LZ4 Decompressor

This tool provides a focused decompression workflow for LZ4 blocks. It accepts hex, base64, or raw byte inputs and returns decompressed content when possible. Outputs can be UTF-8 text or base64 for binary payloads. It is designed for developers, data engineers, and QA teams debugging compressed data.
Conceptually, the tool decodes the input to a byte stream and applies the LZ4 block decompression algorithm: read the token, accumulate literals, read the offset and match length, copy matches from earlier data, and repeat until the block ends. It validates data integrity and reports precise error codes on malformed input.
Audience and value: it speeds debugging of data pipelines, verification of logs, and recovery of information from compressed messages. By avoiding a custom decoder, teams reduce risk and save time during triage and incident response.
Core features and use cases: input encoding flexibility, deterministic outcomes, optional output size capping, and export options. Typical use cases include inspecting a single block from a log line, validating transmission of compressed payloads, and extracting embedded text from binary records.
