How to Add Watermark to PDF in WordPress

In today’s digital era, watermark is no longer a strange term for Internet users. In fact, watermarks are being attached to most of the PDF files and images uploaded online. A lot of WordPress experts prefer having a watermark in PDF files for many different reasons. WordPress, however, doesn’t have a feature for its users to add watermark to PDFs by default. Hence, users need to find a suitable plugin to help them achieve what they want.

This article will provide you with more details about what a watermark is and why it’s important to add one to your PDF files. What’s more, it will introduce you to a supportive Watermark WordPress plugin to help you maximize the watermark’s usage.

Let’s hop to it!

What Is a Watermark?

The watermark’s name might confuse users, but it will make more sense if you dig into the history. It’s believed that back to the 13th century, a watermark was first applied in printing. People at that time made it by changing the thickness in certain places on wet paper to leave a mark. Later on, they came up with a better method. A wet metal stamp or a dandy roll used while producing papers were utilized to create the effect of a grayscale picture.

Nowadays, the watermark is a semitransparent sign which can be a simple text, logo, or pattern that is intentionally superimposed onto the documents. It’s also well-known in the photography and graphic design communities. For copyright protection, they commonly watermark their works of art, i.e. their photos and videos, as well.

Why Should You Add Watermark to Your PDF Files?

The usage of watermarks is pretty practical, but the following two are probably the most common, not to say the main purposes that every online creator is aiming to.

Protect your PDF from file theft

Various artists and authors use watermarks to protect their documents, ebooks, teaching materials, photos, images, and videos. With the open-door characteristic of the online market, there are so many ways that users can access your PDF files without your notice. Additionally, the powerful search engines such as Google and Bing facilitate you to broaden your brand awareness but at the same time, bring several file piracy issues as well.

By adding the watermark to your documents, users who want to steal them cannot have the clean version of your files. In addition to that, the text or image you are using as the watermark comes as a signature to show the document’s original site or author.

Having the watermark in your documents makes it a not-ready-to-print file. File thieves will have to find a tool to remove the watermark, which is a pretty hard and time-consuming process.

In some cases, if you forget to add watermarks to your PDF files, other people can download your original files and add their own. For copyright purposes, you – the author of your documents, should mark your property, claiming the right to your documents so that whoever uses them for commercial purposes will be considered guilty.

Track your work easier

Instead of adding a headline in your PDF document, putting the information like date or address can help you save and organize the document easier with the preview. If you are writing a long ebook or draft a multi-chapter novel, using a watermark to note your work in progress as Draft Copy, Preview, Edited, Chapter 1, etc. will make it simpler to track.

You might use a watermark as a message to your recipients as well. Marking the documents with, for example, Approved or Rejected to the PDF files in a big-size watermark will help emphasize the purpose of the document.
