PDF Crop

Crop PDF on iPhone

Crop a scanned PDF page on iPhone by adjusting its boundary, then review the export. Work on each page separately and save a copy before editing if you need the original.

Per-page crop
Best for: scanned book pages with thick margins, screenshots converted to PDF with a status bar visible, slide-deck PDFs with footers or page numbers to remove, receipts with mostly blank trailing space. For irregular shapes or covering up text without resizing the page, use the redaction flow in the PDF editor.

How to crop a scanned PDF page in ScanLens

  1. Save a separate copy before editing if you need the current document.
  2. Open the page adjustment tools and select the page to crop.
  3. Use the detected boundary as a starting point or drag the corners yourself. Keep all required text inside the boundary.
  4. Save the adjustment. Repeat for other pages that need different boundaries.
  5. Export the PDF and reopen it to check margins, small text, and page dimensions.

Crop margins without losing required content

Check dates, signatures, page numbers, and receipt totals near the edge before saving. A crop that suits one page may cut text from another. Cropping is for page framing; it is not a substitute for removing sensitive information with a verified redaction workflow.

Frequently Asked Questions

Can I apply one crop to every page?

ScanLens adjusts the current page. Review and crop each affected page separately; there is no apply-to-all crop.

Does cropping preserve my original in the library?

Page adjustments change the library document. Save a separate copy before editing if you need to retain the original.

Can cropping securely remove personal information?

Do not rely on cropping for redaction. Use a tool that removes sensitive content, then reopen and inspect the exported file.

Why do margins still appear in the attachment?

Reopen the file you attached. You may have shared the original rather than the edited export, or only changed the reading view.

Can I edit a password-protected PDF?

ScanLens cannot import an encrypted PDF or accept its opening password. First open the file in a compatible PDF app using the password you know and save an unprotected copy if you are authorized to do so. Import that copy into ScanLens for the next editing step.
