Compressed to 25.6% of original74.4% saved

A container-free lz4 stream: decompress it to recover sample.txt. The bytes are the compressed data, so there is no inline content preview.

Testing contract

Expected to pass

Scenario: Exercise LZ4: Single File in its compression workflow. A text file compressed with the LZ4 frame format (.lz4), the container-free codec on its own, for testing LZ4 decompression and codec detection.
Expected result: Decompressed bytes=960; decompressed SHA-256=0439157c5c66cce4cd76e0974403918d3e3d5811ff1717beca392f9e78b1d368. Declared feature checks: codec=lz4; originalName=sample.txt; originalBytes=960; level=9.

What is a .lz4 file?

LZ4 (.lz4) is an extremely fast lossless compressor optimized for speed over ratio, common in databases, filesystems, and real-time pipelines where decompression throughput matters most.

How to use this file

Use an example .lz4 file to test LZ4 decompressors, frame-format parsing, and speed-versus-ratio comparisons.

How to use this file for testing

“LZ4: Single File” is a deterministic Testaroo fixture for Compression testing, Conversion testing. The same source saved at quality 10/50/90 for comparing compression artefacts and quality settings.

Documented properties for this file: LZ4 frame (single file). Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.

Archive fixtures are documented down to their member list (shown on this page) and are deliberately safe, no zip bombs, executables, or hidden payloads. Test extractors against nested, unicode, empty, and encrypted variants.
