How to Use PDF Security & Encryption

Lock sensitive financial statements, legal records, and proprietary documents with industry-standard 256-bit encryption and granular access permissions.

1

Upload the PDF to Protect

Select or drop your PDF document into the dropzone from your computer, phone, or FolderBit Workspace Library.

2

Set Opening Password & Permissions

Create a secure password to unlock the document. Optionally toggle whether recipients are allowed to print high-res copies or copy text and graphics.

3

Encrypt and Secure

Click 'Protect PDF'. The file is encrypted using enterprise-grade AES-256 encryption. Download your protected file immediately.

Frequently Asked Questions

What encryption standard does FolderBit use?
FolderBit applies AES-256 (256-bit Advanced Encryption Standard) in accordance with the official PDF ISO specifications. It is one of the most impenetrable symmetric ciphers available.
What happens if I forget the password I set?
Because FolderBit operates with a zero-knowledge security architecture, we never store or cache your password. If you lose your password, the encrypted file cannot be recovered.
Can an encrypted PDF be opened in any standard viewer?
Yes. Any compliant PDF reader (Adobe Acrobat, Apple Preview, Edge, Chrome, Firefox) will prompt the user for the password before rendering the document pages.
Does password protection prevent someone from printing the file?
Yes. When you uncheck 'Allow printing', the security dictionary embedded in the PDF instructs compliant readers to disable the print button and print dialogs.
