LZ4 Converter

About This Tool

The LZ4 Converter operates entirely in the browser to enable fast, lossless compression and decompression of data using the LZ4 algorithm. It accepts either plain text or base64-encoded input and outputs base64-encoded results by default, making it suitable for text-based transport and quick validation workflows. Conceptually, the tool implements a block-based encoder/decoder that scans input, identifies repeated sequences, emits literals, and encodes matches as length/distance pairs; decompression reverses this process deterministically. The primary beneficiaries are developers, data engineers, QA teams, and researchers who need to benchmark compression performance, validate data round-trips, or prototype integration with data pipelines without installing software. Its key value lies in in-browser execution, lightweight memory usage, and consistent results across runs. Core features include the ability to compress or decompress, base64 I/O, and clear error signaling for invalid input. Optional capabilities cover framing selection and chunked processing for large payloads, enabling more realistic testing in local environments. Practical use cases include assessing how JSON payloads compress under LZ4, validating end-to-end round trips in test suites, and benchmarking throughput in CI pipelines.
