Very annoying.
I'm not sure this is a clipper problem, I think it might be that Evernote doesn't support webp image.
I attached two images, that's how it looks on my web evernote and evernote Mac app, it's simliar on my iOS devices.
Could you add support to webp format? I think more and more webp images are used on web now.
