Why Restrict PDF Permissions?

  • Protect Intellectual Property

    If you are selling e-books, research reports, or sheet music, disabling text copying and printing prevents easy piracy and unauthorized distribution.

  • Secure Legal Documents

    Ensure that contracts, NDAs, or official forms cannot be altered or tampered with after you have finalized them.

  • Corporate Compliance

    Share internal memos or financial statements with employees while ensuring the data cannot be extracted or printed outside the office.

Frequently Asked Questions

Everything you need to know

What is the difference between an owner password and a user password?

A user password is required just to OPEN the document. An owner password allows anyone to open the document, but RESTRICTS what they can do (like copying or printing) unless they enter the password.

Can someone easily bypass these restrictions?

We use strong 128-bit or 256-bit AES encryption. While no digital file is 100% immune to dedicated hackers, our permissions are strictly enforced by Adobe Acrobat and all compliant PDF viewers.

Can I remove the permissions later?

Yes, as long as you remember the owner password you set, you can use our 'Unlock PDF' tool to remove the restrictions at any time.
