Did you know?

What is a watermark?

A watermark is a logo or text that is inserted over any type of document or image file, including PDF files. The most common form of watermark is the embedding of an image or text in a document, and is one of the most effective ways to protect PDF files and documents containing confidential or proprietary information. If a document is shared without permission or if a copyright dispute arises, the person who owns the content must be able to prove that the content belongs to them. In this case, you can prove that you are the owner by embedding a watermark on the document. Watermarking documents is useful for both individuals and businesses.

When are watermarks used?

Copyright protection

A watermark protects the copyright of a document and prevents the material from being used elsewhere or altered without permission. That is, the document or image is protected by the author, so the intention is to prevent others from using the content without permission.

Proof of document validity

Watermarks can be used to protect confidential information and to indicate the validity of legal documents. For example, anyone who has conducted digital contracts online or handled legal documents will have seen watermarks applied to those documents.

Brand awareness

It can be used as a way to increase brand awareness for individuals or companies. For example, some brands add a visual logo or name to every file they send to their customers. People will be much more likely to remember your logo or name if they see it often. This helps increase brand awareness.

Sharing information

A watermark can be inserted in the form of text into a document. For example, you can include text with phone numbers, emails, and website addresses in documents that you distribute publicly so people know how to contact you.

Document classification

Including words like “confidential,” “original,” or “copy” in your PDF helps show and track people what type of file they received.

If I add a watermark to a PDF document, does it change the content?

No, watermark insertion only adds watermarks in image or text form to the original PDF and does not change anything, including layout and other file types.

Can I add a watermark to documents in formats other than PDF?

I entered text for watermarking in the PDF, but the text appears garbled in the applied PDF document.

If the characters entered for watermarking are Unicode-based characters, be sure to select the Arial font. Currently our PDF solution does not support Unicode based characters other than the Arial font when watermarking. However, it is under development to support various fonts.
