How we picked tools to stamp PDF

When making our selection of the best services, we considered several factors:

  • Customization. The PDF editor should allow you to change the text and position of the stamp to fit your specific needs.
  • Quality. The result should maintain its original quality.
  • Security. The tools should have a reputation for reliability and secure handling of sensitive files.

Following these criteria, we've managed to make a list of PDF editing software that offer the best stamping abilities for both personal and professional uses.

How to apply Icecream PDF Editor to stamp PDFs:

What is a PDF stamp

Seals for PDF documents are digital images embedded into the page. 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.

PDF stamp types

TypePurposeExamples
TextContain short phrases or words."Approved", "Confidential", "Draft", "Final Version", "Reviewed", "Urgent"
Image Use graphics, logos.Company logos, Custom pictures (e.g., check marks)
DateAutomatically adds the current date to the document."MM/DD/YYYY"
SignatureRepresent a digital signature or official approval."John Doe" signature, "Approved by [Name]"
ConfidentialityMark the confidentiality level of the document."Confidential", "Internal Use Only", "Top Secret", "Restricted"

Where should I place the stamp?

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

Digital stamps can be applied manually or automatically:

  • Manual require you to drag and drop pictures into a designated stamp box.
  • Automated 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 materials. It also verifies authenticity and protects PDF files.

PDF stamp vs watermark

These are two ways of adding a copyright protection. They both display a footage or words over the PDF but work differently.

  • A PDF stamp is placed directly on the sheet. It can serve as a signature, to certify a document, or simply to incorporate a logo.
  • A watermark is a semi-transparent graphics that appear in the background of a paper. It is often used to protect archives 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 employed 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.Often semi-transparent, covering the entire page or a specific area, providing a background note.
PositioningCan be placed in precise locations, like a corner or center.Usually spans a large area, such as diagonally across or as a background element.
CustomizationHighly configurable in terms of content, size, and position.Adaptable in transparency, position, and angle, but generally serves as a background element.
InteractivityCan include interactive elements such as hyperlinks or PDF form fields.Typically static, though some watermarks might link to external resources.
Use CaseCommonly executed for internal document management and approval processes.Frequently deployed 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.

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 employed to immediately show the status.

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

Reasons to add a stamp to a PDF

  5. Cost-Effective. Creating stamps for PDFs is much more cost-effective than other alternatives such as printing or signing by hand.

Stamps are an easy and efficient way to add professionalism to your drafts while still saving time and money.
