7-Zip Portable is an excellent freeware file compression/decompression tool which supports most popular file compression formats including ZIP, 7Z, RAR, CAB, ISO and GZIP.
Since this application is portable, it can be used without having to install the program. This can be suitable for usage on various portable mass storage devices like USB thumb drives, external hard drives or even on your phone.
The main interface of 7-Zip Portable is identical to 7-Zip which can be described as easy-to-use and get around in. It's not very different from older legacy programs like WinZip or WinRAR except for the fact that there are no nags screens being a freeware program.
In terms of file support, 7-Zip Portable can handle most of the archives you may come across online. Naturally, it also supports its native format of 7Z. It can decompress more than it can compress, but there aren't any issues creating ZIP or 7Z files which are standard anyways.
Overall, it's good that there's a portable version of this program available as it's definitely one of the best file archivers out there.7-Zip Portable features and highlights:
