How to use it
- Drop your GIF here.
- Pick a multiplier (0.25×–4×), or enter one delay for every frame in milliseconds.
- Click Change speed and download.
Multiplier or fixed delay
A multiplier scales every frame's delay: 2× is twice as fast, 0.5× half as fast. The original rhythm (a longer pause at the end, say) is preserved. A fixed delay gives every frame the same time, for example 100 ms (10 frames per second); that smooths out jerky, uneven GIFs.
The new length updates as you change the setting.
The 20 ms limit
GIFs store delays in hundredths of a second, and browsers slow down anything under 20 ms, often to 100 ms. So the minimum is 20 ms, about 50 frames per second. For an even faster effect, drop frames: split the GIF and build a new one from fewer frames.
The GIF is processed in your browser, never uploaded, and gets no watermark.
Frequently asked questions
Can I slow a GIF down?
Yes, with 0.75×, 0.5× or 0.25×, or a longer fixed delay.
Does the file size change?
Practically not, since the number of frames stays the same.
Why doesn't 4× make it faster?
If the frames are already short, the 20 ms limit stops further speed-up.
