Topic in Brief:
Watermark PDF

We all tend to create PDF files often and that is for a good reason. They are very easy to read, showcase professionalism and they are a lot harder to modify when compared to regular documents. Plus, using PDF files allows you to add in more media and value to the entire experience which is an extraordinary thing in its own right.

When do you need a watermark on the PDF though? There are quite a lot of situations to be honest. You might find situations when you want to add sensitive or proprietary information. The same thing can happen when you have something you created and you just don’t want to share it with others there are situations that do appear very often and you have to do all you can in order to avoid them. Adding in a watermark will allow you to eliminate the hassle and instead it will offer a great, refined experience! You can find 3 different solutions when it comes to watermarking PDF, all you have to do is to give them a try and see which one suits your needs.

Adobe Acrobat is a popular solution when it comes to viewing and adding PDF. However, the interface is very complex and convoluted which might make it hard for a regular user to find the best way of adding in a watermark to that PDF. With that in mind, there are still solutions to be had for this type of problem. The way you add a watermark to an open document is actually quite complicated.

Step 1. You will be able to reuse the watermark if you can. Using a text watermark requires you to press the TEXT option then you can add text in the box, but if you want an image then you have to click File/Browse and then select the image you want.

Step 2. They allow only PDF, JPEG and BMP images as watermarks so you are limited to a small amount of formats.

Step 3. Changing the image watermark size will require you to either choose the Absolute Scale option that will help scale it or you can scale according to the target page. You will have to manually adjust the position and appearance of the watermark, so it might take a little bit of time to do that the proper way.

Step 4. There are also some appearance options that allow you to decide if the watermark will appear when printing or other similar situations.

As you can see, Adobe Acrobat doesn’t really manage to make the PDF watermarking process easy. With that in mind, here are its pros and cons.


You have many options to choose from, you can decide if the watermark will appear when you print the PDF, you can add both text and image watermarks.


The interface is very complex and not that intuitive. New users will get lost in the numerous options and many of them are not explained properly which makes using this app a chore at times.

Very Easy



This site is a good option if you want to watermark PDF in a simple manner. It’s very easy to use but it does lack many of the features that you would expect from a fully fledged PDF editing tool or watermarking tool.

Using it is easy, you just need to:

  • Step 1. Visit the site and select the desired pdf
  • Step 2. Write text or use an image
  • Step 3. You can change the positon, transparency and typography

The simplicity of this tool makes it great for beginners and people without a large need of PDF features, but if you want high class and high quality PDF work you will be a little disappointed here unfortunately.


Simple and intuitive. You can use both image and text as watermark. You can change the positioning.


It’s way too simple and it lacks some transparency and better positioning since you are limited to just 3 places.
