Drag a box, hold it to a shape, and say how many pixels you want out. Nothing is sent anywhere unless you ask for it.
Drop an image here
Or click to choose one. Pasting works too.

How many pixels come out
Asking for more pixels than the crop has will not add detail that was never there.
This picture has see-through parts and JPEG cannot keep them.

Drag inside the box to move it, a corner or edge to resize it, or anywhere outside to start a new one. Everything outside the box is what gets cut away.
