GIF Maker

Every frame of a GIF has to share one canvas, so something has to give. "Fit inside" scales each frame to fit and pads the leftover space, which never distorts anything — that's the default. "Fill and crop" scales up until the canvas is covered and trims the overflow. "Stretch" squashes each frame to the exact canvas shape, which does distort, and is there for the rare case you want it.

Yes — it plays your actual frames at your actual timings, using the same fit and alignment maths the server uses. The exported GIF is what you watched, so the order and speed can be settled before you export rather than after.

Up to 30. GIF stores every frame as a full image, so file size grows quickly — a long animation with large frames can easily reach tens of megabytes.

Yes. Set the overall speed with the delay control, then give any individual frame its own timing from its card — useful for holding the first or last frame a little longer.

GIF is limited to 256 colours per frame — that's a limitation of the format itself, not of this tool. Photographs and smooth gradients suffer most. There's nothing to change in the settings; a video format would be the better choice for that material.

Yes — turn on Ping-pong and the frames are appended in reverse, so the animation runs forwards then backwards without a jump at the loop point.
