Why Resize GIF?
Every platform has its own size rules — chat avatars, forum signatures, embedded demos and email all cap dimensions or file weight. Resizing a GIF means rescaling every single frame, and this tool does exactly that: each frame is redrawn at the new size and the animation is re-encoded with its original timing, so motion stays smooth. Enter just a width or height to keep proportions automatically. Everything runs in your browser, so GIFs never leave your device.
Every Frame Rescaled
The whole animation is resized, not just the first frame.
Ratio Aware
Enter one dimension and the other is calculated to keep proportions.
Private & Free
Runs locally in your browser, free and with no signup.

Frequently Asked Questions
Everything you need to know about resize gif.
Yes. Every frame is rescaled and the animation is preserved.
Enter only a width or only a height and the other is computed automatically.
No. Resizing runs entirely in your browser.
Usually a lot. File size scales with pixel area, so halving the width and height can cut the size to roughly a quarter.
Yes, though upscaling cannot add detail — frames are scaled up smoothly but may look softer than the original.
No. Frame delays are copied over exactly, so the resized GIF plays at the same speed as the original.
