ZIP vs RAR: universal support or stronger compression?
A clear, practical comparison with a straight answer.
Use ZIP when the recipient needs to open the archive without installing anything. Use RAR when you already have WinRAR and want tighter compression or recovery records for a large or important archive.
ZIP is built into every major operating system, so anyone can open one without installing anything. RAR usually compresses tighter and can add recovery data that repairs a damaged archive, but only WinRAR's paid tools can create one.
Extraction is free either way; free tools open both formats on every platform. The real decision is whether you are willing to trade universal, no-install compatibility for RAR's extra compression and repair features.

Frequently asked questions
Can I create a RAR file for free?
Not with official tools, creating RAR requires WinRAR, which is paid after its trial. ZIP and 7Z are free to both create and extract.
Why do downloads sometimes come as RAR instead of ZIP?
RAR often compresses better and can split large downloads into parts with recovery data, which some distributors prefer for big files.
