GIF Speed Changer
Drop a GIF and pick a speed from 0.25× (four times slower) to 3× (three times faster); the preview plays the new speed straight away. Speed scales every frame's own delay, so uneven timing in the original stays uneven in the right places. You can also cap the frame rate to make the file smaller, reverse it or set how many times it loops. Nothing is uploaded.

Drop a GIF here

Processed on your device. Nothing is uploaded.
How it works
- 1. Drop, paste or pick an animated GIF (or animated WebP or AVIF) up to 100 MB. It's decoded in your browser with every frame's own timing; nothing is uploaded.
- 2. In Timing, choose a speed from 0.25× to 3× and watch the preview. Lower the frame rate to shrink the file, or set the loop count.
- 3. Open Export, keep GIF or switch to WebP, MP4 or AVIF, optionally set a size limit to fit, then download. The before/after view shows the original next to the result.
Recommended settings
| Use case | Settings | Why |
|---|---|---|
| Slow motion | Speed 0.5× or 0.25× | Each frame is shown two or four times as long; no frames are invented, so very slow speeds look steppy. |
| Snappier reaction GIF | Speed 1.5×–2× | Faster playback suits short loops; the file size stays about the same because the frames are the same. |
| Smaller file at the same speed | Speed 1×, frame rate 10–15 fps | Dropping frames keeps the length but stores fewer pictures, which is what actually shrinks a GIF. |

Questions about GIF Speed Changer
- How do I make a GIF faster or slower?
- Drop it in and change Speed under Timing. 2× halves every frame's display time so it plays twice as fast; 0.5× doubles it. The preview updates immediately, and the exported GIF plays at that speed everywhere.
- Why doesn't my GIF get any faster above a certain speed?
- Most browsers show GIF frames with a delay of 10 ms or less at 100 ms, which would make a 'very fast' GIF play slowly, so Framimo never writes a delay under 20 ms (50 frames a second). A GIF that already runs near that can't go faster frame by frame. Lower the frame rate first: fewer frames each get a longer delay, which the speed setting can then shorten.
- Does changing the speed change the file size?
- Barely: the same frames are stored with different delays. To make a GIF smaller, lower the frame rate (it drops frames but keeps the length) or reduce its width; the Export tab shows the estimated size before you download.
- What is the difference between speed and frame rate?
- Speed changes how long the whole animation takes. Frame rate controls how many distinct pictures are shown per second: lowering it drops frames and gives their time to their neighbours, so the clip keeps its length but plays less smoothly.
- Is my GIF uploaded anywhere?
- No. The GIF is decoded, edited and re-encoded by background workers in your browser tab. Nothing is sent to a server, there is no signup and no watermark, and it keeps working if you go offline after the page loads.
- How big a GIF can I edit?
- Files up to 100 MB are accepted and every frame keeps its own timing. Only an extremely long, large GIF can run past what your device can hold in memory; then the editor keeps as many frames as fit and tells you so.
- Can I save the result as MP4 or WebP instead of GIF?
- Yes. The Export tab offers GIF, animated WebP, MP4 and AVIF from the same edit, with an estimated size for each, so you can pick the smallest one your destination accepts.
How GIF timing works
Each GIF frame carries its own delay in hundredths of a second, so a GIF has no single frame rate: a pause can be one frame held for two seconds. Changing the speed divides every delay by the same factor, which keeps those holds and pauses in proportion.
Because delays are stored in hundredths of a second, a sped-up delay is rounded to the nearest 10 ms, and the rounding is carried over so the total length stays accurate. Delays are never written below 20 ms, the shortest that browsers reliably honour; for more speed than that, lower the frame rate as well.
Slow motion without stutter
Slowing a GIF down doesn't create new in-between frames; each frame is just shown longer. 0.5× usually still looks smooth; 0.25× on a GIF that was only 10 frames per second will look like a slideshow. For smooth slow motion, start from the source video instead and use Video to GIF with a higher frame rate.
Private by design
Framimo converts your files inside your browser tab, so your GIF is never sent to a server for this GIF export. There is no signup and no watermark, and you can disconnect from the internet once the page has loaded.
