Text to Binary Converter
Encode text to UTF-8 binary bytes or decode binary back to text. Handles ASCII, accented characters, emoji, spaces, continuous bits, and line-separated byte groups entirely in your browser.
UTF-8 Aware Binary Conversion
A correct text-to-binary converter must encode text to bytes before writing bits. This tool uses the browser's native UTF-8 encoder, so A becomes one byte, é becomes two bytes, and emoji become four bytes. That matches how text is stored in files, APIs, network payloads, hashes, and Base64 inputs.
Common Binary Formats
Space-separated bytes are easiest to read: 01001000 01100101. Continuous bits are compact and common in puzzles or protocol examples: 0100100001100101. Line-separated output is useful when inspecting long strings byte by byte.
Frequently Asked Questions
How does text to binary conversion work?
Text is first encoded as bytes, usually with UTF-8. Each byte is then written as an 8-bit binary number. ASCII characters such as A use one byte, while emoji and many non-Latin characters use multiple UTF-8 bytes.
Can I decode binary without spaces?
Yes. Paste either continuous bits like 0100100001100101 or space-separated bytes like 01001000 01100101. The input must still contain complete 8-bit bytes.
Does this support Unicode and emoji?
Yes. The converter uses TextEncoder and TextDecoder with UTF-8, so emoji, accented characters, and CJK text round-trip correctly.
Is this data uploaded to BytePane?
No. Conversion runs locally in your browser. Your text and binary output are not sent to a server.
