PKZIP for Windows Desktop

File Compression Software

PKZIP continues to be the gold standard in data compression and file management, evolving as your needs have changed. PKZIP compresses and extracts files to greatly reduce required storage space and transmission times. And, by using the .ZIP standard, the most widely used file standard in the world, you can easily exchange data across all major computing platforms more efficiently and effectively.

Built on the familiar and reliable .ZIP standard, SecureZIP is the only data-centric security product that allows you to encrypt information on one computing platform and transfer it to any other computing platform in your environment. Learn more about SecureZIP
