7Zip vs PeaZip

To free up storage memory, we compress large files. Although Windows OS has a file compressor tool built-in, the size of archives generated by the tool will be smaller than that created by third-party software. You’ll find many file compression software on the internet. Some applications employ their own algorithm to create compressed archives, and others give you to option to choose the algorithm or format in which you would like the software to create the archive.

Peazip and 7Zip are two widely used file compression software. 7-Zip was introduced in 1999, and PeaZip was launched in 2006. Both the software are powerful and widely used.

Which software supports more formats and has more features? Below, we’ve compared the two file archiver/decompressor software.

7Zip interface looks a bit outdated but is easy to use. The software boasts these options on its toolbar – add, extract, test, copy, move, delete, info. PeaZip’s interface looks better than that of 7Zip. On its toolbar, you’ll find five buttons – add, convert, extract, test, and secure delete. What do these buttons do?

You can see the contents of folders by double-clicking them or see the details of the files/folders by right-clicking the file and choosing the “properties” option. PeaZip and 7-Zip software show the size of the files and make users aware of the number of files present in the folder.


You can configure 7-Zip & PeaZip to use N number of CPU threads while compressing the file. File compression is a CPU-intensive task. You can make 7-Zip use a certain amount of RAM while archiving files.
