Text to Binary Converter
Convert plain text to binary code (0s and 1s) and binary back to text. Shows ASCII values for each character. Free.
How to use the Text ↔ Binary
How text becomes binary
Every character has an ASCII code (a number 0–127). That number is then represented in binary (base 2). "A" has ASCII code 65, which in binary is 01000001. "a" is 97 → 01100001. Numbers and symbols each have their own ASCII codes too.
Decoding binary text
Switch to "Binary → Text" to decode binary back to readable text. Paste binary with spaces between each 8-bit group (or no separators — the tool handles both). Binary messages of exactly 8 bits per character can always be decoded.
