Understanding PDF Stamping
What is a PDF Stamp?
A pdf stamp is a text or graphic overlay applied on top of PDF page content to communicate the document's status, classification, or intent. Common pdf stamps include APPROVED, CONFIDENTIAL, DRAFT, and COPY — each carrying a widely recognised meaning in business and legal workflows. Unlike a watermark which is often a background image, a pdf stamp is typically a bold, prominent text label positioned prominently on the page. Our pdf stamp tool lets you apply any of these presets or create a fully custom stamp with your own text, color, and style in seconds.
How Our PDF Stamp Tool Works
- Upload your PDF — Drop your document into the upload zone. The pdf stamp tool loads it entirely in your browser using the pdf-lib library for accurate page dimension detection and text rendering.
- Configure your stamp — Choose a preset (APPROVED, CONFIDENTIAL, DRAFT, COPY) or enter custom text. Then set the color, opacity, font size, rotation angle, position, and whether to apply the stamp to all pages or a specific page.
- Download your stamped PDF — Click "Download Stamped PDF" to render the pdf stamp onto your pages and trigger an instant browser download. The output is a standard PDF compatible with all major viewers.
PDF Stamp Styling Options
- Color— Choose Red, Green, Blue, or Gray to match your organization's document standards. CONFIDENTIAL is conventionally red; APPROVED is green.
- Opacity — Set transparency from 10% to 100%. A 30–50% opacity creates the classic semi-transparent pdf stamp appearance that lets underlying text remain legible.
- Rotation — Rotate the pdf stamp from -90° to +90°. The standard diagonal stamp uses -45° for a professional, official document look.
- Border — Optionally add a matching colored rectangle border around the stamp text for a formal boxed-stamp style used in legal and procurement workflows.
Privacy, Security & Availability

Your PDF file is never transmitted to any server, never stored in the cloud, and never accessible to any third party. This makes the pdf stamp tool safe for confidential documents including legal agreements, financial statements, medical records, and sensitive business materials. The tool is free to use with no account, no subscription, and no file size restrictions — available on any device with a modern web browser.
