A GIF plays at whatever pace its maker chose, and that is often wrong for a new purpose. A screen recording crawls, a sports clip passes too quickly to follow. This page opens the GIF editor at double speed. Add the animation and pick a pace from 0.25× to 4×. The preview plays at the new speed and shows the new length.
Changing speed does not add or remove pictures. Every frame of a GIF carries a number saying how long it stays on screen, and only those numbers are altered. At 2×, each frame is shown for half as long. The file therefore stays about the same size; a faster GIF is shorter in time, not lighter in bytes.
There is a floor. Browsers do not display a frame for less than about two hundredths of a second, and a shorter value is treated as a much longer one, which makes a GIF that was meant to be fast play slowly. Frame times are never set below that floor here. A GIF that is already quick may reach it before 4×.
Speeding up
A faster GIF suits demonstrations and time-lapses, where the viewer wants the outline of what happened. Screen recordings of someone clicking through a form are usually better at 1.5× or 2×. If the frames are already short, combine speed with keeping every second frame: half the pictures, each shown as long as the pair it replaces, then sped up. That lowers the file size as well.
Slowing down
Slow motion draws attention to a detail: the moment of impact, a facial expression, a trick. Because no new frames are invented, a GIF slowed to half speed shows the same pictures for twice as long, and movement looks steppy when the original had few frames. A GIF recorded at twenty or more frames a second slows gracefully. One recorded at eight will look like a slideshow at a quarter speed.
For a smoother slow motion, go back to the source video and export the GIF again at a higher frame rate.
Speed and the loop
Speed changes how soon the loop comes round. A two second GIF at double speed repeats every second, which can turn a calm animation into a nervous one. Watch a few rounds in the preview. Trimming and speed work together here: a slightly longer piece at a higher speed often reads better than a short piece at the original pace.
Per-frame timing is respected
Many GIFs hold some frames longer than others, a pause on the final frame for example. The change is proportional. A frame held for a second lasts half a second at 2×, and a frame held for a tenth lasts a twentieth, so the rhythm of the original survives at any speed.
Frequently asked questions
Does changing speed reduce the file size?
No. The same frames are stored, with different timing. Dropping frames or resizing reduces the size.
How fast can a GIF go?
Up to four times its speed, as long as no frame falls below two hundredths of a second, the shortest time browsers honour.
Why does my slowed GIF look jerky?
Slowing shows each existing frame for longer; it does not create frames in between. A source with few frames cannot become smooth slow motion.
Can I choose a speed that is not in the list?
The editor offers seven steps. The API's speed parameter takes any whole percentage from 25 to 400.
Is the quality affected?
The pictures are encoded again as a GIF, which changes little. The timing change itself does not touch the pixels.
Can I speed up only part of a GIF?
No. The speed applies to the whole animation, or to the part kept by Trim.
