PDF Password Protect
Add password protection to a PDF directly in your browser for safer sharing, client handoff, internal documents, invoices, proposals, and private downloads.
How it works
Password protect PDF files online for safer sharing, client handoff, and private downloads
This free PDF password protection tool helps you lock a document before sharing it by email, private link, cloud upload, or direct download. It is useful for proposals, invoices, contracts, client-ready files, internal notes, portfolios, and personal records that should not open without a password.
Upload your PDF, enter a password, preview the first page, and generate a password-protected PDF directly in your browser. This keeps the workflow simple when you need to secure a file without opening a heavier desktop PDF editor.
