Whether it's a contract, a payslip, medical records or a confidential report, password‑protecting a PDF means only people you share the password with can open it. PDFNest encrypts your file right inside your browser, so neither the document nor the password is ever uploaded to a server.
Because the encryption happens locally, your password is never transmitted or stored anywhere — which also means we genuinely cannot recover it if you forget it, so keep it safe.
Yes. The protected PDF requires the password before it can be viewed in any reader.
No. Encryption happens entirely in your browser; your password and file never leave your device.
It can't be recovered — by design, no one (including us) has access to it. Store it somewhere safe.
