Add encryption to existing PDF?
Posted: Mon Aug 22, 2011 10:45 pm
Sometimes I receive PDF documents that all I need to do is create a copy that is encrypted.
But NovaPDF does not like to 'print' from an existing PDF file.
Therefore I have had to resort to using an "image printer driver" to print the original to a graphical image, and then print that via NovaPDF, adding encryption. But the resulting PDF files are huge. (presumably since they are now graphical data, rather than textual)
Is there any solution for this, or does it mean I have to buy expensive Adobe software?
