For the image title of my website medium-small(150x50) white background with some effects on title (example: google title image)
I saved the image in .gif and .png with result:
.gif size = 3.09 kB .png size = 7.59 kB
The .png is 2x bigger than .gif.
Everyone are saying me to use .PNG, but why I should use it if .gif are better
