FAQ
Does it work with Korean?+
Yes — UTF-8 encoding handles Korean too (one character = 3 bytes = 24 bits).
Why is 'A' 01000001?+
ASCII defines 'A' = 65 = 01000001 in binary. Computers store every character as a number, and the number is a binary pattern of 0s and 1s.
Do I need to separate bits with spaces?+
The tool auto-detects them. You can group by 8 bits or input without spaces.
What about non-ASCII characters?+
Korean, Japanese, and emojis use UTF-8 variable-length encoding (1–4 bytes). The tool handles it automatically.
Can I use this to make a cipher?+
No — plain binary representation isn't encryption. Anyone can decode it. Real cryptography uses AES or RSA.
