What is a .LZO file?
LZO is a compression format built for very fast decompression.
- Did you know
- LZO favours speed, making it popular for real-time compression.
- LZO was written by Markus Oberhumer and is tuned so heavily for speed that decompression needs no extra memory at all.
- A modified version of LZO travelled to Mars aboard NASA rovers including Curiosity to compress data as it was collected.
- What Analyser reads
- Open more archives, packages and installers: macOS XAR/.pkg/.mpkg installers (member list), Windows .msu updates (CAB), Snap SquashFS packages, Flatpak bundles, StuffIt (.sit/.sitx), lzop (.lzo) and Brotli (.br) streams, Java Web Start (.jnlp), and the .tlz/.tbz/.tz compressed-tarball shorthands.
- Depth of analysis
- .LZO is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .LZO file
- Drag a .LZO file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
