The short answer
Why use GIF Speed Changer?
A GIF that races past the punchline or drags on too long only needs its frame delays changed. Editing every delay by hand in an editor is slow.
Speed runs from 25 to 300 percent and starts at 150, which plays one and a half times as fast. Each frame's delay is divided by the speed: a 100 ms frame becomes 50 ms at 200 percent and 400 ms at 25 percent. Pauses scale with everything else, so a hold on the last frame stays in proportion. Frame count, size, and loop setting do not change.
Frames that come in with no delay at all are read as 100 ms first, a common browser convention. The 20 ms floor means fast GIFs hit a ceiling: a 25 ms GIF can only gain a little before every frame sits at 20. When that happens, Reduce GIF Frames is the way to go faster, since it halves the frames and keeps the duration.
Reduce GIF Frames lowers the frame count while keeping the length, which suits file size more than pace. Reverse GIF plays the frames backwards at their existing speed. To slow down a single moment rather than the whole loop, export the frames with Extract GIF Frames and rebuild with Images to GIF.

GIF Speed Changer tips
- 200 percent halves every delay; 50 percent doubles it.
- Delays never drop below 20 ms, which caps how fast a GIF can go.
- Frames with no delay are read as 100 ms first.
- Slowing down does not add frames, so motion can look steppy below 50 percent.
