What is the PDF Password Protector?
The PDF Password Protector encrypts a PDF with an open password so that anyone who receives it must enter the password before they can view the contents. The encryption runs entirely in your browser — your file is never uploaded to a server.
Use it to protect sensitive documents — contracts, payslips, personal records, or confidential reports — before sharing them via email or cloud storage.
Who Is This Tool For?
- Business professionals — protect confidential reports, contracts, and financial documents before emailing them.
- HR teams — secure payslips, offer letters, and employee documents before distribution.
- Legal and compliance teams — add password protection to sensitive client documents and filings.
- Students and researchers — protect original work before sharing it with reviewers or examiners.
- Anyone — add a basic layer of protection to a personal document sent via an unsecured channel.
Common Use Cases
- You are emailing a contract or NDA and want the recipient to need a password before viewing it.
- You are sending a payslip or tax document and want to protect it with a password shared separately.
- You are submitting a confidential research document and the submission system does not encrypt uploads.
- You are sharing a PDF via a public link (e.g. cloud storage) and want to add password protection.
- You want to store sensitive personal documents in cloud storage with an extra layer of protection.
