Binary Run-Length Encoder & Decoder
Encode bit strings as explicit JSON runs or decode validated runs with allocation limits and per-run inspection.
Ready. Explore the example or use the input controls to begin.
Scope and practical limits
Encode/decode up to 50,000 bits. Source text up to 50,000 characters. Run schema is {bit:"0" or "1",count:positive integer}. This is a demonstration JSON format, not a standard compressed-file codec.

Using Binary Run-Length Encoder & Decoder
Encode bit strings as explicit JSON runs or decode validated runs with allocation limits and per-run inspection.
- Start with the example and choose the declared input representation and any bit width.
- Change the operation or format, then inspect the precise result and validation messages.
- Copy the output or download text, JSON or a CSV audit. Save a project to retain editable inputs.
Example
00011 becomes [{"bit":"0","count":3},{"bit":"1","count":2}]. Counts are validated before expansion.Questions & answers
