What this site is for
The site is designed to help people complete practical Morse code tasks without creating an account. The main translator converts text to Morse code and Morse code back to readable text. Other pages focus on distinct jobs such as decoding Morse from audio, detecting dots and dashes in an image, learning the alphabet, practicing recognition, checking timing, and understanding common signals such as SOS.
We try to keep each page focused on a real task rather than publishing many near-duplicate pages for slightly different search phrases. When a separate page exists, it should provide its own useful interaction, reference value, or explanation.
How the tools work
Many of the site's core functions run directly in the browser. Translation and playback use browser-side JavaScript and Web Audio features. The image translator uses Canvas and JavaScript to inspect graphic Morse marks on the current device. The audio decoder analyzes uploaded audio or microphone samples locally in the browser rather than sending the recording to a remote transcription or AI decoding API.
Keeping these tasks local makes the tools fast to try and reduces the amount of source material that needs to leave a visitor's device. It also creates clear limitations: browser-based detection can be affected by noise, unusual spacing, poor image contrast, overlapping marks, microphone quality, and browser support.
Accuracy and educational use
The site aims to follow standard International Morse Code conventions for dots, dashes, letters, numbers, punctuation, and timing. Interactive tools can still produce imperfect results when the input is ambiguous or noisy. Confidence indicators, detected groups, playback, and editable outputs are intended to help users inspect a result rather than treat every automatic decode as infallible.
morse-code.org is an educational and utility website. It is not an emergency communications service, a radio licensing authority, or a substitute for official emergency channels. Pages that demonstrate SOS or other emergency signals are for learning and practice.
Privacy by product design
The site does not require an account for ordinary use. Important image and audio decoding workflows are intentionally processed on the current device. The Privacy Policy explains local processing, microphone access, share links, advertising cookies, third-party services, and the privacy choices available to visitors.
Advertising and sustainability
The site may use advertising, including Google AdSense, to help cover hosting, maintenance, and continued development. Advertising is not intended to replace the main content, imitate navigation, or require visitors to click an ad in order to use a core tool.
Feedback and maintenance
Browser changes, unusual recordings, language-specific Morse mappings, and implementation bugs can create errors. If you find a broken control, an incorrect mapping, a decoding problem, an accessibility issue, or a privacy concern, please report it through the Contact page. Clear reports with the affected URL, browser, and reproduction steps are especially useful.
