DETAILS

Detect and crop white scan margins

Each page is rendered locally, dark-pixel boundaries are detected, and the PDF CropBox is adjusted with your chosen padding.

Example

Crop an A4 scan containing a small receipt down to the receipt plus a 5 mm margin.

Good to know

Colored paper, shadows, holes, or edge marks can affect detection. Inspect the exported PDF.

Frequently asked questions
