Frequently Asked Questions
How does GIF compression work?
The optimizer builds one shared colour palette for the whole GIF, stores only the pixels that change from frame to frame, and merges frames that are identical. Optional lossy compression, fewer colours, frame skipping and scaling shrink it further. If the result is not smaller than your original, we tell you and give you the original back.
Will I lose quality?
"Light" is lossless — every frame looks exactly the same (it can only shrink GIFs that were saved inefficiently). "Balanced" uses up to 128 colours and light lossy compression that is hard to see. "Heavy" uses 64 colours, 75% size and every 2nd frame. Use "Custom" for fine control.
What does "frame skip" do?
Frame skip removes every 2nd, 3rd, or 4th frame. This cuts file size proportionally but speeds up the animation. The frame delays are adjusted to keep the total duration similar.
