Question 1

Does resizing a GIF keep the animation?

Accepted Answer

Yes. This tool decodes every frame of the GIF, resizes each frame to the new dimensions, and re-encodes them into a new animated GIF with the same timing and loop.

Question 2

Is my GIF uploaded to a server?

Accepted Answer

No. All decoding, resizing and encoding happens entirely in your browser using the WebCodecs and Canvas APIs. Your file never leaves your device.

Question 3

What is the maximum GIF size I can resize?

Accepted Answer

Most browsers handle GIFs up to roughly 50MB and a few hundred frames. Very large GIFs may be slow or run out of memory — try resizing in smaller steps.

Question 4

Can I resize a GIF to an exact pixel size?

Accepted Answer

Yes. Enter the exact target width and height in pixels, or use the percentage slider. With 'keep aspect ratio' on, the height auto-updates to match the width.
