Common questions
Can 7-Zip open RAR files created by WinRAR?
Yes. 7-Zip reads RAR versions 2 through 5 natively — no plugin, codec pack or extra download. If an archive fails to open, it is damaged rather than misread.
Which compression is smaller, 7z or RAR?
At maximum settings, 7z with the LZMA2 codec usually wins by 10-20%. In practice, with default settings, the difference is small enough that either choice produces a file people can open.
Is WinRAR safe to install?
It is a legitimate long-standing commercial product, but it is paid and has historically bundled a trial nagscreen. 7-Zip is free, open source and carries no installer ads at all.
