Clean up ugly scan borders
Scanned PDFs often contain black edges, skewed borders, or too much white space. Cropping those margins makes the file easier to read and more professional when shared, printed, or archived.
Use cropping after scanning
Open the scan in the crop tool, define the visible area you want to keep, and apply the trim to one page or all pages. This is especially useful for copied contracts, receipts, and official records.
Combine with other cleanup steps
After cropping, many users rotate misaligned pages, compress the file for email, or run OCR to make a scanned document searchable.
