How do I crop an animated GIF to remove unwanted borders?

Upload your GIF, drag the interactive cropping box or select a preset aspect ratio (1:1 Square, 16:9 Landscape, 9:16 Story, 4:5 Portrait), and click 'Crop GIF' to re-render all frames to the new bounding box.

Does cropping a GIF reduce its file size?

Yes. Cropping out unnecessary edges and background pixels proportionally reduces the canvas area and resulting file size by 30% to 70%.

Are all frames cropped to the exact same dimensions?

Yes. The selected crop rectangle is applied consistently across every single frame in the animation sequence.

Can I enter exact pixel crop dimensions (Width and Height)?

Yes. You can manually type exact pixel coordinates (X, Y, Width, Height) or drag the visual handles on the canvas.
