Translate text to Morse code or decode Morse to English, then play it as sound, light or vibration at true timing. Free, with no sign-up – and it all runs in your browser.
Try an example:
Each letter shows here with its dots and dashes. Select one to play from it.
Each character is drawn to scale: a dash is three dots long and every gap is one dot. Select any character to hear it and see how it is timed.

Check any of these by hand against the Morse code alphabet chart. Each one is a Morse code sample you can play: pick SOS, Hello, I love you or Help under the empty box, or paste any line into the translator and press Play.
Text to Morse code
SOS
... --- ...
HELLO
.... . .-.. .-.. ---
I LOVE YOU
.. / .-.. --- ...- . / -.-- --- ..-
HELP
.... . .-.. .--.
73 (best regards, in radio shorthand)
--... ...--
And the other way, from Morse to English:
.... .. / - .... . .-. .
HI THERE
-.-. --.-
CQ (calling any station)
--. --- --- -.. / -- --- .-. -. .. -. --.
GOOD MORNING
The whole alphabet, the numbers 0 to 9, punctuation and accented letters each have a page with sound. The most famous signal of all has its own page: SOS in Morse code.
Type or paste your message into the box. Text to Morse is the default; if you paste dots and dashes, the translator offers to switch to Morse to text.
For Morse to English, put one space between letters and a slash (/) between words, like .... .. / - .... . .-. . for HI THERE. Three spaces also count as a word gap.
Pick a code table if your message isn’t International Morse: American, Russian, Greek, Hebrew, Arabic, Japanese or Korean.
Press Play to hear it, or switch to Light or Vibrate. Set the speed (5 to 40 WPM) and the tone (300 to 1000 Hz) on the sliders.
Copy the result, share it as a link or a puzzle, or download it as a WAV or MP3 file or a text file.
One Morse translator for both directions: a Morse code converter from text, and a decoder back to English.
Type English and the Morse code encoder writes each letter as dots and dashes as you go, with one space between letters and a slash between words: HELLO becomes .... . .-.. .-.. ---. Numbers and the ITU punctuation marks are covered too.
To copy it one word per line or with · and — symbols, use the English to Morse code translator.
Paste Morse and the decoder reads it back as text, even with the look-alikes copy and paste produces (·, •, —, –, _). Tap it in with the dot and dash keys, or have the result read aloud. Codes that aren’t in the table show as ?.
Morse is a public code, not a cipher, so as a secret code translator it works best as a game: share it as a puzzle and your friend types the answer. To read a message letter by letter, open Morse code to English.
| Code table | Used for |
|---|---|
| International | The ITU standard: English and most languages written in Latin letters, plus É, Ä, Ö, Ü, Ñ and the other accented letters in on-air use |
| American (Railroad) | The original 1840s landline code, with its spaced letters and long dashes |
| Russian (Cyrillic) | Russian and other Cyrillic text |
| Greek | Greek letters |
| Hebrew | Hebrew letters, final forms sent as their base letter |
| Arabic | Arabic letters |
| Japanese (Wabun) | Kana, sent with the Japanese Wabun code |
| Korean (SKATS) | Hangul, sent with the Korean SKATS mapping |
Morse code in Spanish uses the International table plus Ñ (--.--), so pick International for Spanish, French or German.
The translator follows the International Morse code of ITU-R Recommendation M.1677-1. Morse is timed in units: a dot is one unit and a dash is three. The gap inside a letter is one unit, between letters three, and between words seven. Speed is counted in words per minute using the standard word PARIS, which is exactly 50 units long with the word gap after it, so at 20 WPM one unit lasts 60 milliseconds. Playback, the light and the downloaded audio all use these units, which is why the result sounds like real CW and not a string of evenly spaced beeps.

Everything you need to know about the translator
Yes. Morse code is a fixed table of dots and dashes, so any message can be translated letter by letter in either direction. Type text into the translator above to get Morse, or paste Morse to read it in English. For Morse you hear rather than read, the audio file decoder and the microphone decoder turn beeps into text.
Paste it into the translator and switch to Morse to text: the English appears as you type. Leave one space between letters and a slash between words, so .. / .-.. --- ...- . / -.-- --- ..- reads I LOVE YOU. Underscores and pasted symbols like · and — count as dots and dashes, and any code the table doesn’t know shows as a question mark.
Split the message into letters at each space or short pause, look each pattern up in the Morse code alphabet, and read a slash or a longer pause as the gap between words. Or paste the dots and dashes into the translator above and switch to Morse to text. For Morse you hear or see, the audio, microphone, light and picture decoders read it for you.
Not a message you already have. Google Translate doesn’t support Morse code, and Gboard, Google’s phone keyboard, has a Morse input for typing in dots and dashes but doesn’t read a message back to you. To decode one, paste it into the translator above, or use the audio decoder for a recording or video.
You don’t need to install one. This translator and its decoders work in any phone browser: paste dots and dashes, play a recording, point the microphone decoder at the sound or the light decoder at a flashing lamp. Nothing is uploaded, and you can add the site to your home screen to open it like an app.
No. Morse code is not one of the languages Google Translate supports, so it can’t turn dots and dashes into words or back. Morse is a code for letters rather than a language, and a Morse code translator like this one does the job directly: it converts both ways, plays the result as sound or light, and runs in your browser.
No. 143 is a pager-era number code for I love you (1, 4 and 3 are the letters in each word), not Morse code. In Morse, I love you is .. / .-.. --- ...- . / -.-- --- ..-, and the number 143 is .---- ....- ...--. The I love you in Morse code page plays it and links to tools that flash it or make it into a bracelet, necklace or tattoo.
The International Morse alphabet has 26 letters, from A .- and B -... to Y -.-- and Z --.., plus the digits 0 to 9 and the punctuation marks. E is the shortest letter, a single dot, and T is a single dash. The chart below the translator draws every letter to scale, and the Morse code alphabet page lists them all with sound.
Three dots, ..., are the letter S. Three dashes, ---, are O, so ... --- ... is SOS. Dots make different characters depending on how many sit together: E is one dot, I two, S three, H four and the digit 5 five. Eight dots in a row is the error signal operators send to cancel a mistake. Paste any pattern into the translator to read it.
Tap short for a dot and about three times as long for a dash, with a short pause between letters and a longer one between words. The Morse keyboard turns taps on one key or two, or a touch screen into letters as you go, so you can check what you sent. Knocking on a wall is usually tap code, a different code with its own translator.
Morse code writes letters as short and long signals, dots and dashes, that can be sent as sound, light or taps. Each letter has its own pattern: E is one dot, T is one dash, and SOS is ... --- .... Samuel Morse and Alfred Vail made it for the electric telegraph in the 1830s and 1840s. What is Morse code? explains how it works.
Yes. Amateur radio operators send and receive it every day, and aviation radio beacons called VORs still identify themselves in Morse code, which pilots check before relying on them. People with limited movement also use it to type with one or two switches. It is popular for gifts, tattoos and puzzles too, and easy to learn by ear with the Koch course.

This free Morse code translator works online in your browser: the text you type, the audio and the light are made on your device and nothing is uploaded.
A shared link carries the message after the # in the address, which never reaches our server.
The translator reads standard dots, dashes and gaps; it does not decode audio, which is what the audio file decoder is for. Characters a code table doesn’t have are left out and named under the box.
Timing follows ITU-R M.1677-1. Maintained by Translate Morse Code, an independent site; last updated October 2026.
