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.

Encode text into Morse code and decode Morse back into text, with letter and word spacing handled for you. Everything is translated 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

Is Morse code still used today?

Yes, though rarely commercially. Amateur radio operators use it because a Morse signal cuts through noise and weak conditions where voice fails, and aviation beacons still identify themselves in Morse.

How is spacing represented?

A space separates letters and a forward slash separates words, which is the standard written convention. In transmitted Morse the equivalent is timing: a gap of three units between letters and seven between words.

What is SOS in Morse code?

Three dots, three dashes, three dots, sent as one continuous string with no letter gaps. It was chosen purely because that pattern is unmistakable and easy to send under stress — it is not an abbreviation for anything.
