Binary to Text Converter

A binary to text converter turns binary code (groups of 0s and 1s) into readable characters, and turns text back into binary. Each character is stored as a number, and binary writes that number in base 2: the letter A is 65, written 01000001. This tool converts in both directions as you type and runs in your browser.

In Binary → Text mode, enter 8-bit groups (bytes) separated by spaces or line breaks, such as 01001000 01101001 for "Hi". Each group must be exactly eight 0s and 1s; if one isn't, the tool shows which group is invalid. In Text → Binary mode, each character becomes an 8-bit group, separated by spaces.

Limits: the converter maps one character to one byte, so it is reliable for standard ASCII (English letters, digits and punctuation). Most emoji and non-Latin characters produce groups longer than 8 bits that can't be decoded back, and binary made by a UTF-8 tool may decode accented letters incorrectly. It converts typed text, not .bin files.

Use it to decode a binary message in a puzzle, a homework exercise or a meme, to check a computer science exercise, or to see how text is stored as bytes. By hand you would convert every 8-bit group to a number and look it up in an ASCII table; the converter does both at once.
