About PDFEncrypt
PDFEncrypt is a free, open source utility to encrypt PDF files using standard PDF encryption algorithms. When a document is encrypted, its contents become unreadable. An authorized user can decrypt the document to obtain access to the contents. If a PDF document is encrypted with a password, the user must specify the password before the document can be viewed in Adobe Reader or Adobe Acrobat. PDFEncrypt provides a means to encrypt any standard PDF document for free, without the need to purchase the Adobe Acrobat software or upload your confidential PDF files to a third-party server for encryption. The app runs directly on your Windows PC and allows you to specify a password (required to open the document) as well as many options and permissions to apply to the PDF file.
