About the formats
RAR archive
RAR is a proprietary archive format known for strong compression and reliable recovery records. It is easy to open everywhere but can only be created with WinRAR, so it is best converted to ZIP or 7z for sharing.
Strengths
- Strong compression
- Recovery records resist corruption
- Splits neatly into multi-part volumes
Limitations
- Proprietary — needs WinRAR to create
- Not freely redistributable
- Less universal than ZIP
Best for: Opening RAR downloads — converted to ZIP or 7z so anyone can extract them freely.
7z archive
7z is the native format of 7-Zip, using LZMA compression to squeeze files far smaller than ZIP. It supports strong AES-256 encryption and solid archives, at the cost of needing 7-Zip-compatible software.
Strengths
- Excellent compression ratio
- Strong AES-256 encryption
- Handles very large archives
Limitations
- Needs 7-Zip-compatible software to open
- Slower to compress
- Less universal than ZIP
Best for: Packing large collections as tightly as possible when recipients can use 7-Zip.
