PDF Unlock Utility
A while back I purchased an ebook in PDF format. When I tried to open it under my Linux laptop I got an unpleasant surprise, the ebook's author had used a font that wasn't available on my Linux box, therefore the ebook was unreadable.
I figured I can simply copy the text and paste it into a text editor or word processor, but to my dismay I found out it wasn't possible to copy text from the PDF.
I had heard about iText, a Java library used to create and manipulate PDF's. I studied the iText API and found out how to make a copy of the PDF with the copy/paste restrictions removed. I wrote some code to try it out, and lo and behold, I was able to copy and paste from my custom copy of the ebook.
I figured that just like I needed to remove those restrictions, many others out there probably had the same problem. I turned my home grown utility into a web application and posted it on my site: http://www.ensode.net/pdf-crack.jsf. It has been helping people remove those annoying restrictions for a while now.,

Monica,
The utility will not be able to unlock a PDF if a password is required to read it.
If you really need to prevent recipients of your PDF from printing and/or copying/pasting you could password protect it.

Emily,
I had to limit the maximum file size to 5MB because of bandwidth concerns.
There are some products that will unlock a PDF of any size, however as far as I know none of them are free.

The utility does not keep a copy of the uploaded PDFs.
The file name and size of each PDF are logged, but the actual PDFs are not kept.

,I had to implement the 5 MB limit for bandwidth reasons. I would easily go over my allowed bandwidth limit if I allowed PDF files of any size to be uploaded.
There are tools out there that will unlock PDF files of any size, however as far as I know none of them are free. Also I have never tried them, therefore I can't guarantee their quality.

Jags,
I wish I could allow files of unlimited sizes to be unlocked, unfortunately I can't do it because of bandwidth concerns.
There are other tools you can use to unlock your PDFs, however as far as I know none of them are free and I haven't personally tried them therefore I don't know how effective they are.

Posted by Alice on February 25, 2009 at 03:00 PM EST #
its a great concept but it didn't work for me. the new pdf wouldn't open in a pdf viewer; it opened in quicktime. i have a mac so i don't know if that affected it somehow. also, it only unlocked the first page of my pdf!
Posted by sarah on February 26, 2009 at 01:39 AM EST #
PDF unlock is not working with PDF files protected by an online stored password. Tested today.

Hello,
Awesome !!!
You can't imagine how you helped me!

Whitelegend,
You are correct, the utility is written in Java.
I am unable to provide the source code, but any competent Java programmer should be able to figure out how to do it.

Hi David,
Thanks for this nice utility - I've used it a couple of time before.
Is there any way to get past the 5MB file size on your site? I've got a couple of files at about 6MB and won't go through.
Cheers,
Matt
Posted by Matt on March 09, 2009 at 06:46 PM EDT #
Dave,
Any possibility you can help out with files that are less than 6MB... I have two files, both just over your limit.
Thanks in advance.

Hi - just wanted to say thanks for making this so easy. I spent hours searching how to crack the security on a pdf file..and your's took no effort at all (when i finally found your website!) =) I'm not the sharpest tool in the shed when it comes to these types of things, and must admit,i didn't think it would work. You are wonderful.
Much appreciated.

WOW!!! I sincerely apoligize... I just went back and tried again,I realized I forgot to check the terms and conditions box and wah-law:-) This is amazing, worked like a charm. Thanks A LOT:-) and like another poster mentioned "It unlocks the whole PDF!" not just the first half(completely useless) YOU ROCK!!!
Posted by Newbie on March 26, 2009 at 12:31 AM EDT #
Just used the utility for the second time--such a lifesaver! One note--in the new file, I still wasn't able to extract pages, which is what I'd wanted to do. I was able to get to the same result by deleting pages, but thought I'd point it out in case it's an easy thing to remedy (but if not, no big deal--it's still an awesome utility). Thanks again!

