Crop Image

About the Image Cropper

This trims an image down to the part you want — dragging a box over the photo and cutting away the rest. Use it to straighten up a composition, remove unwanted edges or people, make a square profile picture, or produce the exact aspect ratio a platform needs (a 1:1 avatar, a 16:9 thumbnail, a 4:5 portrait post). Drag to position and resize the crop box, and download the cropped result at full resolution.

How it works

The image is shown scaled to fit, with a draggable, resizable crop box over it. You can crop freeform (any rectangle) or lock the box to a preset ratio — 1:1, 16:9, 4:5 or 3:2 — so it keeps those proportions as you resize. A live readout shows the crop's pixel dimensions. When you download, the tool maps your on-screen box back to the image's full resolution and exports exactly that region, so you get the original quality of the cropped area, not the scaled-down preview.

Assumptions and behaviour

• Freeform and preset ratios (1:1, 16:9, 4:5, 3:2) are available; the ratio lock keeps proportions while you resize.
• The crop is taken at the image's native resolution, so quality within the cropped area is preserved.
• The dimension readout reflects the actual output pixel size, not the preview size.
• The crop box is constrained to stay within the image bounds.

Limitations

• Cropping is a rectangular cut only — it doesn't do circular/rounded crops, free-shape masking, or rotate-while-cropping (use Rotate first if the shot is tilted).
• It removes pixels; it can't extend the canvas or add background around an image.
• Cropping reduces the pixel count, so a heavily-cropped small image will be low-resolution — there's no upscaling to compensate.
• It crops one image at a time.
