GIF Speed Changer

Make any animated GIF faster or slower in your browser. From subtle frame-rate tweaks (1.2×) to dramatic slow-motion (0.

How it works

The tool decodes every frame using the browser's ImageDecoder API and keeps each frame intact. Only the per-frame delay is multiplied by the inverse of your chosen speed factor. A new GIF is then encoded with the adjusted timings and the same number of frames.

Features

  • Speed multiplier from 0.1× (very slow) to 5× (very fast)
  • Adjustable color depth (2–256 colors)
  • Side-by-side before/after preview
  • 100% local processing
  • Works in modern Chromium and Firefox browsers

Use cases

  • Slow-motion meme effects
  • Fast-forward time-lapses
  • Tutorial GIFs with adjustable pacing
  • Speeding up long demo loops for social posts
  • Calming down jittery animations for accessibility
  • Sticker pack timing fine-tuning

Tips

At the extreme low end (0.1×) GIFs may appear to barely move — perfect for ultra-slow-mo effects. At 5×, fast animations may flicker; consider 2–3× for smoother fast-forward results.
