Morse Code Translator

What this tool does

This translates plain text into Morse code and Morse code back into plain text, live as you type in either box — no need to pick a direction first. It also actually plays the Morse code as audio using real oscillator beeps timed to standard Morse spacing (not just a text animation), with a speed control measured in words per minute, the same unit real operators use, plus a synced flash-light indicator.

How to use it

• Type in the Text box to see it converted to Morse instantly, or type dots and dashes directly into the Morse Code box to decode it back to text.
• Separate letters with a single space and words with / when typing Morse manually — that's standard Morse notation and what this tool outputs too.
• Adjust the Speed slider (in words per minute) and the Tone slider (pitch in Hz) to match how you want the audio to sound.
• Click Play Audio to hear it, or Stop to cut it off early.
• Use the reference grid at the bottom to look up any letter or number's Morse pattern directly.

Real-world use cases

• Studying for an amateur (ham) radio license exam that tests Morse code recognition.
• Decoding a Morse message from a puzzle, geocache clue, or escape room.
• Practicing sending and recognizing Morse at a specific words-per-minute speed before using a real telegraph key.
• Encoding a short message in Morse for a novelty gift, tattoo, or prop.

Frequently asked questions

What timing standard does the audio use?

The classic "PARIS" standard: a dash lasts three times as long as a dot, the gap between symbols within a letter equals one dot, the gap between letters equals three dots, and the gap between words equals seven dots — all scaled by your chosen words-per-minute speed.

How do I write Morse code by hand for this tool to decode?

Use a period (.) for a dot, a hyphen (-) for a dash, a single space between letters, and a forward slash (/) between words — for example ... --- ... decodes to "SOS".

Does it support numbers and punctuation, not just letters?

Yes — digits 0–9 and common punctuation (period, comma, question mark, and more) are all included, matching the international Morse code standard.

Why can't I hear the audio?

Browsers require a user interaction before playing audio, so make sure you've clicked "Play Audio" directly (not just loaded the page), and check your device volume isn't muted.
