About Document Password Protector
Some documents simply aren't meant for every set of eyes. Contracts, financial records, and personal letters can carry information that should stay private even after you send the file along. Adding a password is the simplest way to keep a Word document locked to the people you trust. This tool applies password protection to your DOCX quickly.
Upload your .docx, set a password, and download the protected document. Everything happens in your browser through ToolHub by Codaiman, so there's no account, no installed software, and no watermark, and your file stays on your side. The tool is free, and it gives you an extra layer of security so only those with the password can open the file.

FAQ
What happens if I forget the password?

Will the password be required every time?
Yes. Anyone opening the protected document, including you, will need to enter the password to view its contents.
Does it work in Microsoft Word?
Yes. The protected file uses standard DOCX password protection, so Word and compatible editors will prompt for the password.
