About this tool
This page opens the image cropper with the 1:1 square aspect ratio already selected — drop in your photo, position the frame and download the crop.
A square crop keeps width and height identical — the standard shape for profile pictures, avatars, Instagram-style grids and product thumbnails. Because the ratio is locked, the frame stays a perfect square however you drag or resize it.
Need a different shape? The full tool also offers 4:3, 16:9 and a free-form frame. Everything runs locally in your browser, so your photos never leave your device.
Example. A selection rectangle is copied to a new canvas and downloaded as the cropped image.
Limit. The crop is always an axis-aligned rectangle; a freehand outline is not a crop path.
