Page guide

Speed up a GIF or slow it down while keeping the same frames and loop count.

How to use Change GIF speed
  1. Upload a GIF and enter a speed multiplier from 0.1 to 10. A value of 2 plays twice as fast; 0.5 takes twice as long. Run the tool and preview the result.
  2. The tool divides each frame delay by your multiplier. Nonzero delays round to 10 milliseconds, with a minimum of 20 milliseconds. GIFs with unusually short or zero delays can play differently across browsers.

How timing changes

The tool divides each frame delay by your multiplier. Nonzero delays round to 10 milliseconds, with a minimum of 20 milliseconds. GIFs with unusually short or zero delays can play differently across browsers.

Limits and privacy

Files stay in your browser. Use one GIF up to 20 MiB, 120 frames, 1,920 pixels per side and 16 million decoded pixels across all frames. The frame sequence and loop count are kept. Re-encoding can slightly change colors. Your original file is unchanged.
