About Text Translator

Covers all three in both directions, including 8-bit binary and the NATO alphabet — the one people reach for when reading a serial number or a postcode aloud without being misheard.

Convert text into 8-bit binary and binary back into text using standard UTF-8 encoding. The translation runs entirely in your browser.

Encode and decode Morse code, spell text out with the NATO phonetic alphabet, or convert text to and from 8-bit binary. It is a fun and practical helper for learning Morse, dictating codes clearly over the phone, or understanding how text maps to binary.

Switch between the three modes and translate in either direction. Morse and binary round-trip exactly; NATO is encode-only, because reading a phonetic spelling back is something people do rather than software.

Frequently asked questions

How does text become binary?

Each character maps to a number via a character encoding, and that number is written in base two. In ASCII, capital A is 65, which is 01000001 as eight bits. Text in binary is just those numbers written out.

Which encoding is used?

UTF-8, the web standard. Plain English maps one character to one byte, matching ASCII exactly, but accented letters, emoji and non-Latin scripts use two to four bytes — so their binary is correspondingly longer.

Does converting to binary hide or protect my text?

Not at all. Binary is a representation, not encryption — anyone can convert it straight back. If you need the content protected, use real password-based encryption.
