How to Crop PDFs Before Printing to Save Paper and Ink

TL;DR

Cropping margins lets content fill the sheet when you print with Fit to Page, so text is bigger and you can print smaller. It does not reduce ink by itself, but it removes scanner borders. Print directly from the exported file in PDFCrop.

The problem

You print lecture notes or a scanned paper and half the sheet is empty border, so the text is small. Scanners also add dark edges and shadow bands that print as solid grey. Reprinting to fix that costs paper.

Steps

  1. Import the PDF and crop away the border. Leave 3–5 mm of white around the content.
  2. Apply the crop to all pages if they match.
  3. Export.
  4. In Files, open the exported PDF and tap Print.
  5. Choose your printer and in the iOS print options leave Fit to page on, which makes the cropped content fill the sheet.

What you gain

  • Larger text at the same paper size.
  • No more dark scanner edges or shadows, which print as ink.
  • Pages that don’t get clipped by the printer’s non-printable zone, as long as you leave a margin.

What you don’t gain

  • Cropping does not remove content hidden under the crop from the file.
  • The page size changes, so check the print preview to see the real scale.
  • It’s not a layout tool: no n-up or booklet printing.

Tip

Print one page as a test before a 100-page run.

FAQ

Does cropping reduce ink use? Only if the removed area was printed (like dark scanner edges or a grey background). White margins use no ink; the saving is paper and legibility.

Can I print from PDFCrop? Yes. Open the exported file in Files and use Print.

Why are my printed edges cut off? Many printers cannot print right to the edge. Leave a little margin in the crop.

Can I put two pages on one sheet? Not in PDFCrop. Use the iOS print dialog’s layout options if available.
