Speed up or slow down any GIF from 0.25× to 4×. Frame delays are adjusted instantly — file size stays the same.
Each GIF frame has a delay value (in centiseconds). Speeding up divides all delays by the multiplier; slowing down multiplies them. The visual content of each frame is unchanged.
No — only the timing metadata changes. The file size stays exactly the same.
This tool supports 0.25× (quarter speed) to 4× (four times speed). Most browsers will cap very fast GIFs at around 50 FPS regardless.
Yes — use the slider to find the right multiplier, or use Trim GIF to reduce frame count before adjusting speed.
