GIF speed changer

Speed up or slow down a GIF by scaling every frame's delay, or set one fixed delay.

Decoded, re-timed and re-encoded in this browser — the GIF never leaves your device.

Input up to 25 MiB. Output uses the shared encoder's envelope: 640×640px, 120 frames, minimum 2 cs per frame. Re-encoding re-quantizes to 256 colors — very small delay changes can still move the file size a lot.

How to use

  1. Choose a GIF.
  2. Pick a speed factor or a fixed frame delay.
  3. Re-encode and download.

What it supports

Input up to 25 MiB; output is re-encoded within the shared encoder envelope (640×640, 120 frames, 256-color palette). Re-quantization can change file size noticeably.
