GIF
Max file size: 16 MiB
Exact dimensions
Enter a width, a height or both, from 1 to 4,096 pixels. With one value, the other is calculated to keep the proportions. With both, every frame is stretched to exactly that size.
Playback is preserved
Every frame is resized, and the original frame timing, loop count and transparency are kept, so the animation plays the same way at its new size.
Preview and compare
The result shows the new pixel size with the original and new file sizes, and an animation preview you can open before downloading.

What people use this tool for
- Shrink a screen recording GIF to fit the width of a README, a help article or an email.

- Cut the file size of a large GIF by reducing its dimensions before compressing it.
- Enlarge a small pixel-art animation for a presentation slide.
Frequently Asked Questions
How do I resize a GIF without stretching it?
Set only the width or only the height. The page starts with a width of 480 and the height blank, which keeps the proportions: a 640 × 480 GIF becomes 480 × 360. To scale by height instead, clear the width field and enter a height.
Can I make the GIF square or an exact size?
Enter both the width and the height. Every frame is stretched to those dimensions, so a wide GIF forced into a square looks squeezed. The resizer does not crop the picture or add borders. To keep the proportions, set one dimension only.
Can I make a GIF larger?
Yes, up to 4,096 pixels per side, as long as the result stays within 16 million pixels across all frames. Enlarging cannot add detail: the picture becomes softer and the file much bigger. It is mainly useful for small pixel-art or icon animations that have to fill a larger space.
Does resizing reduce the file size?
Usually. Halving the width and height leaves a quarter of the pixels in each frame, and the file normally shrinks a great deal. The result shows the real before and after sizes. If it is still too large, run the resized GIF through GIF Compressor to reduce the color palette as well.
Will the animation still loop and keep its speed?
Yes. Frame delays and the loop count are copied from the original, including animations that play a set number of times, and transparent areas remain transparent. Each frame is re-encoded with a palette of up to 256 colors and dithering, so fine gradients can look slightly different from the source.
What are the limits, and why was my GIF rejected?
The upload must be a real GIF of up to 16 MiB, 4,096 pixels per side and 300 frames, with at most 16 million pixels across all frames. That pixel limit applies to the resized animation too. A file renamed from another format, or a download that was cut short, is refused as invalid. Processing has to finish within one minute.
How is this different from Image Resizer?
Image Resizer handles still images and resizes only the first frame of an animation, so a GIF comes out as a single picture. This tool resizes every frame and writes an animated GIF. It has no crop, pad or percentage modes: you set the size in pixels.
Where is the GIF processed, and when is it deleted?
On Zutilium's server, so the GIF is uploaded when you convert. After a successful conversion the upload is scheduled for deletion after about one minute and the result after about ten minutes. Cleanup runs once a minute, so removal is not instant. Download the resized GIF promptly.
