I am trying to fill out some docs, but the provided PDFs are "SECURED", meaning I can't use FoxIt's typewriter tools.

Is there any way to remove the security?

Contrary to the other solutions, you do not need additional software.

Anyone with Windows can do it with no extra software in 4 simple steps.

  1. Open the PDF
  2. Go to File > Print. From your print options choose Microsoft XPS Document Writer. Although you might expect it to print, it does not print anything, it will create an XPS Document.
  3. Open the resulting XPS file
  4. Press Print, go to Microsoft PDF Creator. It will now save it as a PDF again. Again, it will not print.

In my case I had to remove the first/last page of a document so I only printed the pages required.

    I love this idea and worked for me. Only issue was the quality change in conversion to XPS and back to PDF. It would be just specific to my document, though.

  • Interesting, I have also found the MS PDF creator to be a bit pants. I use the Adobe PDF creator, although I believe it came with Adobe Creative Suite so not everyone will have a copy (could be wrong).

    This approach worked for me, by opening it in Chrome, printing, choosing 'Print to PDF' and then opening the outputted PDF. Commented Aug 31, 2016 at 3:17

    The major downside of this is that you cannot mark or copy text anymore.

    @basseur If the text was OCR'd text in images then just re-run Acrobat's OCR on the unprotected PDF and re-save it with the recognized text.

Assuming it's simply a 'rights' (owner) password that restricts things like editing, printing, and copying (i.e. the password does not need to be entered to open the file) the following will remove the restrictions:

  1. Grab https://github.com/qpdf/qpdf/releases
  2. Unzip/Install and navigate to the bin folder that holds qpdf.exe (or similar for your platform)
  3. Place the PDF you wish to work on in the same folder
  4. Run: qpdf --decrypt InputFile.pdf OutputFile.pdf (use "s if the file name has spaces).
  5. Do what you like with the OutputFile.

If your PDF file is user password protected, change step 4 to qpdf --decrypt --password=yourpassword InputFile OutputFile

This won't work for Adobe Digital Editions and may have issues with digitally-signed files.

  • I had to use qpdf then PDFcreator to enable edits on one PDF document. (PDFcreator without qpdf first wouldn't work). It was a document both password-protected and certified. Using the save as .ps trick didn't work. (I couldn't compare against unlock PDF websites as the document was confidential.) Commented Jan 11, 2017 at 17:57

    As of March 2nd 2022 qpdf + PDFcreator still works, even for "certified" PDFs. Critically, it doesn't rasterize the text (like the Microsoft "Print-to-PDF" solution does for certified PDFs. Commented Mar 3, 2022 at 0:44
  1. Print to a PostScript (PS) printer (where the printer's port is set to print to file, not to the printer -- or check the "Print to file" option in the Print dialog)
  2. Edit the resulting .ps file and remove:

    mark currentfile eexec
  3. Save and distill the .ps file

Using google chrome offline (without uploading anything)

It's a slightly old thread but as I use this often, I wanted to update it:

  • Simply drag and drop the PDF in question on a blank chrome page.
  • Chrome opens the "locked" PDF.
  • Now print the document and use "save as PDF" as the printer of choice.
  • Enjoy your perfectly conserved and unlocked PDF (esp. copy & paste ;-) )

The "print"->"save as" step can be tricky when you do it the first time, as you might choose the PDF Writer/Maker for output and you will end up with a locked PDF again.

The process is further described here: Save As PDF

On some versions of chrome (older?) you have to activate the "save as PDF" option first.

As you can install chrome without giving them your email address, I would consider this a truly "free" solution.

Directly (see and) remove the restrictions from your pdf without any tricks:

1- Online method:

If you want to do in your browser (without installing a tool), then use PDFUnlock. You just need to upload your pdf (drop it to the available box) and it removes the security restrictions. However, up to 5MB files are converted for free.

2- Offline method:

But, like me, if you prefer having an offline tool on your machine, then you can install Weeny Free PDF Password Remover.

