How to stamp PDF

It takes less than a minute with PDFHeron.

  1. Open the PDF

    Drop the document onto this page.

  2. Pick a stamp

    Choose from 12 ready-made stamps or type your own text, and pick a color.

  3. Options

    Add today’s date under the text, or tilt the stamp for a classic rubber-stamp look.

  4. Place and save

    Drag the stamp into position, resize it, then download your PDF.

Ready-made and custom stamps

Approved, Rejected, Draft, Confidential, Final, Paid, Received, Void, Copy, Urgent, Reviewed and Not Approved are one click away, each in a sensible color. Or type any text, such as your company name or “Checked by QA”.

Check marks and dates for forms

The same panel places check marks, crosses and dots, plus today’s date as text, which makes it quick to complete paper-style forms.

Why use PDFHeron to stamp PDF?

Private by design

PDFHeron processes files on your device. No uploads, no cloud copies, no one else ever sees your documents.

Real editing

Change existing text and delete content from the file itself, not just paint boxes on top of it.

Instant & offline-ready

No queues or upload waits. Big documents open in seconds, and editing keeps working without a connection.

True redaction

Redacted areas are permanently removed from saved PDFs, so hidden text can’t be copied back out.

Standard PDF output

Saved files are regular PDFs with selectable text that open in Acrobat, Preview, Chrome and every other reader.

Free, or $2 once

Use every tool for free. Remove the footer forever with a one-time Pro license, with no subscription.
