One message, three ways to use it
Use the translator for a quick conversion, the audio controls for listening, and the reference pages when you want to understand the result. Each letter becomes a group of dots and dashes. A single space separates letters; / separates words. These boundaries remain visible when you copy the result.
For example, HI THERE becomes .... .. / - .... . .-. .. The gap between HI and THERE is part of the message. Removing it changes the decoded text to HITHERE. The tool accepts a slash or a wider typed gap when decoding, so you can work with several common text formats.
Translate a message step by step
- Choose Text to Morse and enter letters, numbers or supported punctuation.
- Check any warning about unsupported characters. A short result can mean an input character was omitted.
- Select Copy result or download a TXT file. Use Swap to check a short message in the other direction.
- Choose a comfortable speed, pitch and volume before playing audio or downloading a WAV.
Translation happens as you type. The Translate button also works, and Ctrl+Enter or Command+Enter runs the same conversion. Inputs are limited to 500 characters. A longer Morse result can still be copied or downloaded; if it exceeds the input limit, decode it in smaller sections rather than losing the end of the message.
Examples you can check yourself
| Text | Morse output | What to notice |
|---|---|---|
| HELLO | .... . .-.. .-.. --- | Each L is its own group. |
| SOS 2026 | ... --- ... / ..--- ----- ..--- -.... | The word boundary separates letters from the year. |
| A/B | .- -..-. -... | A literal slash is a punctuation signal. |
| READY? | .-. . .- -.. -.-- ..--.. | The question mark has a separate signal. |
Understand the audio controls
Speed is shown in words per minute using the conventional PARIS timing definition. The pitch control changes the tone, while volume changes its level. These controls affect playback and the generated WAV. They do not alter the letter-to-signal mapping.
The duration shown is calculated from the signal elements and gaps at the selected speed. It excludes a trailing silence after the final character. It is not an estimate based only on the number of words. To compare settings, keep the same message and change only one control.
Choose the right Morse resource
- Morse code decoder: work through a typed message and diagnose missing gaps.
- Alphabet: look up a letter and hear its rhythm.
- Printable chart: create a paper or PDF reference.
- Practice quiz: test a small character set with written or listening prompts.
- Spanish and Arabic: use the documented language-specific mapping and normalization rules.
Questions about the translator
Can it decode a recording or microphone input?
No. The decoder accepts typed dots and dashes. The audio functions generate a signal; they do not recognize speech or analyze recordings.
What happens to an unknown character?
Text characters outside the selected map are omitted with a visible warning. Unknown Morse groups are shown as � rather than silently disappearing. Check the warning and compare the result with the input.
Does Morse code preserve lowercase letters?
No. Latin decoding is displayed in uppercase. Text-to-Morse normalizes case before looking up each character.
Is translation text uploaded?
The conversion and audio code run in your browser. Contact submissions are sent to the site, and analytics or advertising services have their own data handling. Read the privacy policy for that distinction.
