Image Cropper
About this tool
Crop away the parts of an image you do not need. Drag directly on the picture to draw a rectangular selection, then drag the box to reposition it — the darkened overlay shows exactly what will be kept. If you need pixel precision, type the X, Y, width and height values into the boxes below and the selection updates to match. This is perfect for trimming screenshots, cutting out a subject, or preparing square profile pictures.
The crop is computed against the image's true resolution and rendered with the HTML canvas API right on your device, so the output stays sharp and nothing is uploaded to any server. That keeps private photos and confidential screenshots on your machine. Files up to 20 MB are supported and the cropped region downloads as a PNG.
