Frequently asked questions
Is cropping reversible?+
Cropping sets a CropBox in the PDF — original content is technically still present. Open the file in Adobe Acrobat Reader and remove the CropBox to restore margins.
Will cropping affect print layout?+
Yes — the reduced page area will print with smaller margins. Ensure the new crop boundaries still leave adequate whitespace for printing.
Can I preview the crop before downloading?+
Process the file and preview in your PDF viewer before distributing — re-upload and adjust if needed.
