If you are looking for PKZIP, you have come to the right place. We explain what PKZIP is and point you to the official download.

What is PKZIP?

PKZIP is a compression and encryption solution available for several operating systems. There is an edition for z/OS, one for the i5/iOS, one for Linux, one for DOS, and one for Windows. There is a server edition of the utility as well.

The compression capabilities of PKZIP are notably powerful: some files can be compressed by up to 95%, rendering them far easier to transfer across storage media or multiple devices. Despite the small file sizes it achieves after compression, there is zero data loss since the software uses lossless compression techniques. It also supports encryption and compression of even enormous files. For instance, files passing 9 exabytes can still be compressed by the software, and folders with millions of files (the actual limit is 2B) can be compressed in a single archive.

Encryption on PKZIP is of the 3DES and AES types, and renders even filenames invisible until the archive is decrypted. It is also capable of integrating with Outlook for automated mail encryption (although this is optional).

The program can create archives in nearly all the archive file types currently in use, from ZIP to XXEncode.
