In order to achieve compression rates of up to 50% better than standard .ZIP, 7-Zip uses the new .7z compression format, which gets amazing results without any loss in quality or speed. File size is all we are going to lose!

Going a bit deeper into technical aspects I can tell you that the program uses the new 7z file format by default. This format uses LZMA (Lempel-Ziv-Markov algorithm) compression method which is more suitable for texts, it was developed by its author, and can apply a filter to the executable to increase their compressibility. 7z files can be solid, unlike the ZIP, thus improving the compression of sets of small files.

Along with this new format, 7-Zip brings extensive support for multiple formats including common ones like .ZIP, .CAB, .RAR, .ARJ, .GZIP, .TAR and many, many others. So we can get excellent results with almost any archive we may come across in our daily work.

7 Zip Compression Options

Note: With 7-Zip we can extract and compress 7z, ZIP, GZIP, BZIP2 and TAR formats but only extract ARJ, CAB, CHM, CPIO, DEB, DMG, HFS, ISO, LZH, LZMA, MSI, NSIS, RAR, RPM, UDF, WIM, XAR and Z.
