How to Crop a PDF to Remove White Margins — Free Online

PDFs with large white margins — common with scanned documents or academic papers — can be cropped to make content larger and more readable.

1

Open pdfeditor.onl/crop-pdf

Navigate to the crop tool and upload your PDF.

2

Set Crop Values

Enter crop values for top, bottom, left, and right margins. Start with 30–40pt on each side for typical over-margined PDFs. Preview the result before applying.

Tip: Check the preview at 100% zoom before applying — over-cropping removes actual document content. For scanned documents, leave at least 10pt margin on all sides.

Frequently Asked Questions

Does cropping remove the hidden content or just hide it?

PDF cropping sets the crop box — content outside the crop box is hidden but technically still in the file. Use flattening after cropping to permanently remove it.

Is this free?

Yes — completely free at pdfeditor.onl/crop-pdf.
