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.,

thanks for this nice utility.. It managed to crack the password for the full pdf file..Unlike those trial version which can only crack half of the pdf file.

No problem, glad to hear you found the utility useful.

Posted by David R. Heffelfinger on October 16, 2008 at 09:05 AM EDT #

thank you so much for this utility, I am now able to print and read the pdf in paper form that my instructor gave me for class, so I can highlight key terms and whatnot.

Thanks man, works like a charm

thank you for providing a really helpful tool! I really appreciate your work and effort to provide this. blessings, rev jarrett

A while back, I searched to web to try to find a way to print some PDFs that were locked. I wanted to use them in my second grade classroom. Couldn't find anything that didn't involve spending money (without the guarantee of really knowing it would work). Tonight I decided to do a search again after straining my eyes trying to read on my computer screen and found a link to your service. THANK YOU SO MUCH. I will return. Again and again. How long will you provide this wonderful service? :)

Liza,

Nice to hear you found the utility useful.

I plan to offer this utility for years to come.

Dear Sir, You do not know how you have helped me greatly! This program has saved my life, and I thank you greatly. I hope that you provide this utility for a long time. Sincerely, Alexis Omar

Thank you SO much for creating this tool. I just wanted a simple way to unlock a pdf to print it (once!) for my own convenience. I wouldn't try to use it to mass-print documents, etc., it just helps to be able to print out instructions and docs like that. Thanks very much! MW

This utility rules! My university has these PDF forms that I have to fill out each time I submit a proposal to a funding agency. However, they lock it so I can't sign it electronically, and have to print, sign and scan the documents each time. Not anymore! Thanks!

Great !! Thanks for sharing this.

I'm so thankful. I've tried to do everything to print these important info. 'If I can't get it, my report won't be completed. It's very very helpful, your program. I'm grateful.

David, This is truly a great service you are providing. Is this code that you wouldn't mind sharing? If nothing else, in case you get shut down, if the code was out there it would help keep this utility alive. AT

Posted by andrew on November 29, 2008 at 12:14 PM EST #

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.

I have two files larger than 5M (one is just over 5M and the other over 9M) any help for these? I've tried your utility without success. Thanks

Posted by Emily on December 01, 2008 at 05:20 PM EST #

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.

Posted by Adriana on December 05, 2008 at 07:20 AM EST #

David, Do you store copies of all of the PDFs uploaded?

Posted by no-one on December 09, 2008 at 03:45 AM EST #

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.

A GREAT BIG THANK YOU! Your FREE Utility worked fabulously. Unfortunately before I found it I paid some of my hard-earned cash to buy a utility from www.unlock-password.com and not only did it not work at all - the software that was promised was not the software that was delivered.... "guaranteed" my eye! Money back - yeah - I'm still waiting for hell to freeze over..........

Posted by dinesh on December 23, 2008 at 11:57 PM EST #

man, yuor program is simply awesome, but there is a LITTLE problem...why only just 5 mb is the limit?because I work doing translations and I can't unlock some docs, then I HAVE TO tipping...all. Man that's the only complain of this awesome tool, if you can extend the size's limit it would be great bye

Posted by marlon on December 29, 2008 at 09:18 PM EST #

Marlon

,

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.

Posted by R. Seeberger on January 14, 2009 at 01:05 PM EST #

Could you increase the size limit of the PDF document unlocking please. I have a document size of 10mb and I am not able to unlock it.

Posted by Jags on January 16, 2009 at 10:19 AM EST #

This is just what I have been looking for, it works!!! and its free!!!!!! ~ Life safer thanks so much!!

Posted by W on January 16, 2009 at 07:02 PM EST #

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.

The PDF file that I need unlocked is 400 pages long, and about 10 MB. I cannot even extract the pages and split it into 3 parts. If I could do that, would be totally awsum. Is there any way that I can get it unlocked? That will save me a whole bunch of trouble. Thanks for the effort you've put into making this utility. Imran

Posted by Imran on January 25, 2009 at 03:23 PM EST #

Sorry, but your utility didn't work: I submitted a locked-for-saving-data form, and it came back still locked-for-saving-data. ? Amir

Posted by Sam on February 06, 2009 at 12:34 PM EST #

Could you name some of the commercial appz that unlock secure pdf files? I searched around on google, but the results were not great.

Posted by Mookey on February 09, 2009 at 12:18 AM EST #

Mookey,

Although I know some comercial tools exist that claim to be able to unlock PDF files, I don't have personal experience with any of them, therefore I can't make any recommendations.

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,

You can't imagine how you helped me!
I have one question anyway... please don't be hurt by my request but i want to know if it is possible to get the source of your program?
I imagine that you wrote your project under java devellopement...

Please let me know, i will give you my email in case of you will agree to my request.

Thank's a lot anyway for you helpfull link.

Posted by Whitelegend on March 02, 2009 at 09:16 AM EST #

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 #

Any possibility you can help out with files that are less than 6MB... I have two files, both just over your limit.

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.

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!

I have a 6.6Mb PDF file, would it be possible to raise the file size limite shall we say to 10mb?

:)

thanks,

Gizmo

Thank you very much, this application is really worthy. It helped me to extract important info from several public PDF's that shouldn't be password protected. Imagine a state law PDF that it's not allowed to be printed, mind you.

