I tried converting jpg, gif and png files....both gif and png converted into webp are much smaller.

JPG however is not. I will continue to use JPG until webp is smaller.

I see all these people saying how JPG-->WEBP is smaller, but over 5,000 tests........not for me.

I use GIMP (whatever the latest version is).

For someone who uses a lot of photographs........even 3kb will make a difference. Any of you photographers out there will understand what I am saying, right?
