About This Tool
Security is paramount when sharing sensitive documents like bank statements, legal contracts, or personal ID proofs. The Protect PDF tool allows you to encrypt your document with a strong password using industry-standard AES 128-bit encryption. Once locked, the file cannot be opened, printed, or modified without the correct password. This ensures that even if you email the file or store it on a shared drive, unauthorized users cannot access its contents. The entire encryption process runs locally on your machine, so you never have to worry about sending unencrypted sensitive data over the internet. This tool processes files locally in your browser whenever possible, ensuring your sensitive documents remain private and secure. Unlike many online PDF tools that upload your files to remote servers, we prioritize your data privacy. The tool handles large files efficiently and maintains the original quality of your PDFs without compression or degradation. Whether you're a student compiling research, a professional preparing reports, or a business managing contracts, this tool streamlines your PDF workflow. It eliminates the need for expensive Adobe Acrobat subscriptions while providing professional-grade results instantly.

Frequently Asked Questions
Can I recover the password if I forget it?
No. The encryption is secure. If you lose the password, there is no way for us (or anyone else) to recover the content effectively. Please remember your password.
Can I remove the password later?
Yes, if you know the password, you can use our 'Unlock PDF' tool to permanently remove security.
How strong is the encryption?
We use 128-bit AES encryption, which is the standard for PDF security and very difficult to crack without substantial computing power.
Does this prevent printing?
By default, the password prevents opening the file. Once opened, typical viewers allow printing, though some security settings can restrict permissions.
