How to Use the Stamp PDF Online

Stamp PDF: before and after PDF A BEFORE STAMP PDF PDF A AFTER

Stamp PDF lays a stamp PDF over every page of a document. Make a one-page PDF that says DRAFT, CONFIDENTIAL or carries your letterhead, drop both files in, then set how big and how faint the stamp should be. Marking drafts visibly is worth the minute: an unmarked draft circulating as if final is a problem that surfaces late. The stamp is drawn as vector, so it prints clean.

Why Edit PDF Pages Directly?

Going back to the original Word file is not always possible, and sometimes it never existed. Adding text, page numbers, a watermark, a stamp or a header straight onto the PDF finishes the job in minutes.

“The quickest fix is the one made on the file you already have.”
  • No need for the source file
  • Clear ownership with watermarks
  • Margins for binding
  • Crooked or mirrored pages fixed
  • Page numbers on every sheet
  • Headers and footers added
  • Forms you can fill in
  • Correct title and author details

Popular Uses for PDF Editing Tools

Small finishing touches are what most people come to edit a PDF for.

  • Numbering a report Add page numbers to a thesis or report that was saved without them.
  • Marking drafts Put a DRAFT or CONFIDENTIAL watermark across pages before sharing them for review.
  • Legal bundles Apply Bates numbers so every page in a case file has its own reference.
  • Filling a form Type into a PDF application form instead of printing, writing and scanning it.
  • Assignment borders Put the border a teacher asked for around each page of a project.
  • Room for binding Widen the margins so text is not lost in the spine when printed and bound.
  • Trimming white space Crop away wide empty edges so the page reads better on a phone.
  • Approval stamps Stamp APPROVED, PAID or RECEIVED on invoices and letters as they are processed.

What You Can Do with the Stamp PDF

Understands PDF structure rather than treating the file as bytes

Additions are written into the existing page content rather than flattening it to an image

What you place stays sharp at any zoom, because it is drawn as vector rather than pasted as pixels

Best Times to Edit a PDF

Editing the PDF itself makes sense when you are:

  • Missing the original Word file
  • Finishing a thesis for binding
  • Sending a draft for review

  • Filling a form on screen
  • Branding pages before sharing
  • Fixing a page scanned upside down
  • Marking invoices as paid

Tips and Good to Know

  1. The stamp must already be a PDF. Make one from an image with PNG to PDF, or type DRAFT into a blank Word page and save it as PDF.

  2. A stamp drawn over a page can be removed by someone with a PDF editor. For a permanent mark, run Flatten PDF on the result.

  3. For plain text like a page number or a date in the margin, Header and Footer PDF is quicker than building a stamp file.

  4. Every page receives the stamp, positioned in the centre; there is no page selection or corner placement here.

Frequently Asked Questions

Answers to common questions about this tool.

Do I need to install anything to use the Stamp PDF?

No. Stamp PDF runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.

Is it safe to use the Stamp PDF online?

Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.

Can I change words that are already in the PDF?

These tools add to the page: text, numbers, stamps, borders, headers or watermarks. Rewording what is already printed on a PDF is not their job, so for heavy rewriting, edit the original document if you still have it.

Does Stamp PDF leave a watermark of its own?

No. It is completely free, and the site adds no logo or mark of its own. The only marks on your pages are the ones you choose to put there.

Will Stamp PDF work on a scanned PDF?

Yes. Additions such as page numbers, stamps, borders and watermarks are placed on top of each page, so they work on scans just as they do on typed documents.

Can I undo a change after downloading?

The download is a new file, and your original is left exactly as it was. If you want a different result, open the original again and repeat the steps with new settings.
