GIF Speed Changer

Make a GIF faster or slower without losing any quality. Pick a speed like 2× or 0.5×, or set one frame delay for the whole animation, and compare the new speed with the old side by side. Free and instant, in your browser.

A GIF that crawls makes a reaction fall flat; one that races past is impossible to follow. Changing the speed usually means re-encoding the whole animation, which costs quality and time.

This GIF speed changer does not re-encode. A GIF stores each frame's timing in a few bytes separate from its pictures, so it rewrites only those bytes: every frame stays exactly as it was, and even a large GIF is done in a moment. Only when you ask for more speed than browsers can play are frames merged, and the tool says so before you start.

How to change the speed of a GIF

  1. Add your GIF

    Drop an animated GIF on the box above or choose one. Its frame count and the length of one loop appear under the preview.

  2. Choose the new speed

    Drag the slider or tap a preset: 2× plays twice as fast, 0.5× half as fast. Or switch to Frame delay and give every frame the same timing.

  3. Set the loop if you want

    Keep the loop as it is, make the GIF repeat forever, or have it play once and stop.

  4. Apply and compare

    Press Change speed. The original and the new version play side by side, with the length of each loop, so you can check before downloading.

Speed up a GIF, or slow it down

Speed works like a playback rate. At 2× every frame is shown for half as long, so the loop takes half the time; at 0.5× each frame lasts twice as long. Frames that were meant to linger, such as a pause on a punchline, keep that pause in proportion.

Slowing down is always lossless here. Speeding up is lossless too, until frames would need to be shown for less than 20 milliseconds.

Why GIFs have a speed limit

GIF stores delays in hundredths of a second, and browsers treat the shortest ones, 0 or 10 milliseconds, as a mistake: they slow those frames down to about 100 milliseconds. Speed a GIF up too far and it ends up slower than before.

This tool never writes a delay browsers will not honor. When the speed you ask for would need frames shorter than 20 milliseconds, neighboring frames are merged instead, so the GIF really does play at the new speed. The action bar says when this will happen, and the result shows how many frames were kept.

Set the same delay for every frame

Some GIFs have uneven timing: a stutter where one frame lingers, or a slideshow with random pauses. Frame delay mode gives every frame the same duration, from 20 milliseconds (50 frames per second) to a minute. The GIF splitter shows every frame’s delay, so you can see where the timing jumps.

100 milliseconds (10 frames per second) is a common, smooth choice for animation; 500 to 1,000 milliseconds suits a slideshow of photos. To change one frame's timing rather than all of them, use the GIF maker, which lets you set each frame on its own.

Change how many times it loops

A GIF can loop forever, play once and stop on its last frame, or repeat a set number of times. Choose Forever for chat reactions, or Play once for an animation that should end on its final image, such as in a slide or an email.

Changing the loop is lossless as well: it is another small block of bytes in the file. If the GIF is headed for a video platform, convert it to MP4 after changing the speed.

When people change GIF speed

  • Reactions that land

    Speed up a slow reaction so the moment hits, or slow down a fast one so it can be read.

  • Readable tutorials

    Slow down a screen-recording GIF so each step is visible before the next one starts.

  • Product demos

    Tighten a demo loop so the whole feature fits in a few seconds on a landing page.

  • Slideshows

    Give every photo in a GIF slideshow the same, longer time on screen.

  • Smoother animation

    Even out a stuttering GIF by setting one delay for every frame.

  • Emails and slides

    Make an animation play once and stop, so it does not loop distractingly beside text.

Frequently asked questions

Does changing the speed reduce quality?
No. Only the frame delays are rewritten; every pixel stays exactly the same. The one exception is speeding up beyond what browsers play, where neighboring frames are merged, and the tool tells you first.
How do I make a GIF faster?
Add the GIF and choose a speed above 1×, for example 2×. The loop takes half as long.
How do I slow down a GIF?
Choose a speed below 1×: 0.5× plays at half speed, 0.25× at a quarter. Slowing down is always lossless.
What is the fastest a GIF can play?
About 50 frames per second, or 20 milliseconds a frame. Browsers slow down shorter delays, so faster speeds are reached by merging frames instead.
Does the file size change?
Barely, when only the timing changes. When frames are merged, the file usually gets smaller, because there are fewer frames.
Can I make a GIF stop looping?
Yes. Under Loop, choose Play once. Choose Forever to make it repeat endlessly.
Is my GIF uploaded?
No. The timing is changed in your browser, on your device.
Can I change the speed of a video instead?
This tool works on GIFs. To make a GIF from a video at the speed you want, use the GIF maker and choose the frames per second.
