Binary to Text Converter

This tool converts text into binary and binary back into text, revealing the ones and zeros that computers actually use to store every character. At the lowest level, computers represent everything as binary, sequences of bits that are either 0 or 1. Each character you type, a letter, digit, space or symbol, is stored as a number according to a character encoding, and that number is written in binary as a group of bits, usually eight, called a byte. Converting between readable text and its binary form is a classic exercise for learning how computers work, a handy tool for programming and debugging, and a bit of fun for puzzles and secret messages. This converter does both directions. You paste your text to turn it into binary, where each character becomes its eight-bit code with the bytes separated by spaces, or you paste binary, groups of eight bits, to turn it back into readable text. The tool detects which way you want to go from the mode you choose and converts instantly. It works through UTF-8, the standard modern encoding, so ordinary English characters become single bytes while accented letters, macrons and emoji become several bytes, and all of them convert correctly in both directions. Everything runs in your browser, so nothing is uploaded. Use it to learn how text is encoded, to convert a message to or from binary for a puzzle or lesson, or for programming and debugging. The eight-bit grouping reflects how a byte stores one basic character: for example, the capital letter H is 01001000 in binary. Seeing text laid out as binary makes the link between the characters we read and the numbers a computer stores tangible and clear.

Each character becomes its 8-bit code via UTF-8, bytes separated by spaces. Accented characters and emoji use several bytes. Runs entirely in your browser.
