Changing the playback speed of a GIF animation is simple with this tool. Upload your GIF, pick a speed multiplier, and download the modified file. Everything runs in your browser -- the file is never uploaded to any server.
Screen recordings often play too fast when exported as GIFs, making them hard to follow. Slowing them down to 0.5x gives viewers time to read text and see UI interactions clearly.
Conversely, time-lapse or progress animations may benefit from a speed increase. A 2x or 4x multiplier compresses playback time without removing any frames, keeping the animation smooth.
Reaction GIFs and memes sometimes work better at non-standard speeds. A slow-motion effect at 0.25x can add dramatic emphasis, while a speed-up creates a comedic effect.
GIF files store a delay value for each frame, measured in centiseconds (hundredths of a second). A delay of 10 means the frame displays for 100 milliseconds. The total animation duration is the sum of all frame delays.
When you change the speed, this tool divides each frame's delay by the speed multiplier. At 2x speed, a 10-centisecond delay becomes 5 centiseconds, halving the playback time. At 0.5x, it doubles to 20 centiseconds.
There is a practical minimum delay of 2 centiseconds (20 milliseconds). Most browsers treat any value below this as 100ms, which would actually make the GIF slower. This tool clamps delays to the 2cs minimum and warns you when this limit is reached.
No. This tool modifies only the delay values between frames. The pixel data for each frame is preserved through re-encoding with the same color palette. There is no generation loss from adjusting the speed.
The minimum practical delay is 20 milliseconds (2 centiseconds). Browsers ignore lower values or replace them with a default of 100ms, which would make the animation appear slower than intended. This tool enforces the 20ms minimum to prevent that behavior.
File size may change slightly because the GIF is re-encoded, but the difference is usually small. Speed changes only affect delay metadata, not image data. The frame count remains identical, so the bulk of the file stays the same size.
No. All original frames are preserved regardless of the speed setting. Only the timing between frames is modified. If your source GIF has 24 frames, the output will also have 24 frames.
