Security Notes
Password-Protect PDF Online — Complete Guide
Add password encryption to sensitive PDFs before email or cloud sharing. PdfPeaks lets you set an open password and optional permission limits (printing, copying) so only people with the password can open confidential files such as ID scans, payroll, and contracts.
How It Works
Upload the PDF, choose a strong password, set permission options if shown, and apply protection. Download the encrypted file and send the password through a separate channel (SMS, password manager, or in-person) — never in the same email as the attachment.
- Step 1 — Upload: Select the PDF to encrypt.
- Step 2 — Secure: Set the open password and optional print/copy restrictions.
- Step 3 — Share safely: Distribute the PDF and the password separately.
Security & Privacy
Files are encrypted in transit and deleted after processing — see our Privacy Policy for details.
Common Use Cases
- HR: Protect payroll and personnel PDFs.
- Healthcare: Encrypt patient-related exports before transfer.
- Finance: Lock tax returns and bank statements.
- Legal: Limit copying of draft agreements.
- ID & KYC: Secure scanned IDs after JPG to PDF / ID Card Scan.
Tips for Best Results
We cannot recover a lost password after encryption — store it in a password manager. To remove protection you control, use Unlock PDF. Background: how PDF passwords work.
