About Morse Generator

Morse Generator is a free set of Morse code tools. Type a message and hear it, turn a recording back into text, look up a letter or learn the code by ear. Everything runs in your browser. There's nothing to install and no account to make.

What's on the site

How it works

The site uses International Morse code as set out by the ITU (ITU-R M.1677-1), plus a few common characters outside the standard, such as ! and $. The alphabet page notes which is which.

Sound follows the standard PARIS timing: a dot is 1 unit, a dash 3, the gap inside a letter 1, between letters 3 and between words 7. One unit lasts 1,200 divided by the speed in words per minute, in milliseconds. Farnsworth spacing uses the ARRL formula.

The audio decoder looks for the strongest steady tone in a recording, learns the speed from the signal, and reads dots, dashes and gaps from it. It does this on your device. It's tested on recordings from 10 to 30 WPM and 440 to 800 Hz, including noisy ones, and it can still get letters wrong. Check anything that matters.

What we don't do

  • We don't see what you type, play or record. Text, recordings and microphone sound stay on your device.
  • We don't have accounts, and we don't sell your data.
  • We don't charge for anything. Every tool is free, with no limit.
