When a Secured PDF Won't Print or Copy
What the restriction is, and how to lift it on a file you're entitled to use.
The Short Answer
A PDF that opens normally but won't print, copy or edit has a permissions password, also called an owner password. It doesn't stop the file opening; it asks the viewer app to grey out those actions.
If the file opens without a password, its restrictions can be removed without one. Only do this for documents you're entitled to use.
Remove PDF restrictions →How to Remove the Restriction
- Open the PDF Password Remover and choose the PDF.
- If the PDF opens without a password, leave the password box blank. If it asks for a password when you open it, type that password.
- Click Remove Password, then Download.
- Open the downloaded copy and print or copy as normal.
In our tests we restricted a PDF so it couldn't be printed or copied, with no open password. With the password box left blank, the tool saved a copy that was no longer encrypted and had no restrictions, with its text intact. A PDF that needed an open password was refused until the right password was typed in.
Please respect copyright: lifting a restriction doesn't change who owns the content or what you're allowed to do with it.
What the Restriction Actually Is
PDF encryption has two passwords. The open password (the PDF specification calls it the user password) is needed to read the file. The permissions password (owner password) lets anyone open the file but tells viewers which actions to allow: printing, high-quality printing, copying text, editing, filling forms, adding comments and so on.
When a file has only a permissions password, its contents are encrypted with a key anyone can derive, because the open password is empty. Viewers that follow the specification then hide the blocked actions. As the qpdf documentation puts it, the security of these restrictions is enforced solely by the software. Adobe's password security help says recipients don't need a password to open such a file, only to change its restrictions, and warns that some third-party products don't fully respect these settings.
Things That Trip People Up
- It asks for a password to open. That's an open password, not just a restriction. You need it; nothing here can guess it.
- Signed documents. Unlocking rewrites the file, so any digital signature in it will no longer verify. Keep the original if the signature matters.
- Certificate or server-based security. Some corporate documents are protected with digital certificates or an online rights-management service rather than a password. Those can't be unlocked with a password tool.
- Printing is allowed but blurry. A PDF can allow only low-resolution printing. That is also a permissions setting, and removing restrictions lifts it.
- You only need to sign or fill it. Restrictions can block signing too. See why a PDF won't let you sign.
How to Check What's Restricted
- Acrobat Reader: a secured file shows (SECURED) next to its name. File > Properties > Security lists the Document Restrictions Summary, showing each action as Allowed or Not Allowed.
- Any viewer: if Print is greyed out but the file opened without a password, it most likely has a permissions password.
Frequently Asked Questions
Why can't I print a secured PDF?
The author set a permissions password (also called an owner password) that asks PDF viewers to block printing. The file still opens without a password, but compliant viewers grey out Print, and often Copy and Edit too.
What's the difference between an open password and a permissions password?
An open password (user password) is needed to open the file at all. A permissions password (owner password) lets anyone open the file but restricts what they can do with it, such as printing, copying text or editing. A PDF can have either, or both.
How do I remove printing restrictions from a PDF?
If the PDF opens without a password, the PDF Password Remover here can save an unrestricted copy: choose the file, leave the password box blank and click Remove Password. If the PDF asks for a password when you open it, you need that password.
Is it legal to remove restrictions from a PDF?
It depends on the document, your rights to it and where you live, and this guide isn't legal advice. Removing restrictions makes sense for files you own or are entitled to use, such as your own statements or forms you need to print. Respect the author's copyright and any terms you agreed to.
Why does it say Secured in the title bar?
Adobe Acrobat and Acrobat Reader add (SECURED) to the title of a PDF that has security settings. In Acrobat Reader, File > Properties > Security shows the Document Restrictions Summary, listing what is allowed and what isn't.
Can a permissions password really stop copying?
Only as far as the viewer cooperates. The PDF specification leaves enforcement to the software, so the restrictions work in viewers that honour them. Adobe's own help notes that some third-party products don't fully respect these settings.
