Add a password to any PDF file in seconds. This free online tool lets you set an opening password so only people with the password can view the document. Optionally restrict printing, copying, and editing with five independent permission controls. No uploads to servers — your file stays on your device throughout the entire process. Adding a password is the simplest and most effective way to control access to a PDF document. Once you set a password, the file is encrypted with AES-256, and anyone who tries to open it must enter the correct password first. You can also set a separate owner password that grants full control over the document, allowing you to change permissions or remove the password entirely while keeping the user password in place for recipients.

## How it works

1. **Upload PDF** — Select or drag and drop the PDF file you want to protect with a password.
2. **Set Password & Permissions** — Choose a strong password and configure what actions are allowed — printing, copying, modifying, annotating, and filling forms.
3. **Download Encrypted PDF** — Get your password-protected PDF instantly. Everything runs in your browser — no server uploads.

## Use cases

- **Secure File Sharing**: Add passwords to shared documents in cloud drives and collaboration platforms for an extra layer of security beyond the platform's access controls.
- **Protecting eBooks**: Password-protect digital books and manuscripts to prevent unauthorized distribution. Restrict copying to prevent text extraction for piracy.
- **Client Proposals**: Add passwords to pricing proposals and quotes before sending to prospects, ensuring competitors cannot access your pricing strategy if emails are forwarded.
- **Board Reports**: Protect quarterly reports and board presentations with passwords before distributing to board members, ensuring confidentiality of financial data.

## Tips

- **Share Passwords Securely**: Never send the password in the same email as the PDF. Use a separate channel like a text message, phone call, or encrypted messaging app to communicate the password.
- **Consider Permissions**: If you want people to read but not print or copy, uncheck those permissions before encrypting. This is useful for sensitive documents that should only be viewed on screen.
- **Test on Multiple Devices**: After adding a password, test the encrypted PDF on both desktop and mobile devices to make sure the password prompt appears correctly on all platforms your recipients use.

## FAQ

### Can the recipient remove the password?

Only if they know the owner password. With just the user password, they can only open and view the file within the set permissions — they cannot remove or change the password.

### Does this work on mobile?

Yes, the tool works in any modern mobile browser. Upload, set a password, and download the protected PDF directly on your phone or tablet.

### Can I add a password to a scanned PDF?

Yes. The encryption works on any valid PDF file regardless of how it was created — scanned documents, digital files, forms, or image-based PDFs.

### What happens if someone tries to open without the password?

The PDF reader will display a password prompt. Without entering the correct password, the document contents remain completely inaccessible and encrypted.
