Open/Extract 7z File with Freeware on Windows/Mac/Linux

7z is a compressed archive file format that supports several different data compression, encryption and pre-processing algorithms. The 7z format initially appeared as implemented by the 7-Zip archiver.

The 7z format provides the following main features:

  • Open, modular architecture which allows any compression, conversion, or encryption method to be stacked.
  • High compression ratios (depending on the compression method used)
  • Rijndael/AES-256 encryption.
  • Large file support (up to approximately 16 exbibytes).
  • Unicode file names
  • Support for solid compression, where multiple files of like type are compressed within a single stream, in order to exploit the combined redundancy inherent in similar files.
  • Compression and encryption of archive headers.
  • Support for multi-part archives : e.g. xxx.7z.001, xxx.7z.002, ... (see the context menu items Split File... to create them and Combine Files... to re-assemble an archive from a set of multi-part component files)

The format's open architecture allows additional future compression methods to be added to the standard.

While 7z compression uses the LZMA method by default, the 7z format also supports the PPMD, BCJ, BCJ2, BZip2, and Deflate compression methods.

The 7z format supports encryption with the AES algorithm with a 256-bit key. The key is generated from a user-supplied passphrase using an algorithm based on the SHA-256 hash function.
