Drop an animated GIF, set the speed, and watch the preview update live. Drop frames to shrink the file, reverse it, then re-export. Everything runs in your browser — nothing is uploaded.
An animated image is a sequence of frames, each shown for a set number of milliseconds. Speeding it up shortens each frame's display time; slowing it down lengthens it. This editor recalculates the timing of every frame so the motion plays back smoothly at the new pace. For large speed-ups it can also drop frames evenly while preserving the total feel, which keeps the file efficient. A minimum frame delay is enforced so the result stays playable across browsers and apps.
Slowing an animation down is useful for tutorials and reaction clips where you want viewers to catch every detail, or to stretch a short loop into a calmer, more deliberate motion. Speeding one up tightens a sluggish capture, turns a long screen recording into a snappy demo, or exaggerates motion for comic effect. Reversing playback creates rewind and boomerang-style effects from an ordinary clip.
Does changing speed lower quality?
No. The frames themselves are unchanged — only their timing is recalculated, so visual quality stays identical.
Can I make a GIF play backwards?
Yes. The reverse option flips the frame order so the animation plays end to start.
Is my file uploaded?
No. Decoding, retiming, and re-encoding all happen in your browser, so your file never leaves your device.
