Freeware PDF unlocker

#1 Post by Numanoid » Fri May 30, 2008 12:37 pm

I found this programme to be of great help to liberate PDF documents

http://www.freewarefiles.com/Freeware-P ... 27137.html

I am running it from my USB key, so I think it very well might be a portable application.

I'm not sure how useful this is!
I stand to be corrected but I think you have to know the password.

According to the read me file that came with this programme:

There are two types of passwords that can be used in a PDF file
1. A password that restricts some functions, such as printing. This is the most common type. {Owner}
2. A password to open the file for reading. {User}"

This programme can remove passwords of type 1, but to remove type 2 requires that you know the password to open it.

I had a couple of manuscripts (200+ pages) that I wanted to add bookmarks in, this programme unlocked them in a couple of seconds. So I can certify that it works well removing type 1 passwords at least :)

if this will let you print after removing passwords of type 1

then couldnt you print it to pdf

and then read it ????

maybe this isnt a portable option but a large number of freeware pdf printers are out there

for now some solutions are not portable

but hopefully this would defeat type 2 passwords

I bet their is a better solution already in the database though

Hello folks,

How did you make it work from the pendrive? I tried a lot, but I am not good with windows cmd commands. Can someone help here?

See you later,

Freeware PDF Unlocker - Creating a Launcher

#6 Post by Aeolis » Sat May 15, 2010 12:08 pm

Hello folks,

I am trying to make Freeware PDF Unlocker running from a USB sticky. Until now I was able to extract all the necessary files to a folder named Freeware PDF UnlockerPortable. I have figured out that the file that unlock pdf's is the unlockpdf.cmd and it's a Windows command line file with the following commands:

@echo off
echo.
echo.
echo This may take a minute, please wait.
echo.
echo.
echo.
echo.
set ttt=%1
set tt=%ttt:~0,-5%
gswin32c -dSAFER -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sFONTPATH=%windir%/fonts;xfonts;. -sPDFPassword= -dPDFSETTINGS=/prepress -dPassThroughJPEGImages=true -sOutputFile=%tt%_noPW.pdf" %1

I would like to know if there is a way to make the cmd file open and unlock a pdf when I drop the file over it? I am not good with Windows command line arguments. Could somebody help me here?

See you later,

Aeolis

Very old thread update:

The original link is offline so I went digging. He might have been referring to this: https://sourceforge.net/projects/portablepdfunlocker/ … it's open source and appears to have been updated back in 2014 (and a x64 version added 6 months later). Hopefully it's that and not the other same-named commercial program.
