Why Protect Your PDFs?

Confidentiality

Ensure that only authorized individuals with the password can open and view your sensitive documents.

Controlled Access

Set specific permissions to determine what recipients can do with your document, like printing or editing.

Authorized Distribution

Control who can access your document when sharing contracts, research, or intellectual property.

Document Expiration

Password protection adds an extra layer of security for time-sensitive documents that shouldn't be accessible indefinitely.

Understanding PDF Security

User Password vs. Owner Password

Password: User Password: Required to open the document. Anyone without this password cannot view the content.

Owner Password: Owner Password: Controls permissions. With our tool, we set both passwords to be the same for simplicity.

Encryption Levels

128-bit AES: 128-bit AES: Provides good security and is compatible with Acrobat Reader 7 and later versions.

256-bit AES: 256-bit AES: Offers stronger security but requires Acrobat Reader X (10) or later versions.

Permission Controls

Printing

Controls whether the document can be printed and at what quality level.

Content Copying

Controls whether text and images can be selected and copied to the clipboard.

Editing

Controls document modifications, including annotations, form filling, and content changes.

Frequently Asked Questions

What's the difference between the encryption levels?

We offer 128-bit and 256-bit AES encryption. 128-bit is compatible with older PDF readers (Acrobat 7 and later), while 256-bit provides stronger security but requires newer readers (Acrobat X and later).

Can I remove the password protection later?

Yes, you can use our Unlock PDF tool to remove password protection from your PDF files, but you'll need to know the current pdf with a password to do so.

How secure is the password protection?

Our tool uses industry-standard AES encryption. The security depends on password strength and the encryption level you choose. We recommend using strong, choose a strong password with a mix of characters.

Will password protection affect the PDF content or quality?

No, password protection only adds security settings to your document and doesn't alter the content, layout, or quality of your PDF in any way.

Can I protect multiple PDFs at once?

Currently, our tool processes one PDF at a time. For batch processing of multiple files, consider our API or premium solutions.
