Convert binary (base-2) sequences into readable text, or encode text into 8-bit binary. Binary representation shows up in low-level tutorials, encoding puzzles, embedded work and anywhere you need to see the exact bits behind a character. This converter groups your input into bytes, decodes them as UTF-8 so multi-byte characters come through correctly, and tolerates spaces between bytes for readability. Encoding works the other way, turning each character into its byte pattern separated by spaces. Choose a direction, paste your input, and copy the result. All processing happens locally in your browser, so whatever data you convert stays entirely on your device and is never sent to any server or third party.
