How the Processing Engine Works
Cropping extracts a designated coordinate window (x, y, width, height) from the source image. Trimming excess border areas also reduces overall pixel count and final file weight.
Balancing Quality, Dimensions & Target Size
Cropping permanently removes pixel data outside the selection box. Our tool always operates non-destructively in memory, allowing you to reposition the crop box until you are completely satisfied.
