Page guide

Keep one rectangle from an animated GIF. Crop every frame without losing its timing.

How to use Crop GIF
  1. Upload a GIF. Enter the left and top offsets, then the width and height of the crop in pixels. The rectangle must fit inside the original image. Run the tool, preview the result and download it.
  2. The same rectangle is applied to every composited frame. The animation keeps its frame order, timing and loop count. Cropping removes content outside the rectangle from the output.
