DOCX (Microsoft Word Document) is a text file created by Microsoft Word or exported by another desktop or online office application like Google Docs. DOCX files usually contain textual information, tables, images, and charts. This format is widely supported and used because of its rich formatting features and the open structure that is described in the Office Open XML file format specification. When the DOCX file is not protected anyone who can access your file can open it. In case your DOCX document contains sensitive or private information you can limit access to your file by setting a password.

Password Protect is a free secure online web application that enables you to protect DOCX documents. You can easily add a password to DOCX document within a couple of clicks and download a protected file.

To password protect DOCX documents we're using ECMA-376 Standard Encryption (AES128 + SHA1). This encryption method provides high protection level against brute-force attacks that are used by attackers to decrypt a protected file.

To secure DOCX document using Password Protect application upload your file, type the password, click protect button, and download the protected file. The download link will be available for 24 hours. While we automatically remove your files from our servers we also enable you to remove the files manually. After you removed files manually the download link won’t work anymore.
