About Digital Morse

Who we are

Digital Morse (morse-code.co.uk) is operated by Space Bits, S.L., a web development company based in Manresa, Spain. We build focused, fast web tools rather than large platforms, and Digital Morse is one of them.

Why we built Digital Morse

Morse code is still used and taught today in amateur radio, aviation, scouting, and emergency signalling, and people regularly need a fast, accurate way to translate, listen to, or look up Morse code. We wanted to build something simple and genuinely useful: tools that work well, rather than a page built mainly to rank in search results.

Morse code and Britain

Digital Morse is operated by a Spain-based company, but we chose the .co.uk domain deliberately: wireless Morse communication has deep roots in Britain. Guglielmo Marconi carried out his first practical wireless telegraphy experiments in England after arriving in 1896, filing the world's first wireless telegraphy patent in London that same year. In December 1897 he built the first permanent wireless station at the Needles Hotel on the Isle of Wight, and by 1898 it was reliable enough for Queen Victoria to send messages to her son, Prince Edward, aboard the royal yacht nearby.

Britain's connection to Morse also runs through maritime history: RMS Titanic, registered in Liverpool and operated by the White Star Line, was fitted with Marconi wireless equipment and sent Morse distress calls when she sank in 1912. The disaster led directly to the first International Convention for the Safety of Life at Sea, convened in London the following year (see our SOS page for more on this).

How the tools work

The translator maps each letter, number, and common punctuation mark to its standard International Morse Code representation, and back again. Text-to-Morse and Morse-to-text conversion happen instantly in your browser as you type.

Morse audio is generated in your browser using the Web Audio API. Each dot and dash is played as a short tone at the speed (WPM), pitch, and volume you choose, following the standard Morse timing ratios: a dash lasts three times as long as a dot, with proportional gaps between letters and words.

We are also working on tools to decode Morse code from an uploaded audio file or a microphone recording. These are not available yet. When they launch, this page will be updated to explain exactly how they work and what their limitations are.

Accuracy and maintenance

Morse character mappings on this site are checked against Recommendation ITU-R M.1677-1, the official International Morse Code standard. Historical claims are checked against the sources listed below, favouring primary and institutional sources over general reference sites where possible. Content is reviewed periodically and updated when sources, standards, or the site itself change.

If you notice an error, please contact us using the details below and we will investigate and correct it.

Content reviewed: August 2026.

Sources and further reading

The technical and historical information on this site is checked against publicly available sources. We try to favour primary and institutional sources first:

Primary / official

• Recommendation ITU-R M.1677-1, International Morse Code — the official Morse code standard published by the International Telecommunication Union, the United Nations agency for telecommunications.
• Samuel Finley Breese Morse: Artist and Inventor — Smithsonian National Museum of American History, for the origins of the telegraph and Morse code.

Established reference works

• Samuel F. B. Morse — Encyclopaedia Britannica, for biographical context.

General background

• Morse code — Wikipedia, for general background and terminology.
• SOS — Wikipedia, on the history and adoption of the distress signal.

We link to these sources for transparency, not as an endorsement of this site by the organisations listed.
