Convert text to binary code. Fast, secure, and completely free. All processing happens in your browser — no data is sent to any server.
Text to Binary conversion represents each character of your input as its 8-bit binary equivalent, based on its underlying character encoding (typically UTF-8 for anything beyond basic ASCII). The letter 'A', for example, becomes 01000001 — its ASCII value 65 written in base 2. This is a foundational way to see exactly how text is represented at the byte level, which is useful for learning how character encoding works, or for producing binary-formatted output for a specific protocol, puzzle, or teaching exercise.
Understanding that text is fundamentally just numbers stored in binary is one of those concepts that clicks faster by seeing it directly than by reading about it — this tool makes that concrete for teaching or learning purposes. It's also genuinely useful for niche technical needs: constructing test vectors for a low-level protocol, working through a programming puzzle that expects binary input, or verifying how a specific character encodes at the byte level when debugging an encoding mismatch.
A single byte (8 bits) is the standard unit for representing one ASCII character or one code unit in UTF-8 encoding, which is what this tool uses by default.
They're encoded in UTF-8 first, which can use 2, 3, or 4 bytes per character depending on the character — so a single emoji may expand into several 8-bit groups in the output.
Yes, use the companion Binary to Text tool to reverse the conversion and recover the original characters.
Both represent the same underlying bytes, just in different bases — binary shows each byte as 8 bits (0s and 1s), while hex shows each byte as two hexadecimal digits, which is more compact to read.
The spaces are only for readability — the same data with or without separators represents the identical sequence of bytes.
