How do you put a stamp on a PDF from iPhone?

Import the correct PDF, open its annotation tools, choose the available stamp control, and place the visual mark where it communicates the intended document state without covering required text. Review the marked page and export a separate PDF.

A visual stamp is an annotation. It can help a person see a status or instruction, but it does not automatically prove who approved the document, when approval occurred, or whether the file changed later. Use the process required by the recipient.

Step by step: stamp a PDF on iPhone

  1. Import the right PDF. Check the filename, version, page count, and sender before adding a status mark to the document.
  2. Open the annotation tools. Choose the PDF editing or markup area and select Stamps from the supported tools.
  3. Choose an available stamp. Use a visual stamp that accurately matches the workflow. Do not use a stronger status than the responsible person has actually approved.
  4. Place and size the mark. Keep it clear of signatures, totals, form fields, page numbers, and legally significant text.
  5. Review every affected page. Confirm that the stamp appears only where intended and remains readable at normal zoom.
  6. Export a separate stamped copy. Keep the clean source and use a filename that distinguishes the marked version without exposing confidential information.

Stamp, signature, watermark, and highlight solve different jobs

Stamp

A visible status or workflow mark placed on a page. It is not automatically proof of authorization.

Signature

A graphical signature placed where a person is asked to sign. Some workflows require stronger identity or audit evidence.

Watermark

A repeated ownership or status treatment that can appear across one or more pages rather than at one review point.

Highlight

A translucent emphasis mark for text that another person should notice. It is not concealment or redaction.

Where a visual PDF stamp can help

Internal review copy

Mark a working copy so teammates can distinguish it from the clean source while the document is still being reviewed.

Client or vendor handoff

Add the requested visual status when the receiving workflow accepts an annotation rather than a certified approval system.

Page-specific attention

Place the mark near the relevant section instead of applying a document-wide treatment that could imply every page has the same state.

Archived marked copy

Keep the stamped export beside the original so later reviewers can see both the source and the communicated status.

Checks before sharing a stamped PDF

Do not cover content

Inspect the stamp edges at normal zoom and make sure required words, initials, dates, and numbers remain visible.

Confirm the authority

A visual mark should not claim approval, payment, certification, or legal status that the user is not authorized to communicate.

Open the final export

Re-open the PDF outside the editing view and confirm placement, page order, orientation, and visibility.

Keep the clean original

Export a new copy rather than turning the only source into a permanently marked working document.

Frequently asked questions

Can I add a stamp to a PDF on iPhone?

Yes. The current ScanLens annotation tools include a Stamps control for supported visual PDF stamps.

Is a PDF stamp the same as a digital signature?

No. A visual stamp does not automatically provide signer identity, certificate validation, tamper evidence, or an audit trail.

Can I stamp more than one page?

Work through the required pages individually, then review the complete export to confirm that each stamp appears only where intended.

Should I stamp the original PDF?

Keep the clean original and export a separate stamped copy so the mark can be corrected or removed from the workflow later.

Can a stamp hide private information?

A stamp is an annotation, not secure redaction. Use an independently verified redaction workflow for sensitive content.

Add the visual mark, then verify the exported PDF

Use the stamp as a clear workflow cue while keeping the clean source and the final sharing copy distinct.
