How to Add a Watermark to PDF using Watermarkly
Are you ready to begin? The first thing you need to do is open the PDF watermark adder’s window.
Watermarking your files involves only a few steps:
1. Upload the PDFs you want to be watermarked
Open the folder with the files on your computer and drag them into the app. It is also possible to click on “Select PDF” to upload documents from your device or one of the listed cloud storage options – Google Photo, Google Drive, or Dropbox.
If you choose the latter option, you will need to log into your account and provide access to your files.
Click the “Next Step” button to move on to editing.

2. Design a watermark for PDF
Click on “Add Text” or “Add Logo” depending on the type of the watermark you want to add to your PDF.
Make the most of the app’s available toolkit to design a watermark for PDF:
- drag your watermark to any place you like
- pick a font and color
- change the size
- adjust the level of opacity
- add one of 30 effects to make your watermark eye-catching.

Use the “Tile” option if you want to fill the entire document with repeated watermarks. Arrange them horizontally, vertically or diagonally, rotate them by the desired angle, adjust the space between them, and make them almost transparent so that the text of the file remains readable.
Use the “Duplicate” option, if you want to add more than one watermark in the same style.
Once your watermark on PDF is ready, click Next Step to go to the Export Settings.
3. Preview your watermark on each PDF page
In the editing section, you design your watermark on the first page of your PDF document. But in the “Preview & Adjust” section, you can preview your watermark on every page of the document. If you don’t like the placement, size, color, or transparency of your watermark on some of the PDF pages, make the necessary changes manually.

If you only want certain pages to be watermarked, go to the Page Range settings and select the necessary option.
Once you are done, return to the Export Settings.
4. Watermark PDFs and save the processed files
First, select all the desired options in the Export settings. Take a look at the additional settings:
- Place watermark behind PDF content
- Rename PDF files
Enable them, if needed.

Then, when you’re ready to add a watermark to your PDF documents, click Watermark Files to start processing.
Finally, save your watermarked documents to your device or cloud storage.
Watermark PDF OnlineHow to Design a Watermark That Really Protects Your PDFs
There are a few methods that can make removing your watermark from your PDFs more challenging and time-consuming:
- Fill the entire page of your file with repeated watermarks with the help of the Tile feature. Adjust the size and spacing between them. The contents of the document should still be readable, though, so make your watermarks semi-transparent.
- Make your watermark on PDF large enough to cover the most important part of your document. You might need to adjust the transparency of your watermark here as well.
- Place the watermark behind the text. Once you do this, the watermark will be perceived as an integrated part of the document, and not just a visual element superimposed on top.
FAQ
What is a watermark on PDF documents?
A watermark is a logo, symbol, or text added to a PDF file. It can be opaque or semi-transparent. A watermark shows who the document belongs to or communicates some valuable information – your phone number or website address, for example. Its main purpose is to protect your documents from being copied or distributed without your permission. In some cases, it can also help with promoting your brand.
