Who it is for

About Morse code

Morse code represents letters, numbers and punctuation as short and long signals — dots (dits) and dashes (dahs). Amateur radio, aviation and emergency signalling still use it; SOS (... --- ...) is the best-known distress rhythm.

This site uses the International Morse standard, so what you encode or decode here matches common charts and on-air practice worldwide. Type on the Text side to encode; paste dots and dashes (ASCII .- or pretty ·—) on the Morse side to decode. Word gaps show as /.

We do not do photo OCR, AI image decode, or license-exam coaching. If you need a full phrase as sound, use Play on the converter or the audio translator. For structured drills, open the trainer.

Common questions

Is this International Morse or American Railroad Morse?

International Morse (ITU-style letters, digits, and common punctuation). If an old railroad chart disagrees, you are probably looking at a different alphabet.

Does my text leave this device?

No. Encode, decode, and audio run locally in your browser. There is no account and nothing is uploaded for translation.

Why is not sound playing?

Most browsers block autoplay. Click Play once after the page loads - that user gesture unlocks Web Audio. Silent failure is usually a permission rule, not a broken tone.

What does WPM mean here?

Words per minute using the common PARIS standard (dit length ≈ 1200 / WPM ms). Higher WPM shortens dits and dahs; pitch only changes the tone, not the timing.

Can I learn Morse here, or is this only a converter?

Both. The homepage is the converter on purpose. Trainer (Koch / Farnsworth), listening practice, and keyer are linked below when you want drills.

Is this for emergencies or a license exam?

No. MorseLabBase is a practice and translation tool - not emergency certification and not a substitute for official training or safety-critical procedures.

Practice tool only - not a license exam, not emergency training certification. Audio and light stay in your browser.
