How to Change GIF Speed

Adjust the playback speed of any GIF — make it snappier or slower — in seconds, directly in your browser.

Step-by-step guide

1
Upload your GIF
Go to gifmash.com/gif-speed and upload your GIF. The tool shows the original duration and frame count.
2
Set the speed multiplier
Use the slider or preset buttons to set a speed between 0.25× (slowest) and 4× (fastest). The new duration is previewed in real time.
3
Apply and download
Click Apply Speed. The tool uses gifsicle's --delay flag to adjust each frame's display time. Download the result.

Free GIF speed changer — 0.25× to 4× range, no upload required.

2× speed halves the frame delay — useful for making long GIFs snappier.
0.5× speed doubles the delay — good for slow-motion effects.
Speed changes don't affect file size since they only modify frame delay metadata.

Does changing GIF speed change the file size?

No — the --delay flag only changes the timing metadata in the GIF header. Frame data is unchanged.

What is the fastest possible GIF speed?

GifMash's maximum is 4× (minimum delay = 2–3 centiseconds). Most browsers enforce a minimum GIF frame delay of 20ms anyway.
