Add professional stamps to your PDF documents in three simple steps — no software needed.
Drag and drop your PDF file into the upload area, or click "Choose PDF File" to browse your device. The tool accepts any standard PDF document. Once uploaded, all pages are rendered so you can navigate to the page where you want to place your stamp.
Select a preset stamp such as Approved, Confidential, Draft, Rejected, Final, or Urgent — or type your own custom text. Choose the stamp color, size, and rotation angle. Then click on the page to place the stamp exactly where you want it.
Once you have placed all your stamps, click the download button to save the stamped PDF. The stamps are permanently embedded into the document. Your original file is never modified — a new copy is created with the stamps applied.
The fastest way to add professional stamps to PDF documents — free, private, and easy to use.
No premium tier, no usage limits, and no hidden fees. Stamp as many PDFs as you need without creating an account or paying a subscription fee.
Your files never leave your device. All stamp processing happens locally in your browser using JavaScript. There is no server upload, no cloud storage, and no data collection.
Choose from professional preset stamps like Approved, Confidential, Draft, Rejected, Final, and Urgent. Or create your own custom text stamp with any wording you need.
Control the color, size, rotation angle, and opacity of each stamp. Create bold red "CONFIDENTIAL" stamps or subtle grey "DRAFT" marks — the choice is yours.
Add stamps to any page in your document. Navigate through pages and place different stamps on different pages, or apply the same stamp across multiple pages for consistent marking.
ConvertKr never adds its own watermarks or branding to your stamped PDF. Only your chosen stamps appear on the document. The result is clean and professional.
