About this tool
Adjust how fast an animated GIF plays by scaling the delay of every frame. Speeding up is perfect for GIFs recorded from screen captures that drag, or for making a reaction snappier; slowing down helps show a step-by-step process.
GIF frame delays are stored in hundredths of a second and browsers refuse to show a frame for less than about 20 ms, so extreme speed-ups on already-fast GIFs are capped by the format. For a big speed-up on a smooth GIF, convert it to video first, where frame rate is unlimited.
How to use it
- Drop your GIF files into the box above, or click to browse. Nothing is uploaded.
- Adjust the options if you want; the defaults suit most files.
- Click the button and wait a moment.
- Download the results individually or all at once as a ZIP.
Questions
Why does 4× not look four times faster?
Browsers enforce a minimum frame delay of roughly 20 ms. If the GIF already plays at 50 fps, it cannot go faster without dropping frames.
Are frames removed when speeding up?
No. All frames are kept; only the display time of each frame changes, so the file size stays about the same.
Is it free, are files uploaded, which browsers work: the general questions are answered once for the whole site.
