Upload a PDF, set the percentage to trim from its stored top, right, bottom and left page edges, choose whether the crop applies to every page or only selected pages, and check the result in the local page preview before processing. PdfnMore shades the area that will fall outside the exported page frame so you can inspect the change without uploading just to preview it.

Trim PDF margins precisely
Crop PDF is useful for scan borders, uneven whitespace and repeated margins. Apply one crop setting to the whole document or enter a page selection such as 1,3,5-8 when only part of the PDF needs trimming. Pages outside the selected range stay unchanged. Use Previous and Next in the local preview to inspect pages with different sizes or rotation before you run the job.
What cropping changes in a PDF
Download and inspect the cropped PDF before replacing the source. Cropping changes the visible page box; it is not secure redaction and may leave underlying PDF content recoverable by other software. Use a true redaction workflow when information must be removed rather than merely hidden from the page frame.
Each stored PDF edge accepts 0–40%. One crop setting can be applied to all pages or a selected page/range. Selected pages share the same crop percentages; separate crop boxes per page, draggable freehand crop rectangles, automatic white-margin trimming and secure redaction are not live. On pages carrying PDF rotation metadata, the local preview maps stored edges to the visible sides so the preview matches the current export behavior.
Frequently asked questions about Crop PDF
Can I preview the PDF crop before processing?
Yes. After selecting a PDF, PdfnMore renders pages locally in your browser and shades the portions outside the current crop. Use page navigation to inspect the document before you press Crop PDF.
Can I crop only selected PDF pages?
Yes. Choose Selected pages and enter page numbers or ranges such as 1,3,5-8. PdfnMore applies the current crop percentages only to those pages and leaves the other pages unchanged. Every selected page currently shares the same crop percentages.
Does cropping securely remove confidential content?
No. Cropping changes the visible PDF page area and is not a secure redaction method. Do not rely on Crop PDF to permanently remove sensitive text, images or hidden content.
