Here is how to use it to stamp PDFs:

  1. Add a file by dragging and dropping or by clicking the "Open…" button. You can upload several PDFs at once.

  3. You will see PDF stamp templates. Hit the one you want to use and choose the place on the page where it will be applied. You can resize the stamp and add a custom description to it.

Stamp on PDF using Adobe Acrobat

Adobe Acrobat allows you to insert a stamp on your PDF and add that personal touch to your documents. Users can upload their images or logos and create stamps with ease.

Plus, it is possible to create custom PDF stamps like animated or password-protected ones. However, you can't add multiple stamps to one page in Adobe Acrobat. Each individual page must have its own stamp.

Keep in mind

  • The main downsides of using this PDF software are its price and complex user interface. The trial version is available for 7 days, to continue using the program you have to purchase a premium subscription. Plus, the interface is unintuitive, especially for first-time users.

Method 3. Google Docs

Google Docs is another tool you can use for editing PDF documents. With its wide array of features, it's also a fine solution for stamping PDFs.

Here's how to do it:

  1. Open your document in Google Docs.
  2. Select "Insert" from the top menu bar.
  3. Click "Image" > "Upload from computer". Import the picture of the future PDF stamp.
  4. Resize and position your stamp as desired, then save your PDF with the newly added image.

Stamping a PDF via Google Docs is an uncomplicated procedure. You can create a PDF seal without any additional software or costs.

Limitations

  • While it's good for creating basic stamps, the service does not offer more advanced features such as stamp customization. Plus, in terms of document security and privacy, Google Docs is not the most reliable platform.

What is a PDF Stamp?

Stamps for PDF documents are digital images embedded into the page. PDF stamping may be used to add a personalized touch to documents or as a way of validating the authenticity of the document. It can contain text, images, logos, and even signature fields.

Where should I place the stamp?

  • Stamps are usually placed in a specific area of the PDF document. This area is usually referred to as the "stamp box". The dimensions of the stamp box depend on the amount of space available in the PDF.

Digital stamps can be applied manually or automatically:

  • Manual stamps require you to drag and drop pictures into a designated stamp box.
  • Automated stamps allow you to upload an image or type in text that will be applied to multiple documents at once.

No matter which option you choose, having a stamp on a PDF adds a professional and individualized flair to your documents. It also verifies document authenticity and protects PDF files.

PDF Stamp vs Watermark

PDF seals and watermarks are two ways of adding a copyright protection to a document. They both display an image or text over the PDF but work differently.

  • A PDF stamp is placed directly on the PDF page. It can serve as a signature, to certify a document, or simply to add a logo to the page. It is possible to personalize PDF stamping with text, images, or even logos.
  • A watermark is a semi-transparent image that appears in the background of a document. It is often used to protect documents from being copied or changed without authorization. Watermarks can be set up on all or just certain pages.

Here's a comparison table to illustrate their differences:

FeaturePDF StampPDF Watermark
PurposeOften used for adding annotations or official marks, like "Confidential", "Approved", or "Draft".Typically used for branding, copyright protection, or to signify the document's status (e.g., "Sample" or "Paid").
VisibilityFully visible and may cover specific sections or pages.Often semi-transparent, covering the entire page or a specific area, providing a background note.
PositioningCan be placed in precise locations on a page, like a corner or center.Usually spans a large area of the page, such as diagonally across or as a background element.
CustomizationHighly customizable in terms of content, size, and position.Customizable in transparency, position, and angle, but generally serves as a background element.
InteractivityCan include interactive elements such as hyperlinks or form fields.Typically static, though some watermarks might link to external resources.
Use CaseCommonly used for internal document management and approval processes.Frequently used for protecting intellectual property and enhancing branding.
ImpactMay alter the appearance of the document significantly, especially if large or prominently placed.Generally less intrusive and maintains the document’s overall layout and design.
LayeringCan be layered over text or images but may impact readability if not managed carefully.Usually placed in a background layer so it does not interfere with the document’s content.
ToolsCreated using PDF editors or specific stamp tools available in PDF software.Created using PDF editors or watermark tools, often included in professional PDF software.

Watermarks are also commonly used on draft copies or copies not intended for the public. In this context, the watermark (for example, "Draft" or "Not for Redistribution") is used to immediately show the document's status.

Overall, PDF stamps are great for quickly adding logos and signatures to documents, while watermarks provide more security as they cannot be easily removed or altered without permission.
