The PDF, by its nature, is a read-only format. Yeah, you got the Watermark On Pdf that allows you to modify it, etc.; and the Reader allows for some markup, but it was initially designed to be a global standard for read-only documents and/or digital forms that you can fill out. As such, people donât create documents in PDF â t create them in some other app (MS Word, Apple Pages, etc.) and then export them to PDF to be readable on any device. So what you need to do is add the watermark to your document in your designer app, and then export it to PDF together with the watermark. If you donât have access to the source document, only the PDF â then chances are you are not the creator of that PDF, so you donât really have any right to add a watermark to it. The above holds true for Mac, Windows, Linux, etc.
There are many apps out there that include watermarking. Also, check out this video on how to add watermarking in InDesign: If you use a watermark, make sure to leave a little margin around the Watermark, so it doesn't get cut into the page. You can read and edit the watermark once it is in the PDF. As mentioned previously, all the PDFs being made available were made by donors. All the information that went into the creation of a .pdf is not the data used to make the actual PDF. As such, when you open up a .pdf file created by a donor, you can view the details on how the data was used when you open the image or graphic. Here is an example below with one of the best donors to the cause: If you are really interested to see which donor made how many .PDFs please follow this link: And.
