PDF files are more important than any other types of files, and they are used widely in computers and mobile phones. The idea is that PDF files have some features that are not in any other files, such as the ability of containing large amounts of data at a small size. Also it is easy to exchange these files on different devices. In this article we will explain the way of adding a watermark to a PDF file online without using any software, Where we will depend on using some online tools that do this function perfectly.
How to Add a Watermark to a PDF:

This tool I prefer because it gives me the result I need in simple steps. Also it provides you with morecontrol options for adding watermarks to the PDF file as we will indicate. First, go to “iLovePDF Add watermark into a PDF” and then click on the red button “Select PDF file” to add the PDF file that you want to add a watermark on it. After that the PDF file will appear on the left side of the website as you see in the next image.
On the right side you see two options under “Watermark options”. The first option is to add the watermark as a text, and the second option is to add it as an image. Suppose we will add a text, So we will write in the space provided for writing. Under “Text format” you can edit the text by enlarging or reducing it, and you can select a different font from the list and you can also change the color you use.
Then under “Position” you can control the position of the watermark, and you can mark the option of “Mosaic” to make the watermark appear in all places of the PDF pages. You can scroll below to edit “Transparency” of the watermark and you can rotate it by 45 degrees or more. Note, You can choose some pages to place the watermark on it. Finally, Press on the “Add watermark” button to put the watermark with the settings you made.
Then you will be redirected to another page and the PDF file will be downloaded to your device directly, and from this page you can share the download link to the final PDF File, and also you can save it in Google Drive or Dropbox.
Note, you can repeat the above steps but with inserting a watermark as an image. To do that you will click on the “Place image” tab instead of “Place text” tab. Then you choose the watermark you want to add.
