Step-by-Step Instructions

4 Easy Steps
1

Upload Your PDF File

Open the Protect PDF tool and select the document you want to secure.

Pro Tip: You can also batch encrypt multiple documents with the same security settings.
2

Set a Strong Password

Enter your viewing password in the password field. Use a combination of uppercase letters, numbers, and symbols for maximum resistance against brute-force attacks.

Pro Tip: A password strength meter will guide you to ensure adequate entropy.
3

Configure Permissions (Optional)

Optionally specify whether recipients are allowed to print the document or copy text to their clipboard.

Pro Tip: Disabling text copying helps prevent unauthorized distribution of proprietary data.
4

Encrypt and Save

Click 'Protect & Save'. Your encrypted PDF will download immediately. Test it by attempting to open it in Adobe Acrobat or your browser to confirm password prompting.

Pro Tip: Always remember to share the password with the recipient through a separate, secure communication channel (e.g. Signal or SMS).

Frequently Asked Questions

Can someone open an encrypted PDF without the password?
No. Standard AES-128 and AES-256 encryption are mathematically secure against brute-force attacks when paired with a strong password.
Does iEditPDF store my passwords or encryption keys?
Never. Encryption is executed entirely inside your browser's local JavaScript/WebAssembly memory space. We have no servers storing documents or credentials.
