Drop an animated .gif (up to 40 MB).
Type exact width/height, or scale by 25/50/75% — lock the ratio to keep proportions.
Preview the resized animation live, then download.
Upload your GIF, set a new width and height (or a scale percentage), and download. Every frame is resized and re-encoded, so the animation and loop are preserved.

Usually yes — a smaller GIF has fewer pixels per frame, so the file is lighter. The live size readout shows the new file size.
No — resizing runs entirely in your browser; your GIF never leaves your device.
