GIF Speed Changer
Change how quickly the animation plays by adjusting frame delays. The image frames stay the same; only their timing changes.
Continue with the file you are working on.
Browser-first GIF processing.
GifShaper reads your file on this device, decodes the animation, applies the selected change, and rebuilds a new output. The source file is not sent to a conversion server by the tool.
GIF is a palette-based animation format, so rebuilding can slightly change colors. Use 256 colors when visual detail matters most, or fewer colors when file size matters more.
Built for ordinary web GIFs.
- GIF inputs are capped at 50 MB.
- Very large frame counts can use substantial browser memory.
- Processing speed depends on your device.
- Keep the tab open until the output is finished.
Before you process.
How do you speed up a GIF?
The tool shortens each frame delay. Slowing down does the opposite.
Will changing speed change dimensions?
No. Width and height remain unchanged on this page.
Why do very fast GIFs look capped?
Many GIF viewers impose a practical minimum frame delay. GifShaper keeps delays at or above 20 milliseconds for compatibility.
