How to Use GIF Speed Changer in Three Steps

Fast, private, watermark-free GIF89a output directly inside modern desktop and mobile browsers.

1

Upload an animated GIF

Choose speed (0.25×–4×) and direction

Click a preset chip or drag the precision slider, then choose Forward, Reverse, or Ping-Pong.

3

Export GIF or looping video

Understand Browser Minimum GIF Frame Delays

GIF89a stores frame delays in hundredths of a second (centiseconds), and modern browsers clamp delays below 20 ms (2 cs) to prevent CPU spikes. GifQuill recalculates every frame delay accurately while respecting the 20 ms browser floor.

Frequently Asked Questions About GIF Speed Changer

Does changing GIF speed alter file size?

Barely—adjusting frame delay headers changes two bytes per frame, keeping file weight nearly identical unless you select Ping-Pong mode.

What is the fastest frame rate browsers display for GIFs?

Browsers honor delays down to 20 ms per frame (50 FPS); delays of 0 ms or 10 ms are typically rounded to 100 ms by browser engines, which GifQuill prevents.
