7-Zip v18.05 Portable

You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip. But you can make a donation to support further development of 7-Zip.

The main features of 7-Zip

High compression ratio in 7z format with LZMA and LZMA2 compression

Supported formats:

  Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM

  Unpacking only: ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR and Z.

For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip

Strong AES-256 encryption in 7z and ZIP formats

Self-extracting capability for 7z format

Integration with Windows Shell

Powerful File Manager

Powerful command line version

Plugin for FAR Manager

Localizations for 79 languages

7z is the new archive format, providing high compression ratio.

The main features of 7z format:

    * Open architecture

    * High compression ratio

    * Strong AES-256 encryption

    * Ability of using any compression, conversion or encryption method

    * Supporting files with sizes up to 16000000000 GB

    * Unicode file names

    * Solid compressing

    * Archive headers compressing 

LZMA compression algorithm is very suitable for embedded applications. LZMA is released under the terms of the GNU LGPL. LZMA is also available under a proprietary license for those who can not use the GNU LGPL in their code. If you want to use LZMA code, you can ask consultations, custom code programming and required developer licenses from page for support: Send message to LZMA developer. Check also information about LZMA SDK.

7-Zip also supports encryption with AES-256 algorithm. This algorithm uses cipher key with length of 256 bits. To create that key 7-Zip uses derivation function based on SHA-256 hash algorithm. A key derivation function produces a derived key from text password defined by user. For increasing the cost of exhaustive search for passwords 7-Zip uses big number of iterations to produce cipher key from text password.
