RLE Converter

About This Tool

The rle converter provides a bidirectional, code-free way to experiment with run-length encoding. It accepts a text input and a mode toggle (encode or decode), returning a deterministic result suitable for code testing, teaching, or quick data scenarios. The encoding process compresses consecutive identical characters into a count and the character, while decoding expands those counts back to original text. This tool supports Unicode input, making it usable across languages and data sets. It is particularly valuable for developers validating a codec, educators illustrating compression basics, and analysts benchmarking simple schemes against more complex algorithms. The core value lies in immediacy, transparency of the algorithm, and the ability to produce and compare both directions in a single interface. Use cases include preparing teaching examples, generating synthetic data with known run lengths, and verifying that a decoder correctly reconstructs the original string from a given encoded form. The tool emphasizes correctness and clarity over speculative optimizations, enabling clear traceability of each step in the encoding or decoding process.
