GIF Speed Changer

Viewers can clamp very short frame delays, changing playback speed. This tool uses a 20 ms minimum and may merge frames when a higher speed requires it. Timing is rounded to GIF precision; inspect the encoded duration and test the destination app rather than assuming exact playback everywhere.

Yes. Every frame’s delay is scaled by the same amount, so a pause the creator built in stays proportionally longer than the other frames. At very high speeds, minimum frame delays and frame merging can limit exact timing. Try 1.5× or 2× before jumping to 4×; for a slower demonstration, 0.5× is a useful first comparison. Slowing playback holds existing frames longer and does not generate new intermediate frames, so low-frame-rate motion may look less smooth.

Reverse plays the GIF backwards once per loop. Boomerang plays it forwards and then backwards, which creates back-and-forth playback, not a guaranteed seamless loop — useful for gestures or objects moving between two positions. It can look unnatural for falling objects, poured liquid or written instructions, because those actions visibly undo themselves. Preview both directions before choosing the effect.

Usually not by much; only when frames have to be merged at very high speeds does the file shrink. Boomerang nearly doubles the frame count, so expect a larger file. Use the GIF Compressor if you need to fit a limit.

Yes. Tick “Play once instead of looping forever” before applying. Most apps then stop on the last frame. Test the exported GIF in the actual destination because some viewers override loop settings. Keep a looping copy if you need to compare how the same animation behaves in a browser, presentation or chat app.

No. Everything runs in your browser and the GIF never leaves your device.
