GIF speed changer
Rewrites real frame delays — the downloaded GIF itself plays faster, not just the preview.
- Data never uploads to a server
- Free, no sign-up, no watermark
- Runs offline after loading

Load a GIF and pick a speed.
How speed changing works
- Load. Per-frame delays are read from the file.
- Pick a multiplier. 2× halves every delay, 0.5× doubles them — rhythm is kept proportional.
- Export. Frames re-encode with the new delays; pixels are untouched.
Frequently asked questions
Does speeding up hurt quality?
No — only frame delays change; pixels are untouched.
What's the fastest possible?
Delays bottom out around 20ms (browsers clamp shorter delays anyway) — roughly 50fps max.
My GIF has uneven frame delays — what then?
Each delay is scaled proportionally, so the original rhythm is kept: slow parts stay relatively slow.
Are files uploaded?
No — everything runs locally in your browser.
