8 Free PDF Password Remover Tools

A PDF password remover (also called a PDF password cracker, password reset, or password recovery tool, depending on its ability) is a program that can be used to either find, remove, or bypass the security on a PDF file that prevents you from opening, printing, or changing the PDF file.
Most PDF password cracker tools fall in to one or more of three major categories: tools that recover the PDF user password, tools that recover the PDF owner password, and tools that remove the PDF owner password allowing full access to the PDF file.
The majority of PDF password remover tools cost money but there are also plenty of free PDF password removal, recovery, and cracking programs and the best of them are listed below:
Note: An individual PDF password removal tool might only support the cracking or removing of a password if it's of a certain kind, for a certain security level, encrypting a certain version of PDF, or may even have other restrictions. I'll call out any of those known limits below.
Important: In most countries, the only legal use of PDF password crackers is to break the security on a PDF file that you have the permission to do so on, like a PDF you encrypted but forgot the password to.

1. PDFCrack

PDFCrack is the best free PDF password recovery tool available, assuming that's what you're after - an actual password "recovery" and not a simple PDF password removal or reset.
Method: PDFCrack would be considered a true PDF password recovery program since it recovers both the user password and owner password from encrypted PDFs. PDFCrack uses a brute-force password recovery method.
Limits: PDFCrack works with PDF files up to version 1.6 with 128-bit RC4 encryption.
My Test: PDFCrack recovered the 4-digit owner password on a version 1.6 PDF file with 128-bit RC4 encryption in two minutes. A longer and/or more complicated PDF password could take days, weeks, or even longer to recover.
If all you need is a way to bypass the permissions security in a PDF then PDFCrack is probably more than you need in a PDF password cracker. However, if you need to know the actual owner or user password, PDFCrack is your best bet.
PDFCrack is a command-line tool and should work on Windows 7, Windows Vista, and Windows XP, including both 32-bit and 64-bit versions.

2. GuaPDF Demo

GuaPDF, sometimes referred to as Guaranteed PDF Decrypter, is a combination PDF password remover/recovery tool. GuaPDF is easy to use and doesn't even require installation.
Method: GuaPDF is primarily a PDF password remover tool for the owner password but can also be used as a PDF password recovery tool for 40-bit encrypted user passwords.
Limits: GuaPDF works with PDF files up to version 1.7 level 3 even with 256-bit AES encryption. However, GuaPDF will only decrypt PDF files at higher levels of version 1.7 if the encryption is at 128-bit AES.
My Test: GuaPDF removed the security on a version 1.7 level 8 PDF file with 128-bit AES encryption instantly.
I recommend that you pick GuaPDF as your PDF password cracker if you have a small PDF with only owner restrictions, which is probably the most common situation. If you need to recover the owner password, try PDFCrack instead.
GuaPDF works on 32-bit and 64-bit versions of Windows 7, Vista, XP, 2000, and most Windows server operating systems as well.
Important: Including "demo" software in a list of freeware programs might seem wrong but the GuaPDF demo is fully functional for small files - it doesn't watermark or pretend to remove the password. Considering that it works across almost all PDF versions and encryption levels, something not found in most other true freeware PDF password removers, I couldn't skip on including GuaPDF here.

3. Freeware PDF Unlocker

Freeware PDF Unlocker does just that - it "unlocks" an encrypted PDF file. Freeware PDF Unlocker is unique in that you just drag a PDF file to the shortcut the program creates on your desktop during installation and a few seconds later, a renamed and password-free PDF file is created on your desktop.
Method: Freeware PDF Unlocker is considered a PDF password remover or cracker tool. It doesn't find the actual PDF password, it just removes it and the associated security allowing full access to the PDF.
Limits: Freeware PDF Unlocker works with PDF files up to version 1.6 but reduces the new password-free file to PDF version 1.5. Freeware PDF Unlocker will not remove the user password unless you already know it.
My Test: Freeware PDF Unlocker removed the security on a version 1.6 PDF file with 128-bit RC4 encryption almost instantly.
If you just want to get past the permission security in the PDF but don't need to know the actual owner password used to secure the file, Freeware PDF Unlocker is a great choice.
Freeware PDF Unlocker should work on 32-bit and 64-bit versions of Windows 7, Windows Vista, Windows XP, and Windows 2000.
Note: The screenshot to the left is the Command Prompt window that opens up and performs the PDF rewriting process but there's no command-line work needed to make this work, it's just the drag-and-drop I mentioned above.

Method: PDF Password Remover Online is considered a password remover or cracker tool since no passwords are actually discovered.
Limits: PDF Password Remover Online works with PDF files up to version 1.7 level 8 with 128-bit AES encryption. The maximum PDF file size is 10 MB.

Since there's nothing to install with PDF Password Remover Online, and there's no options to confuse or complicate the PDF cracking process, this is one of the easiest to use tools available.
Since PDF Password Remover Online is a browser based application, it will work with any operating system you happen to be using.
Note: If you like PDF Password Remover Online but don't like the thought of uploading your PDF file, try PdfCrypt, also listed here. PdfCrypt is the desktop version of PDF Password Remover Online. If the file size limit is the concern, try FreeMyPDF.com instead.

