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.
Set crop edges or straighten a tilted row
Crop values are percentages of the current image. Keep the whole row of marks.
Green boxes belong to valid letter groups; red boxes need review. Tap a box to select its Morse group below.
Type a message or edit the Morse code. Both directions work.
One space separates letters. Use / or three spaces between words. Dots and dashes within one letter stay together.

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.
