>>7605137 (OP)I believe it is actually significantly more efficient than other image formats, but it is annoying because so few programs actually support the damn thing outside of browsers.
I wouldn't even mind it if I could at least look at the images in windows' image viewer, but of course it doesn't support the file type.
Anyway, the quick trick to saving the file in a better format is to just quickly copy and paste it into a drawing program (even paint) and just save it as a png or jpg like that.
I think there's even browser extensions that automate that - because the file type is loathed for its inconvenience (again, through lack of support).
So not really google's fault, but I hate google, so fuck 'em.
Though, I am curious for the lack of support given the format's positives.
