Change GIF Speed

Speed up or slow down an animated GIF without re-recording anything — free, entirely on your device.

How GIF speed adjustment works

Each frame of a GIF carries its own display duration. This tool multiplies every frame's delay by the inverse of your chosen speed — set it to 200% and each frame shows for half as long, making the whole animation play twice as fast; set it to 50% and every frame lingers twice as long for a slow-motion feel.

No frames are added or removed, so the sequence of events stays identical — only the pacing changes.

When to speed up or slow down

Speeding a GIF up — anywhere from 150% to 400% — is the usual fix for a screen recording that captured too much dead time, like someone waiting for a page to load between clicks. It compresses the boring parts without editing anything by hand. Slowing a GIF down, from 25% to 75%, is more often used for comedic timing, to make a subtle motion easier to notice, or to give a tutorial-style GIF enough time to actually read on screen.

A useful habit is checking the result at normal viewing size rather than judging it while zoomed in on the editor — pacing that feels slow while you're staring closely at a slider often looks completely natural once the GIF is embedded at its real size in a chat or web page.

The math behind the slider

Every frame in a GIF stores its own delay value — the number of milliseconds it stays on screen before the next frame appears. Setting the speed slider to 200% divides every frame's delay by two, so the whole animation plays back in half the time; setting it to 50% doubles every delay, stretching the same sequence out to twice its original length. No frames are duplicated or removed at any setting — only the timing between them changes.

This calculation, along with the decoding and re-encoding it requires, happens entirely inside your browser tab using a WebAssembly-based GIF engine — your file is never transmitted to a server at any point.
