How to Add an Approved or Paid Stamp to a PDF Online

If you need to mark a PDF as APPROVED, PAID, DRAFT, or CONFIDENTIAL, the fastest workflow is to add a visible stamp layer on top of the document and export a final copy.

This is useful for:

invoice approval
paid invoice records
draft review copies
internal document control
quick status marking before sharing a PDF

You do not need Acrobat for this workflow. You just need a PDF editor that lets you place a stamp cleanly and export the result.

Quick answer

To add an approved or paid stamp to a PDF online:

Open Edit PDF.
Upload the PDF.
Choose the Stamp tool in the editor.
Select the stamp type you need, such as APPROVED or PAID.
Place and resize the stamp on the correct page.
Export the finished PDF.

If the final file needs to behave more like a static copy, flatten it afterward using How to Flatten a PDF.

When to use a PDF stamp

This workflow is a good fit when you need a visible status mark, not a cryptographic approval system.

Common examples:

marking a vendor invoice as paid
showing that a document version has been approved internally
labeling a review copy as draft
marking a file as confidential before sending it

If you need a handwritten signature instead of a status label, use Sign PDF. If you need a repeating text mark across every page, Add Watermark to PDF may be the better fit.

Step 1: Clean up the PDF before stamping

Before you place any stamp, make sure the document contains only the pages you actually want to share.

Useful prep steps:

remove extra pages with Split PDF
fix sideways pages with Rotate PDF
merge related files first with Merge PDF

This matters because stamp placement is easier when page order and orientation are already final.

Step 2: Open the PDF in Edit PDF

Go to Edit PDF and upload the file.

Dogufy's editor is the right starting point for stamp workflows because it lets you:

add text and annotations
place signatures
insert images
apply visual stamps such as APPROVED, PAID, DRAFT, and CONFIDENTIAL

If your document also needs notes or a signature, it is usually faster to do everything in one editing session before exporting.

Step 3: Choose the right stamp type

Pick the stamp that matches the document's purpose:

APPROVED for accepted or cleared documents
PAID for invoices or payment records
DRAFT for non-final versions
CONFIDENTIAL for restricted internal copies

Use the clearest status possible. If a recipient may misunderstand the stamp, add a short note nearby with the text tool.

Step 4: Place the stamp where it helps, not where it distracts

In most cases, the best stamp position is:

near the top-right or top-center of the page
clear of signatures, totals, and form fields
large enough to scan instantly
not so large that it covers important text

Good placement matters most on:

invoices with totals near the bottom
forms with small printed fields
contracts with initials or signature blocks

If you are stamping a multi-page file, check each page carefully before exporting. A stamp that looks fine on one page can overlap content on another if page sizes differ.

Step 5: Export the PDF and review it once

After placing the stamp:

export the PDF
open the downloaded file
check that the stamp is readable at normal zoom
confirm it does not block names, dates, amounts, or signatures

This quick review catches most mistakes immediately.

If the file becomes too large after editing, run it through Compress PDF before sending it.

When to flatten the stamped PDF

Some teams want the final stamped copy to behave more like a fixed record.

Flattening can help when:

the recipient should not keep editing the visible stamp
the upload portal behaves better with a simpler final PDF
you want a cleaner "final copy" after annotations are finished

For that workflow, use How to Flatten a PDF (Make It Non-Editable).

Important: flattening is about document behavior, not security. A flattened PDF can still be copied, shared, screenshotted, or processed with OCR.

Best workflow by document type

Invoice marked as paid

Use this order:

remove extra pages with Split PDF if needed
open Edit PDF
add the PAID stamp
export and review totals and dates
compress if the file is too large

Internal draft for review

Use this order:

merge pages if the draft is spread across files with Merge PDF
open Edit PDF
add the DRAFT stamp
add comments or text notes if needed
export a shareable copy

Approved final form or agreement

Use this order:

confirm all pages are upright with Rotate PDF
add the APPROVED stamp in Edit PDF
add a signature with Sign PDF if required
flatten the final version if your workflow needs a more static copy

Common problems

The stamp covers important text

Move it closer to a corner or reduce the size slightly. The stamp should be obvious, but it should not block fields, totals, or signature lines.

I only need a signature, not a stamp

Use Sign PDF. A status stamp and a signature solve different problems.

I need the same mark on many pages

If you need a repeated background-style label rather than a single status mark, Add Watermark to PDF may be more efficient.

The file is too big to email after editing

Run the exported result through Compress PDF. If the PDF came from scans, compression usually helps more than it does on simple text PDFs.

FAQ

Is a PDF stamp the same as a digital signature?

No. A visible stamp is a status marker. It is useful for workflow communication, but it is not the same thing as a cryptographic digital signature.

Can I stamp an invoice as paid without changing the rest of the PDF?

Yes. The practical goal is to place a visible PAID mark and export a clean final copy while leaving the original content readable.

Should I use a stamp or a watermark?

Use a stamp when you want a clear status mark in one area of the page. Use a watermark when you want a repeated or page-wide label such as draft or confidential.

Can I add a stamp and a signature in the same workflow?

Yes. Open the file in Edit PDF, place the stamp, add any text or other edits, then sign it if needed before exporting.
