Text to Binary Converter
Output
Type on the left to convert.
Text to binary, Unicode, Roman, and NATO
Convert human text to UTF-8 bits, code points, Roman numerals (1–3999), or the ICAO spelling alphabet. For Base64 see the Base64 encoder. Identifier case lives on the case converter.
Text to binary FAQ
- Is text to binary UTF-8 or UTF-16?
- UTF-8 bytes. Each byte is eight 0/1 bits. JavaScript strings are UTF-16 in memory; this page encodes with TextEncoder so “é” is two bytes, not one.
- Does this only work with ASCII?
- No. Hindi, emoji, and other Unicode convert as UTF-8. Reverse needs a multiple of 8 valid bits.
- What Roman numerals are allowed?
- Standard forms from 1 to 3999. 1994 is MCMXCIV. IIII and 0 are rejected.
- Is NATO phonetic encryption?
- No. It is ICAO spelling so letters can be read over a radio. It is not a cipher.
- Where is integer base conversion?
- Number bases (hex, binary integers) stay on the computer science calculator. This page rewrites human text.

Examples
Hi as bits
UTF-8 Hi is 01001000 01101001 when grouped by byte.
Limitations
- Input is capped at 10,000 characters.
- Roman numerals are 1–3999 standard forms only.
- NATO is spelling, not encryption.
