Resize an animated GIF to exact dimensions or by a scale factor (aspect ratio lock optional). Re-encodes a new GIF, preserving delays. Pure browser-side.
Upload a GIF. Set target width/height directly, or change the Scale % (e.g. 50 = half size, 200 = double). With "Keep ratio" on, editing one dimension updates the other. Click "Resize & Encode" — every frame is resampled and re-encoded with gifenc, preserving per-frame delays. Large GIFs may take a few seconds.
