How GIF Speed Adjustment Works

Every animated GIF stores a delay value between frames, measured in centiseconds (hundredths of a second). A delay of 10cs produces 100ms per frame. The GIF Speed Changer reads the original delay from your GIF using ImageMagick, applies the chosen multiplier or custom value, and writes all frames with the new timing. A 2× preset halves the delay to double the playback speed; a 0.5× preset doubles it to halve the speed. Pixel data, color palettes, and loop count are untouched.

Frequently asked questions

How does changing GIF speed work?

GIF animation speed is controlled by the delay between frames, measured in centiseconds (1/100 second). The GIF Speed Changer reads your GIF’s original per-frame delay, calculates a new delay based on your chosen multiplier, and rebuilds the GIF with the new timing applied uniformly to all frames.

What does the 2× speed preset do?

The 2× preset halves the inter-frame delay. If your GIF originally shows each frame for 10 centiseconds (100ms), the 2× version shows each frame for 5 centiseconds (50ms), making the animation play twice as fast.

What is the custom delay option for?

Custom delay lets you set an exact milliseconds-per-frame value (10–500ms) instead of a multiplier. Use this when you need a specific playback speed — for example, 33ms per frame produces approximately 30fps playback, and 41ms produces approximately 24fps. Typical web GIFs use 50–150ms per frame.

Will changing the speed affect GIF quality?

No. Only the inter-frame timing values are modified. Pixel data, color palette, frame count, and loop count are all preserved exactly. The output GIF is pixel-identical to the input in every visible frame.

What is the maximum file size?

You can upload GIFs up to 20 MB. Files are removed from the server within 30 minutes of processing.

How to change animated GIF speed online

  1. Click the upload zone or drag your animated GIF into it. Maximum file size is 20 MB.

  2. Select a speed multiplier — 0.25× (very slow) through 4× (very fast) — or choose Custom and enter a frame delay in milliseconds. Default is 2×.

  3. Click Change Speed and wait a few seconds for server-side processing.

  4. Preview the result and click Download GIF to save your speed-adjusted file.
