Posted a previous question about removing the password from a PDF that I DO have the password for. Just to simplify opening it going forward (accountant emailed tax returns with our SSN on them). Different ways to do that, but printing to a new PDF is 1 way and seems to be (for me) the cheapest / simplest way.
Touches on another issue that I've wondered about for a long time.
Printing a PDF (or even a web page or text doc, etc) to PDF using different apps can yield wildly different size documents.
Any (free preferred) app that you like for printing to PDF ... and makes small resulting files?
I know with this password protected file (monochrome text), the original was 90KB and any app I tried using to make a PDF resulted in files that was hundred Kilobytes / megabytes.
And even PDF Forge - for a password protected PDF, it won't even print to PDF (at least when viewing it from Adobe Reader.
From PDF Forge forum:
it isn't really up to us, this is a Ghostscript "feature". Ghostscript is what PDFCreator uses internally to convert the Postscript print data to PDF and other formats.
The idea behind it (I guess) is that you can't use Ghostscript to strip protection from PDF files. Even though the settings allow print, printing it to a virtual PDF printer will basically remove the user password for you, so it is really something different than printing it to a piece of paper. On the other hand, if you have the password and you can view/copy all content anyway, you might as well directly be able to create an unprotected PDF from the password protected file.
You can actually print it to PDFCreator, you just can't use PDF as output format (if printed from Adobe Reader).
The best solution (in my opinion) is to simply print the PDF with PDF Architect or SumatraPDF instead of Adobe Reader.
That brings up another question - Does the size of the resulting PDF depend on the combination of PDF viewer AND PDF Printer app? Ie using pdf viewer A vs. pdf viewer B give a different resulting PDF file when printed with the same PDF printer app?!
