- Configure any options as needed.
- View the results instantly and copy or download the output.
Tips & Best Practices
- Encoding is byte-level UTF-8: a 1-character emoji like 😀 emits 4 bytes (32 bits in binary mode), not 1.
- Decoding expects byte values 0–255. Anything outside that range raises an error.
- Use the swap button to flip between text→binary and binary→text without retyping.
- Binary mode pads each byte to 8 bits; hex pads to 2 digits; octal to 3.
- Runs entirely in your browser; pasted text never leaves your machine.
