Protection Settings

User Password (Required) Users will need this password to open and view the PDF. They will NOT be able to print, copy, or modify the document.

Owner Password (Optional) Use this password to open the PDF without any restrictions (can print, copy, and modify). Leave empty and a random owner password will be generated automatically.

Password Protection Tips:

User Password: Required to open and view the PDF
Owner Password: Required to make modifications (printing, copying, editing)
Use strong passwords with mix of letters, numbers, and symbols
Passwords are case-sensitive
Don't forget your passwords - encrypted PDFs cannot be recovered without the password
Keep your passwords secure and don't share them publicly

How it works: Your PDF will be encrypted using industry-standard encryption (256-bit or AES). The original content and formatting are preserved. All processing happens securely on our servers and files are deleted after processing.

📝 Frequently Asked Questions

What's the difference between User and Owner passwords?

User Password: Required to open and view the PDF. When opening with the user password, users cannot print, copy text, or modify the document - these operations are restricted.

Owner Password: Bypasses all restrictions. Use this password to open the PDF with full permissions (printing, copying, modifying, etc.). If you don't provide an owner password, a secure one is automatically generated.

Are my files secure?

Yes, we use industry-standard encryption to protect your PDFs. Files are processed securely on our servers and automatically deleted after conversion. We don't store or access your documents.

What if I forget the password?

Unfortunately, encrypted PDFs cannot be accessed without the correct password. There is no recovery method once a PDF is encrypted. Store your passwords in a secure location.

Can I protect multiple PDFs at once?

Currently, you can protect one PDF at a time. If you need to protect multiple files, you can repeat the process for each file.

What encryption method do you use?

We use AES-256 bit encryption, which is the same level of security used by government institutions and banks.

Can I remove the password later?

To remove password protection, you need the owner password. Then you can use PDF viewer tools to remove the protection if needed.
