Add a password to a PDF before you email it — so if it forwards or leaks, the file itself is still locked.
Protect PDF encrypts a document with a password the reader has to type before it opens. It's the last step before you email a contract, a payslip, an HR letter or a medical record to someone outside your organisation — so if the message gets forwarded, replied-all to, or lands in the wrong inbox, the attachment itself is still locked and the content isn't sitting in plain sight.
Use it whenever the file matters more than the message: signed NDAs, board packs, financial statements, ID scans requested by a landlord, or anything you'd rather not see forwarded around. Share the password through a different channel — text or a phone call, not the same email — otherwise the encryption is only slowing down a curious reader, not a determined one.
The tool uses standard PDF encryption. Security depends on your chosen password strength.
Currently, the tool sets a single password required to open the PDF.
No, any standard PDF reader can open password-protected PDFs.
To change the password, unlock with the current one, then re-protect with a new password.
Strip the password prompt off a PDF you already own — so you can copy text, print, or edit without typing it every time.
Stitch several PDFs into one file — cover letter + CV, or scanned pages that arrived one at a time.
Shrink a PDF that's too big to email or upload — usually by compressing the embedded images, not the text.
Lock your .doc or .docx layout into a PDF so the recipient sees the exact fonts, spacing and page breaks you wrote.
