Cropping a PDF changes the area a viewer and printer treat as the visible page. It is useful for removing scanner borders, excessive white margins, registration marks or an unwanted edge captured beside a document. This tool expresses the crop as percentages from the top, right, bottom and left, with a preview of the first page showing exactly which region will remain visible. The same crop can be applied to every page or limited to an explicit page range, and the operation runs directly on the PDF page boxes rather than photographing the pages again.
What happens to the PDF
- Choose a PDF. Page one is rendered locally at preview resolution and the total page count is read without sending the document anywhere.
- Adjust each margin percentage. The shaded preview represents content that will sit outside the new crop box, while the outlined centre remains visible.
- Leave the page field empty to crop the complete document, or enter ranges such as 1-3,5 when only selected pages share the unwanted border.
- Download the rewritten PDF and inspect representative pages before replacing or distributing the original.

Trim only an appendix
Enter the appendix page range and apply margins that match those scanned sheets without altering the main report.
Check before relying on the PDF
- Cropping hides material outside the crop box; it does not securely erase that content. Use a genuine redaction workflow for confidential information.
- One percentage crop may not suit pages with different scans or orientations. Apply separate runs when sections need different margins.
- The first-page preview is a guide. Always inspect later pages in the downloaded result when the source document is inconsistent.
- Digital signatures are invalidated by any page-box modification. Preserve the signed original.
- The tool limits each side to 45 percent so an accidental setting cannot collapse the page to nothing.
Questions about Crop PDF
Will text remain selectable after cropping?
Yes. The page crop box changes, but the original PDF content is not rasterized into a picture.
Is cropping the same as redacting?
No. Hidden content can remain in the file outside the visible crop area. Never use this tool to remove sensitive information.
Can I crop only one page?
Yes. Enter that page number in the page field before running the crop.
