텍스트 to Binary

What is 텍스트 to Binary?

A text-to-binary converter encodes each character of input text into its 8-bit binary representation (a string of 0s and 1s). Computers store all data as binary; this tool makes that representation visible, which is useful for learning how text is encoded, debugging low-level protocols, and creating binary art. The decoder reverses the process, parsing groups of 8 bits back into characters.

How It Works

Encoding uses TextEncoder to convert the input string into UTF-8 bytes, then each byte is rendered as an 8-character binary string via toString(2) padded with leading zeros. The bits are typically space-separated for readability. Decoding splits the binary string on whitespace, parses each 8-bit group as a base-2 integer, collects the bytes, and decodes them back to a UTF-8 string via TextDecoder. Multi-byte UTF-8 characters (emoji, CJK) produce multiple bytes.

Common Use Cases

• Learning how text is stored — see the binary representation of ASCII and UTF-8 characters
• Debugging low-level protocols — inspect the exact bytes a string produces
• Creating binary puzzles or art — convert a message into bits for a challenge
• Verifying encoding correctness — confirm a string's byte sequence matches expectations

Technical Details

Encoding: UTF-8 via TextEncoder (variable-width: ASCII = 1 byte, emoji = 4 bytes). Each byte → 8 binary digits (toString(2) padded to 8). Output is space-separated 8-bit groups. Decoding parses base-2 groups and uses TextDecoder for UTF-8. ASCII characters (0-127) produce a single byte; multi-byte characters produce proportionally more bits. The tool is bidirectional and lossless for valid UTF-8.
