Protect your files from unauthorized access by applying banking-level security with 128- or 256-bit AES encryption. For extra security, set your own password policy by defining complexity requirements that WinZip will enforce for you.
NEW! Add watermarks
Deter unauthorized copying, add traceability and protect your intellectual property by adding custom watermarks to images and PDFs. You control the transparency of your watermark, and choose how and where it appears. Add a date/time stamp to your watermark for even more security.
