Hello all

Just started to come across WebP extension.

Seems to create problems, I can find only one prog on my comp. - Affinity - other than web browsers to open them.

Has the format any merit or is it just another compatability problem.

I know it is supposed to give smaller file sizes but would be interested in a same image comparison.

OK, and Hi Jeff
At first, knowing you, it was an image (WEBP) of a spider urinating.
But I was curious. So I looked for 5 minutes and see that it is a Google creation.
I looked at some samples and great hullabaloo over this format seems to be the allegation that is saves space by making a smaller save with less loss. So I took a peek and noticed that the side by side comparison, jpg to  jfif is smaller by byte size but a hunk of image is cropped off. To me that accounts for the smaller byte size. See Snaps. Right side 20% is missing?
The next thing I tried was to open it; very dicey to find a program that will open it.
Qimage, no!
So I renamed the .fif to .jpg, and guess what? Qimage sees it and for all intents and porpoises treats it same as a JPG. 
 So I wonder what Mike sees.

An interesting thought,  never seen that thank goodness, we have thousands of them.

Done a bit more digging, and find that a web site authoring I and my friend use - WIX - converts our images to this Google inspired format, well google bought it about 2010.

I am aways interested when others fiddle and resize images.

Still trying to get two versions of same image to compare.

I will continue to explore
