GIF speed changer online

Speed up GIF or slow down animated GIF online free. Change GIF speed with a frame-delay slider—preview and download in your browser.

What is a GIF speed changer?

A GIF speed changer adjusts how fast an animated GIF plays by rewriting frame delay—the pause between frames. People search for speed up gif, gif speed up, slow down gif, gif slow down, change gif speed, or animated gif speed when a loop feels too sluggish or too frantic. Lower delay speeds the animation up; higher delay slows it down. This free online tool applies one delay to every frame, then lets you preview and download. It does not stretch or upscale the GIF, cut frames (use /gif-cutter or /shorten-gif), or act as a full animated GIF editor for drawing and filters.

Tips for GIF speed editing

Get better results when speeding up or slowing down GIFs.
  • 01

    Start near original timing

    Default 0.10s is a common starting point—nudge from there.

  • 02

    Very fast can look choppy

    0.02s works for short loops; long GIFs may need slightly higher delay.

  • 03

    Slow motion needs patience

    2.0s per frame suits title cards; action clips often need 0.3–0.8s.

  • 04

    Not frame interpolation

    This changes timing only—it does not add blended in-between frames.

  • 05

    Trim separately

    To shorten length without changing speed, use /shorten-gif.

  • 06

    Combine clips elsewhere

    To chain multiple GIFs after speeding, use /gif-combiner.

    Speed up or slow down GIFs with no signup; processing stays on your device.

  • One clear control

    A single frame-delay slider changes GIF speed for every frame.

  • Preserves transparency

    Alpha channels kept through decode and encode.

  • No install

    Works in any modern browser on desktop or mobile.

  • Instant preview

    Check animated GIF speed before exporting.

  • Pairs with other GIF tools

    Combine with /shorten-gif, /reverse-gif, or /gif-resizer when needed.

Technical details

How client-side GIF speed change works.
GIF decode
gifuct-js decompresses frames with full image patches and transparency.
Uniform delay
Every frame receives the same delay in milliseconds (20–2000 ms).
GIF encode
gifenc quantizes RGBA frames and writes loop metadata when present.
Canvas size
Output matches the original GIF logical screen dimensions.
Input format
Animated GIF only (.gif).
Limits
15 MB max upload; large frame counts depend on browser memory.
