GIF Speed Changer
Make a GIF play faster or slower. In lossless mode only the frame delays are rewritten, so the images stay exactly as they are and the file barely changes. Browsers do not show frames shorter than 0.02 seconds properly, so for very fast speeds the tool can drop frames instead – the animation then really plays faster everywhere.
- Files stay on your device
- No sign-up
- Free to use
Lossless mode only rewrites the frame timing, so the images stay exactly the same. Browsers show frames for at least 0.02 s; speeds that would need shorter frames are capped – choose “Drop frames” for those.
How to use GIF Speed Changer
- Drop a GIF onto the page.
- Choose the speed from 0.25× to 4×.
- Choose lossless timing or dropping frames.
- Download the re-timed GIF.

GIF Speed Changer FAQ
Why is there a speed limit?
GIF stores delays in hundredths of a second, and browsers treat delays below 0.02 s as 0.1 s – which would make the GIF slower, not faster.
What does “capped” mean?
Some frames would need a delay shorter than 0.02 s. They are set to 0.02 s; choose “Drop frames” to really reach the speed.
Is quality lost?
Not in lossless mode. Dropping frames re-encodes the GIF.
Can frames have different speeds?
Each frame’s delay is scaled by the same factor, so uneven timings stay uneven in proportion.
Is my file uploaded?
No. Everything runs in your browser.
How GIF timing works
Each frame of an animated GIF carries its own delay in a small control block, measured in hundredths of a second. A GIF at “10 frames per second” simply has a delay of 10 on every frame. Changing the speed therefore does not require touching the images at all.
Lossless mode reads the file structure, finds every frame’s control block and writes a new delay: the old value divided by the speed factor, rounded to the nearest hundredth. The pixels, colours and file size stay the same – this is the fastest and safest way to re-time a GIF.
There is one catch. For historical reasons, browsers treat very short delays – 0 or 1 hundredth – as 10 hundredths, to slow down badly made GIFs. A delay of 2 hundredths (50 frames per second) is the shortest that plays reliably. When a speed-up would go below that, the tool caps it and tells you.
For those cases, the frame-dropping mode re-times the animation with FFmpeg and keeps at most 50 frames per second, discarding frames in between. The GIF then genuinely plays at the chosen speed in every browser.