  1. From the full version of Acrobat (I used v9.3), select "File..Export..Postscript..Postscript". This creates a ".ps" file.
  2. Click on the .ps file, it converts it back to pdf automatically with Acrobat distiller.
  3. You now have a perfect copy of the original file, minus any signatures, restrictions on editing, etc.

I needed this technique fix the pdf file so it would display on my Kindle DX, via the "Advanced..Preflight" menu. This method worked perfectly on a file that had resisted all attempts by the four major utilities that offer to remove restrictions on pdf files (i.e. A-PDF, pdftk, Kernel PDF, UnrestrictPDF) .

    Nope, this didn't work for me... Got this error: This PostScript file was created from an encrypted PDF file. Redistilling encrypted PDF is not permitted. Looks like they caught up with this trick.

I upload it to google drive with chrome, hit the print button and save it as pdf (which has to be enabled within chrome settings on some versions). I get the real deal, images are same resolution, file size checks out too, but all the security restrictions are gone.

Also removes printing restrictions from files. (Credit @Rob)

Beware! Also removes bookmarks and links. (according to @Barleyman)

Thanks Google! You guys are hackers :-)

    Yeah, I would also be very interested. As a matter of fact, I had some tricky PDFs with images and vectorgraphics and I tried all "free" solutions (most of them aren't really free, it's mostrly trials and crippleware) and none of them worked. Maybe the purely commercial ones are so much better (don't forget, the Microsoft XPS Document Writer is the contrary of free and you better habe a valid MS License whe you export it, as it will be in your resulting PDF, along with your name and other "useful" stuff.) Then I tried the google way and it worked like a charm for all PDFs so far. Commented Sep 1, 2016 at 22:00

Building on Dan's answer, here's the full bash for OS X/Mac

#! /bin/bash

brew install qpdf

for file in *.pdf
    echo "Removing password for pdf file - $file"
    qpdf --decrypt "$file" "decrypt.$file" --password="$PDF_PASS"

My 20-page tax form ballooned to 70MB when I removed the password through a PDF-printer. But then I tried using PDFsam Basic, a free tool that I usually use for splitting and merging pdfs.

To my surprise, it handles password-protected PDFs well and, when exporting the document, removes the password protection without increasing the file-size.

In fact, the file-size decreased by a few kB.

  • Yup, works beautifully. And it keeps links and bookmarks intact. Just export pages '1-' and you're good to go.

you can use PDF CPU:

pdfcpu decrypt in.pdf out.pdf


note that it actually resulted in a smaller resulting file for me, versus QPDF:

original QPDF PDF CPU
5,406 KB 5,339 KB 4,617 KB

Analog conversion. Print and re-scan.

  • Hmmmm ... even if you wanted to go that way, isn't it easier to just "Print to PDF" from the full version of Acrobat? However, this ruins the margins, so you get a perfect conversion if you export to Postscript, then reimport to pdf (see my answer below)?

Removing user/open password is next to impossible, but if your PDF file is only protected with owner password, i.e., PDF print, edit, copy and other functions are disabled then there are several programs available to remove PDF security like the one mentioned in this article: http://www.instructables.com/id/How-to-Remove-PDF-Password-Security-PrintEditCo/

Due to security and privacy reasons I would not recommend those online services where you’re supposed to upload your PDF documents to remove PDF security.


On Windows 10, you can just :

  1. Open the document
  2. "Print" the document by selecting "Microsoft Print to PDF" printer

That's it! the protection is removed and you can still select the text in the document.


In my case, there was a view password that maintained its state through save -- but print, etc. were not blocked. That left open the analog method, or print-to-PDF-printer, which is what I did. The resulting file lacked a password, and seemed to suffer no degradation.


You may simply use iLovePDF's "Unlock PDF" tool :

  1. access the website;
  2. select and upload your file(s);
  3. click "unlock PDF";
  4. click dDownload unlocked PDFs";
  5. voilà!
