verified_user Your files are processed only as needed and are not stored after the tool finishes.
Add a password to your PDF before sending contracts, forms, reports, invoices, or private documents. This free online PDF protection tool encrypts your uploaded PDF with the password you choose, then returns a new protected file that requires that password when opened in compatible PDF readers. The process is simple: upload one PDF, type a password of at least four characters, and download the encrypted result. Files are handled in memory by the backend and are not stored after processing. Use this tool when you need a quick extra layer of access control for shared documents, email attachments, or temporary file transfers.
