Frequently Asked Questions

What format input?

Space- or comma-separated 8-bit groups (01000001 01000010). Malformed groups error with exact positions instead of guessing.

Non-8-bit groups?

7-bit ASCII and 16-bit units decode where unambiguous; mixed widths need explicit mode selection. Default assumes UTF-8 bytes.

Who uses this?

Students verifying encoding homework, engineers reading protocol dumps, and CTF players decoding challenges.

Is input uploaded?

No — decoding runs locally in your browser. Nothing leaves your device.
