Make an animated GIF faster or slower in seconds. Pick a speed such as 2× or 0.5×, set the same delay for every frame, or edit each frame's delay individually, and change how many times it loops. Only the timing is rewritten, so the frames keep their exact original quality.

How to use the GIF Speed Changer
Add your GIF: drop it on the box, paste it, or press Choose GIF. A sample animation is loaded so you can try it first.
Choose the new speed: tap a preset such as 2× or 0.5×, drag the slider, set a fixed delay, or edit the delay of single frames in the Per frame tab.
Set the loop if needed: keep the original, loop forever, play once or a set number of times.
Compare the original and new animation side by side.
Download the new GIF.
How GIF speed works
An animated GIF has no single frame rate. Each frame carries its own delay in its Graphic Control Extension, stored as a whole number of hundredths of a second (10 ms units). The animation's speed is simply the sum of these delays:
New delay = original delay ÷ speed (2× halves every delay, 0.5× doubles it)
Frames per second = 1000 ÷ delay in ms
Loop length = sum of all frame delays
Because delays must be whole 10 ms steps, the tool carries each rounding error over to the next frame. A 2.5× speed on 100 ms frames becomes 40, 40, 40… ms exactly, and 30 fps becomes an alternating 30 ms / 40 ms pattern that averages 33.3 ms.

The 20 ms limit and dropping frames
Chrome, Firefox, Safari and most apps treat a delay of 0 or 10 ms as "too fast" and play it at 100 ms instead, so a GIF made "faster" that way actually becomes slower. This tool never writes delays below 20 ms. If you ask for more speed than that allows, you can enable Drop frames: consecutive frames are grouped until each group lasts at least 20 ms and only the first frame of each group is kept. That needs a new encoding with a 256-color palette, while normal speed changes keep the original file data untouched.
Frequently asked questions
How do I speed up a GIF?
Add the GIF, choose a speed above 1× such as 1.5× or 2× and press Download GIF. Every frame delay is divided by the speed, so 2× halves each delay and the animation plays twice as fast.
Does changing the speed reduce the quality?
No. In normal use the tool only rewrites the delay value stored in each frame's Graphic Control Extension. The image data, colors and transparency are copied byte for byte, so quality is identical and the file size barely changes.
Why won't my GIF play any faster?
GIF delays are stored in hundredths of a second, and browsers treat delays below 20 ms (0.02 s) as 100 ms, which would make the GIF slower instead of faster. The tool never writes delays below 20 ms. To go faster than that, turn on Drop frames: some frames are skipped and their time is given to the frames that remain, which re-encodes the GIF.
What is the frame delay of a GIF?
Each frame stores how long it stays on screen in units of 10 milliseconds. A delay of 10 means 100 ms, or 10 frames per second. Different frames can have different delays, which is why the Per frame tab lets you edit them one by one.
How do I convert a delay to frames per second?
Frames per second = 1000 ÷ delay in milliseconds. For example 50 ms is 20 fps, 40 ms is 25 fps and 100 ms is 10 fps. Because delays are whole hundredths of a second, exact 24 or 30 fps is not possible; the tool alternates values (for example 30 and 40 ms) so the average is right.
Can I change how many times the GIF loops?
Yes. Choose Loop forever, Play once, or Play N times. The loop count is stored in the NETSCAPE2.0 application extension, which all modern browsers and chat apps respect.
Is my GIF uploaded?
No. The GIF is read, changed and saved entirely in your browser, so it stays private and the tool works offline once loaded.
Are all the tools on FreeToolCabin tested for quality and accuracy?
Yes! Every tool on our site undergoes automated Q/A testing in real browser environments to ensure high precision, correct output, and zero errors. If you happen to spot a bug or have a suggestion, please contact us at [email protected] and our team will review it right away.
