ZIP archives that reduce file size by as much as 95 percent
Conserve storage space on hard drives and portable devices.
ZIP compression from the creator of the ZIP format
PKWARE is the original developer of the ZIP compression format. Since its inception, PKWARE has made ZIP specifications freely available to the public as a standard for compressed data storage. Consequently, ZIP is one of the most widely used file formats in the world. PKWARE is continually reinvesting in added functionality for PKZIP brand products, making it the unquestioned leader in the industry.
Very large archive support
Over 2 billion files can be included in a ZIP archive.
Helpful web, email, and telephone support
PKWARE's experienced technical support staff offers live telephone support* in addition to web and email support should any issues ever arise.
Strong password-based data file protection
PKZIP supports AES or 3DES encryption using passphrases or passwords to protect valuable information. Files encrypted with PKZIP may be decrypted and extracted on major enterprise computing platforms using PKZIP or SecureZIP.
Decryption of PKI public key encrypted ZIP archives
PKZIP users can decrypt and extract files encrypted with a PKI public key by SecureZIP products.
Authentication of digitally signed archives and files
Recipients of digitally signed files can validate the signature to ensure the sender is who he or she claims to be, and verify that files have not been altered or tampered with since it was signed.
Cross-platform data portability
ZIP archives are portable data containers that can be read and decompressed on many operating systems. PKWARE is the only single-source vendor of ZIP compression products across the major enterprise operating systems - interoperability is guaranteed
Command-line add-on for automating recurring tasks
PKZIP provides a command-line interface allowing users to create scripts for automating unattended script and batch processing.
Configurable Minimum Passphrase Length
Good passphrases are essential to maintaining the security of your data - the longer the passphrase, the more secure it is. PKZIP allows administrators to configure the minimum length of passphrases created by users.
Certificate Revocation List Checking
PKZIP can check the validity of digital certificates used to encrypt or digitally sign files against a Certificate Revocation List (CRL). When a PKZIP user receives a file that was signed or encrypted using SecureZIP, CRL checking will show a certificate that has been revoked as invalid.

What is the difference between PKZIP for Windows Standard Edition and Enterprise Edition?
PKZIP for Windows Enterprise Edition adds centralized administrative control of end-user options from the Microsoft Management Console to ensure consistent compression and file protection on all user desktops.
What is the difference between SecureZIP and PKZIP?
PKZIP, the original ZIP compression program, has long been the leading zip compression product. Phil Katz (the "PK" of PKWARE and PKZIP) developed the ZIP format in the late 1980's to address problems arising from handling large files in an era of slow PC's and modest bandwidth. ZIP provided a container that streamlined the transfer of files across operating systems. The first PKZIP was developed for the DOS command line. Later versions were developed for UNIX command line, and eventually ZIP proliferated until today when PKZIP data compression is available for all major enterprise operating systems, including Windows desktop and server, UNIX server, Linux server, AS/400, and IBM mainframe. Moreover, a ZIP file created by one PKZIP product on one operating system can be read by any other PKZIP product on any other supported operating system. PKZIP applications are the best cross-platform-compatible tools for the efficient use of storage and network bandwidth for transferring data.
While PKZIP has, for almost two decades, focused on the efficient storage and transfer of data across platforms, SecureZIP extends those virtues by including several significant data file security benefits. All PKZIP features and functions are included within SecureZIP, which adds strong encryption, either passphrase-based or public key-enabled (PKE), and digital signing/authentication, to the classic ZIP compression process. These features provide customers with the confidence that their data is persistently protected with a level of diligence to meet the expectations of internal data security professionals, external IT auditors, and the organization's critical stakeholders and stockholders. Even more important, these data protection virtues apply even when the protected data is transferred from one supported operating system to another. The SecureZIP applications are the best cross-platform compatible tools for protecting sensitive personal and corporate data, such as company trade secrets, confidential intellectual property, financial records, and private health information (PHI). Further, data encrypted with SecureZIP is strongly protected, at rest and in transit, regardless of the destination storage device or the transport protocol, inside and outside the office perimeter.
Why choose PKZIP over WinZip?
PKWARE created the original ZIP file format for storing and transporting compressed data files, PKZIP. The company remains the technology leader in this market, and continues to add features and functionality to this popular file format. Other zip vendors, including WinZip, look to PKWARE for leadership in identifying market needs and identifying how ZIP technology can be modified or extended to meet these needs Because PKZIP introduces new functionality before other zip applications, customers can be assured that PKZIP will offer the latest innovations that enhance its utility.
Not only is PKWARE the technology leader, but it is also the ONLY provider of cross-platform interoperable zip applications. This provides further assurances that a zipped file can be opened by it's intended recipient, regardless of the recipient's computer platform. Zipping files provides a number of benefits, including reducing the space required to store files on a hard drive, backup disk, or USB or other portable storage media. In addition, smaller attachments are less likely to be blocked by email filters, streamlining file transfer for parents, students, and small business people.
Data security is a primary concern for many computer users, and PKZIP provides industry standard encryption technology, which ensures that only the intended recipient(s) can open the protected file. PKZIP's strong password-based encryption uses the RSA® BSAFE® cryptographic libraries and supports both AES and 3DES encryption - advanced encryption standards accepted by industry and government as suitable for protecting sensitive information. WinZip, on the other hand, implemented its AES password-based encryption using an unsupported open-source algorithm. To keep data truly safe, encrypting the content of the files is not enough - PKZIP includes an option, File Name Encryption, which further frustrates hackers by protecting the names, dates, sizes of files and other attributes of the data you want to protect. Because WinZip does not provide filename encryption, anyone can see the contents of a zip archive including file names, file modification dates, and other sensitive information that can give a malicious person clues to the content of those files.
