About Morse Code Translator
The translator has two linked boxes. Type plain text and the Morse appears instantly; type or paste Morse and the text decodes as you go. It uses the International Morse alphabet, covering the 26 letters, the digits 0-9, and common punctuation such as the period, comma, question mark, slash and at sign.
Within Morse, letters are separated by a single space and words by a forward slash (/). Dots and dashes map to the standard code, and the decoder is tolerant of common variants while marking anything it cannot resolve, so pasted Morse from different sources still translates cleanly.
A "Play as audio" button sounds the Morse as a 600 Hz tone using the Web Audio API, at roughly 15 words per minute, with correct timing - a dash lasts three times as long as a dot, and gaps between letters and words follow the standard proportions. No audio files are downloaded; the tone is synthesized locally.
Because both the translation and the sound are generated client-side, the tool works offline and keeps your text private. Hearing the rhythm is how operators actually read Morse, which makes the audio playback especially useful for learning the code by ear.
How to use it
- 1Type plain text in the left box to generate Morse, or paste Morse in the right box to decode it back into text.
- 2In Morse, separate letters with a single space and words with a forward slash (/) so the translator groups them correctly.
- 3Click "Play as audio" to hear the Morse as a 600 Hz tone at about 15 words per minute.
- 4Copy the contents of either box; everything runs locally, so no text or audio leaves your device.
Common use cases
- -Learning to recognise Morse code by ear through synthesized tone playback
- -Encoding short messages or call signs for amateur radio practice
- -Decoding Morse you have written down or received into readable text
- -Adding Morse puzzles or Easter eggs to games, escape rooms and events
- -Teaching the International Morse alphabet and its timing in a classroom
Frequently asked questions
- How are words separated in Morse code here?
- Letters are separated by a single space and words by a forward slash (/). For example, "hi there" is coded with the letters of each word spaced apart and a / placed between the two words.
- Can this tool play Morse code as sound?
- Yes. The "Play as audio" button synthesizes the Morse as a 600 Hz tone at roughly 15 words per minute using the Web Audio API, with a dash lasting three times as long as a dot. No sound files are downloaded.
- Does it translate in both directions?
- Yes. Typing text produces Morse and typing Morse produces text, and the two boxes stay in sync as you edit either one, so it works as both an encoder and a decoder.
- Which characters can it convert?
- It supports the International Morse alphabet: the 26 letters, digits 0-9, and common punctuation such as the period, comma, question mark, slash and at sign. Unsupported symbols are skipped or marked when decoding.
- Is my text uploaded to translate it?
- No. Both the translation and the audio are generated entirely in your browser, so the tool works offline and your text never leaves your device.