Dear David,
I used your tool to remove copy restrictions from 19 PDF documents. I don't know why the Unicode Organization locked their charts in the first place. (eg. http://unicode.org/charts/PDF/U0000.pdf )
You should import and use the java.util.zip.zipfile core package to allow users to decrease the file size of their uploads. For example I zipped the 19 PDFs together and only got a 1MB file back. This would have saved you some bandwidth.
Thanks for your handy web application,
3ICE
p.s.: HTML Syntax for posting links seems to be broken. <a href="http://unicode.org/charts/PDF/U0000.pdf">http://unicode.org/charts/PDF/U0000.pdf</a> turns into . http://unicode.org/charts/PDF/U0000.pdf&quot;>http://unicode.org/charts/PDF/U0000.pdf linking to http://ensode.net/roller/dheffelfinger/entry/%3Ca%20href=
Not sure why it didn't work; I watched the progress bar as this decoded a 2mb file, then a new window opened just like the first one where I entered the original file, not a window with an unlocked document.
Posted by Jeff on May 10, 2009 at 12:41 AM EDT #

Great and helpful utility!
I needed to print 10 pdf files that were secured. I quickly found your utility through google and am so glad that I did! It worked perfectly and now I can read my required work instead of having to read it in front of the comp!
I will be highlighting your utility on my blog soon as well. :)
Also, a suggestion. Why dont you make it so that we can unlock multiple files at once? I had to convert each pdf file separately which was time comsuming. Total filesize was about 1.5mb though.
Thanks a lot David!
I needed to copy and paste some text into a word doc from a locked pdf and your utility worked perfectly. Many thanks!

I've tried your PDF unlock utility countless times and each time the result is a file that is not opened in a browser window, as advertised, but, instead, becomes a *.jsf file on my desktop. I can open the *.jsf file with Adobe Acrobat and Reader but that is all I can do because the *.jsf file remains password protected. I figure the glitch is me: please, any help will be appreciated.

Posted by pmnger on July 30, 2009 at 10:18 PM EDT #
pmnger,
The utility does not keep a copy of the uploaded files, as a matter of fact, it is processed in memory and streamed back to the browser so it never touches the server's hard drive.
Unfortunately there is no way I can get your file back.
Good Luck,
David
Posted by David R. Heffelfinger on July 31, 2009 at 07:51 AM EDT #

I can put your name and host it in my server if you wish, without any file size or restrictions. Please do contact me as your script helped me a lot, I want to help you too!

Hi! I would like to know more about this applet... I'm pretty interested due to a files, security and encryption investigation I've been doing in my college with the goal of making a thesis about it.
I've found no info about PDFs, Adobe surely will not release any info about how their PDFs are made and structured, and every person I've found that made a way to crack PDFs or made a program to do it wants to get payed for their software and surely will not release any info.
Posted by Kev Smith on October 22, 2009 at 04:04 AM EDT #
I would like to know if your source code is available, or Open Source, whatever, otherwise, I would appreciate if you could send me any info about the structure of the PDFs, what does exactly this program... like modifying determined bytes, etc... where to found the hash keys of the file (I have pdfcrack, -Open Source- so, I know there's a way to get them) anything that would help... you know.
Thanks in advance!
Your app rules!! Really awesome, efective and quick!
Let me know if you have any info, please!
Thanks!

Hmm, your program unfortunately doesn't seem to work on this one :( I wonder if it'd be hard to make a program that automatically OCRs the text out of the PDF.
Posted by Vladimir Ivanov on November 08, 2009 at 06:25 PM EST #

Thank you so much.
I am taking a certification exam and realized that the perfect handbook was available to use as it is an open book exam. I realized this too late to order it and receive it by mail and of course no stores carry it.
The ebook had no printing or copying allowed. I don't know what I would have done without you! I can't afford the full pay versions and the downloadable free versions scare me.
I graduate college in 1 week and will hopefully get a job based on passing my certification exam. I don't think I will be able to pass it without having a physical version of the handbook.
Thank you so much, when I get that job I will be back to donate!

I have found http://www.pdfunlock.com to unlock many files that remain locked after trying this site, especially newer PDFs. PDFUnlock! also removes all restrictions from password protected PDFs if you know the password. And the maximum file size is greater too.
Hi David,
Is there a file size limit? It's failing with a 10MB pdf I have. Incidentally, I think in phrases like "... copying and pasting or printing it's contents[,]" the spelling should be "its."

This is a great service you offer, unfortunately I was unable to use it because you require the user to allow you to open the unlocked pdf in their browser.
Some of us prefer to NOT allow a pdf to open in browser because it's a security risk.
A much better option would be to allow the user to save the pdf first, and then open it in browser, if s/he chooses.