6. PDF Password Remover

PDF Password Remover (no relation to PDF Password Remover Online as far as I can tell) is another installable PDF password remover. It has a very simple PDF-in / PDF-out interface.
Method: PDF Password Remover's name says it all - it's a PDF password remover tool for the PDF owner password and that's all it does.
Limits: PDF Password Remover works with PDF files up to version 1.7 level 8 with 128-bit RC4 encryption.
My Test: PDF Password Remover instantly cracked a version 1.7 level 8 PDF encrypted at 128-bit RC4.
PDF Password Remover is really easy to use but doesn't support some of the higher encryption levels. This might be the perfect PDF password cracker/remover tool for some PDF files but you'll want to make another choice if the encryption level demands it.
I tried PDF Password Remover on a 64-bit Windows 7 PC but it should work equally well in Windows Vista and Windows XP.

7. PdfCrypt

PdfCrypt is the Windows command-line version of PDF Password Remover Online. Just specify the input and output PDF and a decrypted PDF file is instantly generated.
Method: PdfCrypt is a password remover tool. PdfCrypt will not find an owner or user password.
Limits: PdfCrypt works with PDF files up to version 1.7 level 8 with 128-bit AES encryption.
My Test: PdfCrypt decrypted a small version 1.7 level 8 PDF file with 128-bit AES encryption in less than a second.
I think PDF Password Remover Online is a better choice over PdfCrypt for PDF files smaller than 10 MB because the web interface is so easy to use. However, PdfCrypt is the perfect alternative to PDF Password Remover Online for larger PDF files.
PdfCrypt should work equally well in 32-bit and 64-bit versions of Windows 7, Windows Vista, Windows XP.

8. PDF Unlocker

PDF Unlocker is a Windows installable program that will find the owner password of a PDF file. PDF Unlocker works much like PDFCrack but is instead a native Windows application, making it a bit easier to use though noticeably slower.
Method: PDF Unlocker sounds like it might be a PDF password remover tool but in reality it's a PDF password recovery program since it discovers the actual owner password from an encrypted PDF. PDF Unlocker uses a brute-force password recovery method.
Limits: PDF Unlocker works with PDF files up to version 1.7 level 8 with 128-bit AES encryption.
My Test: PDF Unlocker recovered the 5-digit owner password on a version 1.7 level 8 PDF with 128-bit AES encryption in about an hour and that's with me specifying the minimum and maximum password length, something you might not know. A longer password or a password where you don't know the length beforehand could take PDF Unlocker several days, weeks, or longer to crack.
If you need to know the actual owner password of an encrypted PDF file then PDF Unlocker is a good bet, especially if the PDF is encrypted at a level that the much faster PDFCrack can't handle. If you don't need to know the PDF owner password, but instead just want it removed, try one of the PDF password remover programs.
PDF Unlocker should work in Windows 7, Windows Vista, and Windows XP, including both 32-bit and 64-bit versions.
Note: PDF Unlocker requires that Java is installed before you can use the program. The program also tries to get you to install a browser toolbar during installation but you can cancel it and PDF Unlocker's install will continue fine.

How to lock any file or folder without any software

Most of us have private data. Not all of us have a private computer to keep that data. So, we just end up with other people viewing that data. Although password protecting software do work, it is almost useless to hide private data with these software(because we are always questioned as to what it is that we are hiding with the help of these software).

Hidden folders do not work as they can be easily searched with Windows Search. So, we need an alternative way to create hidden password protected folders which only we can access. And that is exactly what we will learn in this post.

With this trick, you can create a secure password protected folder in Windows which no one except you can access. To use this trick, follow the instructions given below:-

• 1.  Open Notepad.

• 2.  Copy and paste the exact code given below:-

cls
@ECHO OFF
title computer-tricks-corner.blogspot.com
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST MyFolder goto MDMyFolder
:CONFIRM
echo Are you sure to lock this folder? (Y/N)
set/p "cho=>"
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM
:LOCK
ren MyFolder "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
echo Folder locked
goto End
:UNLOCK
echo Enter password to Unlock Your Secure Folder
set/p "pass=>"
if NOT %pass%== computer-tricks-corner.blogspot.com goto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" MyFolder
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDMyFolder
md MyFolder
echo MyFolder created successfully
goto End
:End

• 3.  Click on the File Menu. Click on Save As.

• 4.  Select All Types (or all files) in the Save As Type dropdown menu. Save the file as *.bat or Locker.bat 

 
After creating the file, double click on the Saved file. A new folder will be created. Enter your data in the folder. Again, double click on the batch file. Type Y and press Enter. The folder will be hidden from view.

To re-view your folder, double click on the saved batch file. Enter password as
" computer-tricks-corner.blogspot.com " without quotes ("") and press Enter key. This is also the default password. Your folder will be visible again.

To change the default password, edit the part of the code given in blue and enter your own password.

The overall usability of this trick can be improved by deleting the batch file after hiding your folder and re-creating it when you wish to access your folder again.

If you face any problem using this trick, you can write a comment and I will do my best to help you.

Note : This works on Windows 7, Windows XP and Vista. First try this on useless data to be sure and then only hide your personal data.
