Secured PDF will not print or copy? Turn it into a normal PDF

A PDF that opens but will not print or copy has a permissions password, not a real lock. Why Print to PDF fails on it, and how to remove it without a password.

If a PDF opens without asking for a password but will not let you print it or copy text out of it, it has a permissions password, and you do not need to know that password to remove it. The restriction is a set of flags that your PDF viewer chooses to obey. Rewriting the file without the flags gives you a normal PDF, identical in every other way.

This is the most common “locked PDF” there is, and the most commonly misdiagnosed. The file is not broken, and it is not really locked. It is asking politely.

What “secured” means on a PDF

Acrobat and Acrobat Reader put (SECURED) in the title bar of any PDF that has security settings. That word covers two different things, which is where the confusion starts.

A file that asks for a password before it opens has an open password. The content is encrypted with a key made from that password, and without it nothing can show you the pages.
A file that opens normally, then greys out Print or Copy has only a permissions password. It is encrypted too, but with a key made from an empty password, which every viewer tries automatically. The restrictions are a separate list of switches.

If yours is the first kind, this post is not the one you want. Try forgot a PDF password instead, or, if the file came from a bank, the password for your bank statement PDF.

If yours opens, read on.

The switches a permissions password can turn off

The PDF specification defines a short list. A file can switch off any combination of them.

Permission	What turning it off does
Print	Print is greyed out, or the viewer prints blank pages
Print at high quality	Prints, but at low resolution
Modify	No editing of the content
Copy	You cannot select and copy text or images
Comment and fill forms	No annotations, no typing in form fields
Fill forms only	Forms work, comments do not
Assemble	No inserting, deleting or rotating pages
Extract for accessibility	Screen readers may be blocked from the text

That last row matters more than it looks. A PDF that blocks accessibility extraction can shut out a blind reader using a screen reader, which is a good reason never to switch it off on a file you make.

Why Print to PDF does not work here

The workaround everyone knows for removing a PDF password is to open the file, choose Print, and save the output as a new PDF. On a file with an open password this does work, if clumsily, because your viewer has already decrypted the document to show it to you.

On a secured file that forbids printing, it cannot work, for the obvious reason: printing is the thing that is switched off. Any viewer that respects the flag greys out Print, and Save as PDF lives inside the Print dialog. The one trick people know fails on precisely the files they most want it for.

Even when it does work, printing to PDF is not the same as unlocking. It redraws every page into a brand new file. Bookmarks, internal links, form fields and the document’s own metadata do not come through, and on some systems the text comes out as pictures of text that can no longer be searched or copied, which rather defeats the point if copying was what you wanted.

Taking the restrictions off properly

The clean way to turn a secured PDF into a normal one is to decrypt it and write it back without the security entry. Nothing is redrawn. Every page, every font, every bookmark and every form field comes out exactly as it went in, and the restrictions are gone because the thing that stored them is gone.

Here is how, in order of convenience.

In your browser, with nothing installed

Drop the file into our unlock tool. It checks the lock before it asks you for anything. If the file opens without a password, it says so, the password box is switched off, and one click gives you the unrestricted copy. The file stays on your device, and nothing is uploaded.

With Acrobat, if you have the permissions password

If you do know the permissions password, the full version of Acrobat can remove it. Open Protect a PDF, then Set security properties, choose Change Settings on the Security tab, and clear “Restrict editing and printing of the document”. Acrobat Reader cannot do this.

On the command line

The open source tool qpdf does this with one command, and it is what our tool runs underneath, compiled for the browser:

qpdf --decrypt secured.pdf normal.pdf

No password argument is needed for a permissions-only file, for the same reason your viewer does not ask for one.

Is it all right to remove the restrictions?

The restriction flags describe what the author would like you to do with the file. The PDF specification is explicit that nothing in the encryption enforces them, and asks software to respect the author’s intent. Removing them is ordinary and widely supported, and it does not mean the author’s wishes stop applying. qpdf’s own manual makes the same point: decrypting is not a way around copyright.

The fair test is whether you already have access to what you are unlocking. If you can open the document and read every page on screen, you can already see all of its content, and removing the flags only lets you print or copy what is in front of you. Copyright, confidentiality agreements and your organisation’s policies apply to the content the same way whether the flags are there or not.

What removing the flags does not do is open a file you cannot read. If a password prompt appears before the first page, that is real encryption, and there is no way around it without the password. Our tool does not attempt one.

If it is your own PDF

If you are the one making the file, think about whether a permissions password is doing what you want. It will stop a casual reader printing your document. It will not stop anyone determined, as this whole post shows, and it will stop some people with a legitimate need, such as someone who has to print a form to sign it, or a colleague who uses a screen reader.

If the goal is to keep the content private, you need an open password, which is real encryption. If the goal is to mark a document as final or confidential, a visible watermark does that job without breaking printing.
