Converted locally in your browser with UTF-8 safe TextEncoder and TextDecoder handling. Your text stays only on this page.
Encode text as binary
Convert plain text into a space-separated Base2 (binary) byte string with eight bits per byte. Unicode text is encoded as UTF-8 first, so emoji and non-Latin characters are handled correctly.
When to use this tool
Use binary encoding when you want to see how characters map to bytes, build teaching examples, debug bit-level data, or hand-write puzzle and CTF fixtures.
Privacy and limitations
This conversion runs locally in your browser. Binary is an encoding format, not encryption, so anyone can decode the result if they have the encoded text.
