info About this tool
Convert RAR archives to the 7Z (7-Zip) format. While both RAR and 7Z offer excellent compression, 7Z is completely open-source with no proprietary restrictions. 7Z typically achieves 2 to 10 percent better compression than RAR and is supported by 7-Zip on all platforms. This conversion is useful when you want to repackage RAR archives in a format that is both more compressible and free from licensing constraints.

File size: 7Z archives are often 5 to 10 percent smaller than equivalent RAR archives using LZMA2 compression.

Quality: Files are extracted and repackaged. Contents are not modified.
