About this tool

Crop keeps only the rectangle you draw on the preview. The result is exported as PNG so the cut is not JPEG-compressed again.

How to use

  1. Upload an image.
  2. Pick an aspect ratio or leave it free.
  3. Drag on the preview to select the area, then crop and download.

Formula and methodology

Pointer position is mapped from the displayed image to natural pixels. The canvas then copies that integer rectangle from the source.

Worked example

A 1920×1080 screenshot cropped to a 1:1 square from the centre becomes a 1080×1080 PNG.
