I had such an experience before. When I was working in a company, the PDF quotation document sent to the client was stolen by my colleagues because there was no watermark. Adding a watermark to an image is a simple matter, but adding a watermark to a PDF document is more complicated. So is there any way to ensure the interests of original works by adding watermarks to PDF, and to ensure that the interests of the original creators are protected from losses? Of course there is!

    First we open the PDF online conversion website - www.pdfasset.com

    Click the "Watermark PDF " icon to enter the document upload page, upload the PDF file that needs to be watermarked, and select the watermark type

    Enter the settings to be adjusted, such as the watermark font size, transparency, etc., and click the "Start Now" button to realize the PDF watermarking operation.

    Click the "Download Now" button to get the PDF watermarked file.
