An easy to use ActiveX/COM data compression library built for the x86-64 architecture. You name the feature, it does it. Zip, unzip, updating, converting, disk and memory streaming, AES encryption, no 4GB or file limit, various compression algorithms, filtering, split/spanned/self-extracting zip files, and much more.

Technically superior

The library is a fully self-contained DLL, written with ATL 3.0 and with no external dependencies, STA/MTA multi-threaded apartment models, Unicode file and I/O calls, and more. Use it as an ActiveX/COM control, or access it as a standard 64-bit DLL through its exported API.

Advanced capabilities include non-blocking methods for background operation, wildcards that work even for folder names, renaming files in a zip file without unzipping then rezipping, etc.


Updated and improved for over 20 years, used in applications everywhere, you can trust it to create robust applications that execute error-free with any kind of input data.

Features :

  • Built for the x86-64 processor architecture. A version for the IA-64 processor architecture is also available on request.

  • A single fully self-contained COM object and ActiveX control written with ATL 3.0.

  • Requires no external compression DLLs, MFC DLLs, or other runtime libraries.

  • Both single-threaded (STA) and multi-threaded apartment (MTA) model design.

  • Instantiate the component dynamically without putting it on a form.

  • Supports multiple instances running simultaneously.

  • Supports both Unicode and ANSI in one single control. The library automatically uses Unicode API calls for best performance where available.

  • ActiveX control interface has all constants, enumerations, and types built-in. Code completion, property categories, help strings, and context-sensitive F1-help fully supported.

  • Works with all 32-bit development environments that can use ActiveX controls, including VB, VC++, Delphi, C++ Builder, VFP, Office, PB, VO, Web scripting languages, ASP, and DCOM projects.

  • Also compatible with VB.NET and C#. For developers that require 100% managed code, check out Xceed Zip for .NET, our fully object-oriented Zip, compression and FileSystem class library.

  • Supports WinZip 9.0 (and up) compatible AES strong encryption.

  • Fast, low memory usage compression engine.

  • 100% compatible with the PKZIP 2.04g format.

  • 100% compatible with the PKZIP 4.5 format.

  • Supports the Zip64 zip file format allowing the creation of Zip files of practically unlimited size (no 4 GB limit).

  • Supports the BZip2 (BWT) compression method for 15% to 20% better compression than Deflate on many popular file types, especially XML data.

  • The only library to provide WinZip 12 compatibility, supporting the LZMA algorithm for improved compression in certain situations. Note: Zip files using WinZip 12’s special JPEG recompression feature are not supported.

  • UTF-8 character encoding in headers for improved support of international characters in filenames and comments is provided.

  • Supports the Deflate64TM compression method, an industry standard improvement to regular Deflate.

  • Zip files can contain any number of files (no 65535 file limit).

  • Regular, spanned, and self-extracting zip files created by Xceed Zip can be used by any of today’s existing unzipping applications, and vice-versa.

  • Stores and retrieves the latest zip file format extensions, allowing Unicode filenames and NT file attributes, extra time stamps, and security permissions to be stored in the zip file.

  • No need to repair corrupted zip files. Xceed Zip automatically tries to recover from errors and reports any inconsistencies found in the zip file while unzipping.

  • Zip files or memory buffers into new or existing zip files.

  • Unzip files to disk or directly to memory.

  • Compress and decompress strings or buffers completely in memory.

  • Your application receives info such as a file’s achieved compression ratio, compressed size, and other info as it becomes available.

  • Informs your application that it should prompt the user to insert a specific disk when reading or writing zip files that span multiple disks.
