In this specific case, every page begins with the block q 9 0 0 9 2997 4118.67 cmĪnd nearly 4,000 blocks just like this one. This particular block sets only one ( /W 1 /H 1) of the watermark's pixels. Scrolling down until the pattern changes reveals that the watermark's stream is 95,906 bytes long (counting newlines). The exact same stream is repeated on every page of the PDF file. Press Ctrl + H and set the following: Find: q 9 0 0 9 2997 4118\.67 cm. matches the first line of the above block ( q 9 0 0 9 2997 4118.67 cm) and all following 95,881 characters, i.e., the watermark's stream.Ĭlicking Replace All removes it from all pages of the PDF file. The command pdftk uncompressed.pdf output nowatermark.pdf compress The watermark has now been removed, but the PDF file has errors (the streams' lengths are incorrect) and it's uncompressed. The result is the same PDF without the watermark (and about half the size). The artifacts of the stamp are that you can delete it within Adobe Acrobat Pro, however it regenerates on a mouse-move because the stream object keeps it persistent. If you try to edit the pdf source - which is tricky, there's a chance that the file will be corrupted.

Such fanciness can transform what the reader expects (hopes?) to be a contiguous, easily-searched-for string into a mess of alphabet soup. Having noted all this, I will also noted that PDFtk has a GUI version that purports to handle watermarks, in consideration of a $4 licensing fee. On the other hand, I find its website currently advertises full support for O/S's through Windows 8 and OS X 10.8 Mountain Lion. Might PDFtk be getting outdated?
