How to Add a Stamp to a PDF Online and Insert Digital Marks
Place official visual stamps onto your active document pages effortlessly. Instead of printing documents just to apply a physical ink validation mark and scanning them back, our interactive workspace allows you to insert digital stamps into PDF files natively.
Whether you need to apply a company approval stamp to an invoice, overlay dynamic real-time date marks onto audit logs, or place specific corporate operational flags like Approved, Rejected, Confidential, or Void across legal agreements, this tool streamlines your document workflow.

Key Features
When you choose a template or upload a graphic in the Stamp workspace, the rendering engine initializes three foundational placement layers:
1. Dynamic Text Placeholders
Manual datestamping is prone to human error. Our system features smart macro fields that automatically generate real-time signature dates, current times, and custom user identifiers. Every time you place the stamp, the system recalculates these values dynamically to ensure pristine records.
2. Custom Image Stamping Library
Maintain your corporate branding across all official communications. The canvas supports transparent PNG graphics, vector logos, and digitized legal seals. You can import custom graphic layouts directly into a ready-to-use template library for fast, recurring deployment.
3. Accurate Coordinate Mapping
Placing markers precisely on complex documents shouldn't be difficult. Our responsive canvas lets you lock stamps onto exact coordinate areas using your mouse or apply them uniformly across a sequential range of pages—such as stamping every page of a contract as Confidential simultaneously.

Frequently Asked Questions
Can someone remove or edit a stamp after I save the document?
By default, standard stamps sit as interactive annotations. However, when you download your final document from our tool, you can select the Flatten option. This burns the stamp vectors directly into the core page layout, merging it with the background text so it cannot be selected, moved, or deleted by receivers.
Does the tool support transparent logos for stamping?
Yes. Our engine fully reads alpha channels inside images. If you upload a transparent corporate logo or an isolated handwritten signature stamp in .png or .svg format, it will overlay onto the text without any ugly square white background boxes.
