Morse Code Translator

1. 1

   Type or paste your message

   Enter text in the left box. The Morse code appears in the right box as you type — there is no Convert button to press.

2. 2

   Translate in either direction

   Paste dots and dashes into the right box to turn them back into letters. The tool accepts ., · and • for dots, and -, _ or — for dashes.

3. 3

   Listen and adjust the timing

   Press Play to hear the message. Change the speed, pitch and volume, or download a WAV file that you can keep or share.

4. 4

   Share or hide the answer

   Create a link to your message, or tick Puzzle link to send a version that hides the original text behind a Reveal answer button.

The WAV button turns the message into an audio file without sending anything to a server. The file is mono, 44.1 kHz and 16-bit PCM, so it plays in ordinary audio apps and can be attached to a lesson, a puzzle or a message.

Use the speed and pitch controls before downloading if you want a specific sound. The speed follows the PARIS standard: a dot is one unit, a dash is three units, and the gaps between letters and words are fixed multiples of that unit. A lower WPM makes the code easier to follow; a higher WPM makes a shorter file.

The filename is built from the first letters of the plain text, for example morse-hello-world.wav. Downloading the WAV does not change the message in the translator, so you can keep editing and generate another file at any time.

Morse code represents letters, numbers and punctuation with short signals (dots) and long signals (dashes). It was developed in the 1830s and 1840s for the electric telegraph and became the first widely used digital code: every message is built from just two states, on and off.

The international version used today was standardized by the ITU. A, for example, is .- and S is ..., while the famous distress call SOS is ... --- ... — three dots, three dashes, three dots. SOS was chosen because it is easy to recognize, not because the letters stand for words.

Morse is defined by timing, not by the exact sound. In the PARIS standard a dot is one unit long, a dash is three units, the gap between symbols inside a character is one unit, the gap between letters is three units, and the gap between words is seven units. At 20 words per minute one unit is 60 milliseconds.

Farnsworth timing keeps the characters fast but stretches the gaps so beginners can follow. That is why a 10 WPM Beginner preset can sound like 10 WPM characters with extra breathing room, rather than slow, evenly spaced beeps.

Amateur radio operators still use Morse for weak-signal contacts, and aviation uses Morse identifiers for navigation beacons. Scouting, emergency-preparedness groups and puzzle games keep the alphabet alive for a new generation.

Because it works with a light, a buzzer or a radio tone, Morse is also a useful accessibility tool. The shape of the signal matters more than the sound.

The fastest route to Morse is to learn characters as sounds, not as counts of dots and dashes. Counting is fine for reading a table, but it collapses at real speed because there is no time to count each mark. Koch-style practice introduces two characters at a time at a character speed of 15–20 WPM and adds a new character only when the current pair is reliable.

Farnsworth spacing is a learning aid, not a different code. Keep the character speed high enough that each letter has a distinct rhythm, then increase the overall speed by shrinking the gaps. Five to ten minutes a day is more effective than one long weekly session, and copying complete words is easier than copying isolated letters.

• Forgetting the gap between words

  A single space separates letters, while a slash (or three spaces) separates words. Without word gaps, a sequence such as ... --- ... can be read as one long group of marks.

• Sending faster than you can copy

  Speed is useful only after the characters are familiar. Beginners should practice at 10–15 WPM and keep the character rhythm steady instead of rushing individual letters.

• Assuming every punctuation mark is standard

  The ITU table covers the common marks, but some punctuation and accented letters have local or unofficial codes. This translator marks characters it cannot encode.

• Learning by sight instead of sound

  Flash cards help with the table, but real Morse is copied by ear. Practice hearing a character as one rhythm; otherwise your speed will stall as soon as several letters arrive together.
