About Morse Code Free

Morse Code Free is a small set of Morse code tools: a translator that works in both directions, a printable alphabet chart you can listen to, an audio decoder and a practice trainer. They run in your browser on phones, tablets and computers. There is nothing to install and no account to create.

The tools follow international Morse code as defined by the ITU (Recommendation M.1677), with standard PARIS timing for speed and the ARRL formula for Farnsworth spacing. Sound, light and audio files are all made in your browser.

Your settings and trainer progress are saved only in your own browser. The microphone and audio files used by the decoder are processed on your device and never uploaded.

The site is free to use and funded by ads.
