Crop PDF questions
Is my PDF uploaded?
No. Previewing and cropping run locally in this browser.
Does cropping reduce PDF quality?
No. The tool changes each page's visible boundaries without converting pages into images.
Can I preview the crop before downloading?
Yes. Drag and resize the crop box on the large page preview to see the retained area before processing.
Can different pages use different crop areas?
Yes. Apply one crop to all pages or choose Current page only and set each page separately.
Can I enter exact crop margins?
Yes. Enter top, right, bottom, and left percentages alongside the visual crop box.

About this tool
Adjust the visible area of every PDF page
Crop PDF applies percentage-based crop boundaries to hide unwanted outer areas. A preview helps you choose balanced margins before saving.
Useful for
- Remove scanner borders or excess white space.
- Create consistent visible margins across all pages.
- Focus a document on its central content area.
Good to know
- The same crop percentages are applied to every page.
- Cropping changes page boxes and may not securely delete hidden content.
- Use Redact PDF—not cropping—when sensitive information must be removed.
Practical guidance
Crop PDF page margins and unwanted outer areas
Crop PDF changes the visible page area to remove scanner borders, excess white space, or unwanted content near the edges. Choose percentage-based crop boundaries, inspect the preview, and apply the same crop settings across the document.
Crop PDF pages online with a preview
Adjust top, right, bottom, and left boundaries while checking that headings, page numbers, signatures, and other important content remain visible.
Apply consistent crop margins
The same crop percentages are used on every page. This works best when the source pages share a similar size and layout.
Do not use cropping as secure redaction
Cropping changes the visible page boxes and may not securely remove hidden content. Use Redact PDF for sensitive selectable text and verify the sharing copy.

Can I use a different crop for each page?
No. The current tool applies the same percentage boundaries to every page in the selected PDF.
Will cropping permanently remove sensitive information?
Do not rely on cropping for redaction. Hidden or recoverable content can remain; use an appropriate redaction workflow instead.

PDF cropping versus redaction: which should you use?
Use cropping for layout and visible boundaries, but use a verified redaction workflow for sensitive information because hidden cropped content may remain recoverable.
