How to watermark a PDF



Have you ever wondered how to watermark a PDF document? A watermark is a semi-transparent image that is embedded into the pages of your PDF. They are currently used to authenticate your document in an official capacity.

Historically, watermarks have been used to prevent counterfeiting since this specially designed image will appear in the same location on each page. Before the digital era, watermarks were applied to paper as the pages were being created. This took place while the paper was still wet and while the paper could easily be marked by altering its thickness.

A watermark is an excellent way to brand your documentation. You can use any graphic you’d like and this creates a wide berth of customization. Effective use of a watermark will instantly make any PDF appear more professional while also increasing document security.

Watermarks have found their place in the digital era. Instead of needing to print to specially marked paper, you can apply the watermark directly to a PDF document. The best part of digital watermarks is you can easily remove them and start over if you need to make any corrections.

While using an application like Soda PDF, applying a watermark to your PDF is a few clicks away. This article will explain how to watermark a PDF, and then remove it.
