Resize GIF Online
Set new pixel dimensions for an animated GIF. GifShaper resizes every frame and rebuilds the animation locally.
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.
Does resizing keep the GIF animated?
Yes. Every decoded frame is resized and encoded back into one animated GIF.
Can I make a GIF larger?
Yes, within the 2400 px output limit. Enlarging can look soft because it cannot create detail that was not in the original.
Does the file stay private?
Yes. The file is processed in your browser and is not uploaded by the tool.
