Crop PDF

Cropping a PDF trims unwanted margins, borders, or whitespace from pages, giving your document a cleaner, more professional appearance. This is common with scanned documents where the scanner adds generous margins, presentations exported with excess white space, or PDFs generated with unnecessarily large page dimensions. PDFly lets you visually select the crop area on your pages, so you see exactly what will be trimmed before the operation is applied. The cropping runs entirely in your browser.

Upload your PDF and define the crop area visually — drag the crop handles to set the exact boundaries you want to keep. The tool shows a preview of the cropped result so you can verify the margins are correct. You can apply the same crop to all pages at once for consistency, or crop individual pages with different boundaries. The crop is applied permanently to the page dimensions, reducing the visible page size to your selected area.

Cropping is a visual operation — it trims the visible area but doesn't delete the underlying content outside the crop boundary. In some cases, content outside the crop area may still be accessible in certain PDF readers, though it won't be visible during normal viewing. If you need to permanently remove hidden content, combining cropping with flattening provides the strongest assurance. Cropping is particularly useful for preparing documents for print where specific dimensions are required, or for removing scanner artifacts and margins before sharing.
