Image Morse Code Translator

Morse Code Decoder

Decode Morse code back into plain text — from a picture of dots and dashes, a recording of beeps, or Morse you paste in. This Morse code decoder does all three, entirely on your device.

A Morse code decoder takes dots and dashes and gives you back the message. What makes this one different is that it decodes Morse from three kinds of input, not just typed characters: a picture of Morse (a photo, scan or screenshot), an audio clip of beeps, or Morse you paste as text. Pick the tab that matches what you have and it rebuilds the letters and words for you.Under the hood the decoder measures, it does not guess. For an image it thresholds the marks and measures each one's width — short marks are dots, long marks are dashes. For audio it times every beep and silence in milliseconds. For pasted Morse it maps each dot-and-dash pattern against International Morse. In every case the gaps decide where one letter or word ends and the next begins, so the decode follows the same 1-3-7 timing the code is actually built on.Because it all runs locally, nothing you decode is uploaded — useful for puzzle solutions, escape rooms, ham-radio practice and geocache clues. If the automatic read is slightly off you are never stuck: adjust the threshold, flip invert for light-on-dark images, or edit the detected Morse by hand and the plain-text translation updates instantly. To go the other way and turn text into Morse, use the generator; for a letter-by-letter reference, see the Morse code alphabet.

Frequently asked questions

What can this Morse code decoder read?

Three things: an image of Morse code (photo, scan or screenshot), an audio recording of Morse beeps, and Morse you paste in as dots and dashes. Switch tabs at the top of the tool to choose your input.

Is the Morse code decoder free and online?

Yes — it is a free online decoder with no sign-up and no install. It runs in your browser, so once the page has loaded it even works offline.

How do I decode Morse from an image?

Drop the picture on the image tab. It converts to grayscale, separates the marks with an automatic threshold, and measures each mark to tell dots from dashes. A preview shows exactly what it detected so you can fine-tune it.

The decode is not perfect — can I correct it?

Yes. Move the threshold slider, toggle invert, or simply edit the detected dots and dashes; the decoded text re-reads as you type, so there is always a manual fallback.
