Is my text uploaded to a server?

No. All encoding and decoding runs locally in your browser using JavaScript. Nothing is sent anywhere.

Does this support Unicode / emoji?

Yes. Characters with code points above 127 are encoded as their UTF-8 byte sequences. Each byte of the multi-byte sequence is shown separately in binary or hex.

What format should binary input be in for decoding?

Enter 8-digit groups separated by spaces — e.g. 01001000 01101001. The decoder also accepts binary without spaces as long as the total length is a multiple of 8.

What format should hex input be in for decoding?

Enter 2-character hex pairs separated by spaces — e.g. 48 69. The decoder also accepts hex without spaces (e.g. 4869) and handles both uppercase and lowercase letters.

How Text → Binary Works

Every character in a string has a numeric code point (its Unicode / ASCII value). Binary encoding converts each character to its 8-bit binary representation. For example, the letter A has the ASCII value 65, which in binary is 01000001. Bytes are typically separated by spaces for readability.

Encoding Reference

Character	Decimal	Binary	Hex
A	65	01000001	41
a	97	01100001	61
0	48	00110000	30
Space	32	00100000	20
!	33	00100001	21

Binary vs Hex

Binary (base 2) uses only 0s and 1s — each character expands to 8 digits, making output verbose but easy to understand bit-by-bit. Hexadecimal (base 16) uses digits 0–9 and letters A–F — each character becomes just 2 hex digits, making it far more compact. Hex is the standard in programming, colour codes, and byte-level debugging.
