Speed up or slow down a GIF

The GIF Speed Changer makes an animated GIF play faster or slower by rewriting each frame’s delay — from a quarter speed (0.25×) up to four times faster (4×). Because browsers slow down frames shorter than 20 ms, very fast settings drop frames instead so the requested speed is actually what you see.

How to use GIF Speed Changer

  1. 01

    Upload a GIF

    Drop the GIF you want to speed up or slow down.

  2. 02

    Apply and download

    Click Change speed and download the new GIF.

The 20 ms rule

GIF stores delays in hundredths of a second. Browsers treat any delay under 20 ms (2 hundredths) as “too fast” and slow it to 100 ms — a 0 ms or 10 ms GIF actually plays at 10 fps. That’s why naïvely halving delays can make a GIF play slower. This tool never writes delays below 20 ms; when you ask for more speed than that allows, it drops frames instead, so the visible speed matches your setting.

You can check any GIF’s real timing with the GIF Tester, and repair GIFs that are stuck too fast or too slow with Fix GIF.

Speed, length and file size

Speeding up shortens the GIF; when frames are dropped the file shrinks too. Slowing down keeps all frames, so the size stays about the same while the duration grows. To shorten without changing speed, trim instead. For rhythmic effects, try a boomerang or set loop counts with the GIF Looper.

GIF Speed Changer FAQ

How do I make a GIF faster?

Upload the GIF, move the speed slider above 1× (for example 2× for double speed) and click Change speed. Download the faster GIF when it’s ready.

Why does my GIF play slower than its frame delay says?

Browsers treat GIF frame delays under 20 ms (often 10 ms or 0 ms) as 100 ms, which makes “too fast” GIFs play slowly. This tool keeps delays at 20 ms or more and drops frames when you ask for more speed.

What is a GIF frame delay?

Each GIF frame stores how long to show it, in hundredths of a second. A delay of 100 ms equals 10 frames per second; 50 ms equals 20 fps.

Are my files uploaded to a server?

No. GifRush processes everything locally in your browser using JavaScript, Canvas, Web Workers and WebCodecs. Your files never leave your device, and closing the tab discards them.
