7Z vs LZMA
Un confronto dettagliato tra 7-Zip Archive e LZMA Compressed: dimensioni del file, qualità, compatibilità e quale formato scegliere per il tuo flusso di lavoro.
7-Zip Archive
Archives & Compressed7z uses the LZMA2 compression algorithm to achieve significantly better compression ratios than ZIP. It is open-source and supports strong AES-256 encryption.
Informazioni sui file 7ZLZMA Compressed
Archives & CompressedLZMA (Lempel-Ziv-Markov chain Algorithm) is a high-ratio compression algorithm developed by Igor Pavlov for the 7-Zip archiver. It achieves significantly better compression than gzip or bzip2, especially on text and binary data, at the cost of higher memory usage.
Informazioni sui file LZMAConfronto dei punti di forza
7Z Punti di forza
- Outstanding compression ratio — typically 20–50% smaller than ZIP, 10–30% smaller than RAR.
- Completely free and open source.
- AES-256 encryption of both content and filenames.
- Supports enormous archives (16 exabytes).
- Multi-threaded compression on modern CPUs.
LZMA Punti di forza
- Highest-ratio mainstream compression (beats gzip by 30%).
- Public domain SDK — royalty-free.
- Mature since 1998 with no breaking changes.
- Core of 7z, xz, .tar.xz workflows.
- Multi-threaded LZMA2 scales across CPU cores.
Limitazioni
7Z Limitazioni
- Not natively supported on Windows before Windows 11 23H2 or macOS — requires a separate tool.
- Slower compression than ZIP (though decompression is fast).
- No built-in recovery records like RAR.
- Less ubiquitous in email and casual sharing than ZIP.
LZMA Limitazioni
- Slow compression at highest settings.
- Memory-hungry — 1 GB+ for extreme compression levels.
- Zstandard matches its ratios at less memory cost.
- Raw .lzma files are rare — usually wrapped in .7z, .xz, or .tar.xz.

Dimensioni tipiche dei file
7Z
- Source code archive ~50% smaller than ZIP
- Linux distro installer 2–10 GB
- Virtual machine disk image 5–40 GB
LZMA
- Text/source archive 15-25% of original
- Linux kernel source (.tar.xz = LZMA2) ~125 MB
- Windows system backup (.lzma) 25-40% of original
