This video tutorial teaches how to add a watermark to a PDF file by using a PDF writer object to create a new PDF file and a PDF reader to read an existing file. A loop is used to iterate through each page, with the content being added to the PDF writer. The final step involves writing the data to an output PDF file, effectively copying each page from the existing file. The watermark PDF file is read and the watermark page is retrieved and merged into the content of the input file.
