What is the Protect PDF tool?
A PDF with no password can be opened by anyone who gets hold of the file — attached to the wrong email, left in a shared Downloads folder, or forwarded further than intended. This tool adds an open password to a PDF up to 50MB, so the file itself won't display at all until the correct password is entered, no matter how many hands or inboxes a copy passes through.
How to Use It
Upload your PDF, type the password you want to protect it with, and click Protect PDF. The file is processed on a secure server and the password requirement is applied to the PDF's own structure, so it works in any standard PDF viewer. Once processing finishes, download the protected file and share the password with the recipient through a separate channel — not the same email the file was sent in.
When to Use It
Use it when emailing a payslip, tax document, or bank statement, sending a signed contract that shouldn't be opened by whoever it gets forwarded to, or archiving personal documents like passports and ID scans on a shared or cloud drive where others might browse the folder.
Who Benefits
HR and payroll staff sending payslips, accountants sharing tax documents, and anyone emailing sensitive personal or financial paperwork gets a straightforward way to keep a file private in transit without learning encryption software or paying for a dedicated security tool.
