LZMA vs TAR
Una comparativa detallada de LZMA Compressed y TAR Archive — tamaño de archivo, calidad, compatibilidad y cuál elegir según tu flujo de trabajo.
LZMA 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.
Sobre los archivos LZMATAR Archive
Archives & CompressedTAR is a Unix archive format that bundles files together without compression. It is commonly combined with gzip or bzip2 for compressed archives and is the standard for Linux software distribution.
Sobre los archivos TARComparativa de ventajas
LZMA Ventajas
- 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.
TAR Ventajas
- Streamable — you can tar files straight to a network pipe, no seek needed.
- Preserves Unix permissions, ownership, symbolic links, and timestamps.
- Universally supported on Unix-like systems.
- Simple format — the GNU tar source has been stable for decades.
- No compression overhead — pair with gzip/xz/zstd as needed.
Limitaciones
LZMA Limitaciones
- 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.
TAR Limitaciones
- No built-in compression — plain .tar files are the same size as their contents.
- No random access — reading one file requires scanning from the start.
- Windows tooling is second-class — PowerShell only added native tar in 2018.
- Multiple incompatible header variants (v7, ustar, POSIX, GNU) over the years.

Tamaños típicos de archivo
LZMA
- Text/source archive 15-25% of original
- Linux kernel source (.tar.xz = LZMA2) ~125 MB
- Windows system backup (.lzma) 25-40% of original
TAR
- 1 MB of source files (uncompressed .tar) ~1 MB
- Same files as .tar.gz 150-400 KB
- Linux kernel source (.tar.xz) ~120 MB

Preguntas frecuentes
LZMA (LZMA Compressed) is an archive format used to bundle multiple files and folders into a single compressed file. The archive preserves the directory structure and typically reduces total size via compression. LZMA sits in the archives & compressed family and has specific strengths around compression ratio, speed, or platform support.
LZMA (LZMA comprimido) is an archive formato used to bundle multiple arquivos e folders em a single comprimido file. The archive preserves the directory structure e tipicamente reduces total size via compressão. LZMA sits no archives & comprimido family e has specific strengths around compressão ratio, speed, ou plataforma support.
7-Zip, WinRAR, The Unarchiver (macOS), and the built-in archive utilities on Windows and macOS open most LZMA files. For command-line extraction, 7z, unar, or the format-specific tool handles LZMA cleanly. If your extractor does not recognise LZMA, convert to ZIP first — ZIP opens on every operating system without extra software.

Upload the LZMA to KaijuConverter and pick ZIP, 7Z, TAR.GZ, or RAR as the target. Our pipeline extracts the original archive and re-compresses the contents into the target format. File permissions, timestamps, and directory structure are preserved where both formats support them.
Depends on the goal. ZIP is the universal baseline — every OS extracts it out of the box. Formats like 7Z or TAR.GZ compress better but require specific tools. LZMA may win on compression ratio, password support, or OS integration for specific workflows; ZIP wins on raw compatibility.