Great blog by the way.

I had been searching for something to be able to print something in PDF format that had a password on it. I was breaking my back sitting at the computer all day trying to read it. Your site worked perfectly. Made a donation to say thanks!!

Posted by gagirl555 on May 01, 2009 at 04:27 PM EDT #

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&amp;quot;>http://unicode.org/charts/PDF/U0000.pdf linking to http://ensode.net/roller/dheffelfinger/entry/%3Ca%20href=

Posted by 3ICE on May 08, 2009 at 04:35 PM EDT #

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 #

wow.... a work of art. I wanna xpress my gratitude for cutting my work in half. I've been using the beta for almost 2 yrs and i tell you this is amazing.

Once agian thank you...

Just what I needed - So simple - Thanks a bunch

Posted by Gail on May 11, 2009 at 03:19 PM 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!

Posted by Fahad on May 12, 2009 at 04:22 AM EDT #

I needed to copy and paste some text into a word doc from a locked pdf and your utility worked perfectly. Many thanks!

I wanted to translate a locked house rental contract from German to English using BabelFish...

Tried printing to OneNote 2007 and using it's OCR to extract the text, but it's only about 80% accurate, your site worked great!

Thank you

Posted by Gabriel on May 16, 2009 at 12:33 PM EDT #

You have a great utility. Is there any chance you can expand the size limit to say 10mb? Most PDFs are large these days and it would be great if you can expand this size limit.

Posted by Tom on May 17, 2009 at 12:08 AM EDT #

Thanks David

Posted by Eduardo on May 17, 2009 at 09:03 PM EDT #

I like the ideas of accepting zipped PDFs and allowing multiple simultaneous uploads.

Unfortunately I'm quite busy at the moment so I can't implement them right away, but I'll keep them in mind.

Great concept...does not work. simply re-opened a new browser window with the same URL, after taking forever to attempt whatever it was attempting...no error message, nothing. Thanks for the try, nonetheless.

Posted by Mark on May 19, 2009 at 10:52 AM EDT #

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.

I'm on a MAC with ver. 10.5.7

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

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!

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.

Posted by Niederman on December 29, 2009 at 01:39 PM EST #

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.

Posted by Orly on March 03, 2010 at 09:42 PM EST #

I find this utility really helpful! It doesn't install anything on my computer and delivers what it promises. When I need to open a bigger file, I will go for PDFUnlock, but this site works perfectly for most of my files. Thanks David for all the troubles you have saved us!

Thank you for your application. Its perfect and fast. If I had to criticize something, I would mention the file size restriction to 5 MB. For those who want to unlock files up to 10 MB for free, go to http://www.pdfunlock.com/. However, I recently found a free installable application for the computer (Freeware PDF Unlocker) available here (http://www.gratisprogramas.org/descargar/freeware-pdf-unlocker-104/ ) which allows you to unlock full pdf files of any size. You dont need to pay money for unlocking big pdfs ;)

I was trying to use your utility to copy from a pdf document in order to translate it to English so that I could read it but although the copy property changed to allowed I still couldn't select anything in the document. :-(

Ha.. I'm reading through Java EE 5 Dev. Using GlassFish when I get a call from my brother who can't print from a PDF. I do a quick search and find a great little 'unlock' utility written by none other than David R. Heffelfinger, author of Java EE 5 Dev. Using GlassFish. The world is indeed a miniscule place.

You really challenged me with "...any competent Java programmer...".

I didn't make it. I guess it is because my PDF is marked as "(secured)" in the title bar of Adobe Reader.

iText forum definitely says: "without owner password: not possible".

Or do you start a brute force password attack...?!!?

Now I use pdf2ps + ps2pdf (just like pdfpirate.org), but this doesn't require iText.

Thank you for the wonderful help. I have a problem, though. When I saved the file after using the unlock utility, it was in .jsf
I couldnt open it after I saved it. Is there a way to convert it to a pdf file? Sorry about this but I am not really a techie person.
Thank you very much.

Hello,
Just wanted to say thank you for making this available for free online. When I can afford to donate, I most certainly will; I am never interested in stealing anyone's intellectual property but it's impossible to make small corrections for errors I find in a lot of .pdf files, as well as to make notes, or even find a way for ease of opening.
I bought a huge one where you need the photo that goes with the diagram, but all the photos are in the front and the diagrams in the back...so I was constantly jotting page numbers all over me and my room, trying to flip between photo and diagram because I didn't need to print it out...4 photos to every page anyway, and only 1 diagram.
So your converter has made my life simpler when I am on the pc [which is every day].
You're a star.
Many thanks,
Jo.

I used this site once before and it really worked great. Thank you!

However, this time it is generating *.jsf files which I can not use. I use a reader that reads form the copy buffer... Anyway, has this changed (from generating pdf to jsf)?

If there is a way for me to get the pdfs that would be wonderful.

My need is to merge some files into a single document to load to my Kindle, which doesn't handle a large number of files very well. The files I wish to merge show 'Allowed' for all types of permission after processing them through this utility, but Acrobat wants a password for merging. The files are 40-bit encrypted. This is just another example of mindlessly applying security settings without understanding the consequences to the users.
