This free GIF speed changer plays your animated GIF at the speed you pick, live, whether you want to speed up GIF animations or slow down GIF animations: drag the slider anywhere between 0.25x and 4x - it clicks into common speeds like 0.5x, 1x and 2x - and the preview animates at the new pace immediately. When it looks right, download it. With Compare with original switched on, the original keeps playing beside the retimed copy so the difference is plain to see - a 4 second GIF turned 2x plays in 2 seconds at twice the frame rate.
Most GIF speed tools decode every frame and rebuild the whole file, which re-quantizes the colors, can dirty the transparency, and takes long enough to need a progress bar. This tool does something simpler and better: a GIF stores a small timing value next to each frame, and changing the speed only rewrites those timing bytes. Every pixel, palette and frame in your download is byte-identical to the original, the file size barely moves, and the change is instant no matter how large the GIF is. At 1x the download is exactly the file you uploaded.
Use it as a GIF speed editor and adjuster in both directions: as a GIF speeder or accelerator that increases the speed to make GIFs faster, or as a slow-motion maker that reduces it for a slower, smoother-looking animation. Speeding up works for trimming the boredom out of screen recordings, making reaction GIFs snappier, or building a fast-forward effect - 1.5x to 2x is usually the sweet spot before motion starts to strobe. Slowing down to 0.5x or 0.25x makes a slow-motion effect and gives fast, jittery GIFs room to breathe. Because the frames themselves never change, you can re-run the tool on its own output as often as you like without any generational quality loss.
GIF timing counts in hundredths of a second, and browsers refuse to show a frame for less than 2 hundredths - anything lower is bumped all the way up to a sluggish 10 by the browser itself. So a GIF that already runs near 50 frames per second cannot get faster through timing alone, and "sped up" GIFs from tools that write those tiny delays come out slower instead. This tool never writes a delay below the floor. When you ask for more speed than the floor allows, it keeps up by dropping frames - at 4x on a 50 fps GIF every fourth frame stays, each showing for the minimum time, so the animation covers the same motion in a quarter of the time. When the frames stored in the file each paint the whole picture, the drop is still a byte-level cut and the kept frames stay untouched; when the file stores frames as small patches over the previous one, the tool composites them first and rebuilds the GIF from the frames it keeps. A GIF too large to rebuild in the browser plays as fast as the floor allows instead, and the label under the preview and the file name show the speed it really reaches.
Your GIF never leaves your device. The file is read, retimed and saved entirely inside your browser; nothing is uploaded, there is no signup and no watermark, and once the page is open the tool even works offline.
Open the GIF, drag the speed slider to the right - it settles on 2x as you pass it - and watch the preview play at the new speed. Press download and the retimed GIF is saved - the frames themselves are untouched, only their timing changes.
The same slider goes the other way: 0.5x plays at half speed and 0.25x at quarter speed, which works as a slow-motion effect. The frame count stays the same, so slowing down never makes a GIF choppier than it already was.
No, not here. The tool rewrites only the per-frame timing values inside the file, so every pixel, color palette and frame comes out byte-identical to the original. Nothing is decoded, re-encoded or recompressed. The one exception is a speed-up past the GIF speed limit on a file that stores its frames as patches: there the frames that stay are rebuilt, as explained above.
Browsers refuse frame delays shorter than 2 hundredths of a second, so past that floor the only way to go faster is to show fewer frames. The tool keeps every frame it can and drops the rest evenly, so the motion stays smooth. Slowing down never drops anything.
No. The file is read, retimed and saved entirely in your browser - nothing is transmitted anywhere, and the tool keeps working even offline once the page is open.
