Morse code conversion supports "text → Morse" and "Morse → text". English letters, digits and the punctuation in its table are converted with the Morse table; Chinese is first turned into pinyin words in the browser with pinyin-pro and the pinyin letters are then encoded, so decoding returns Latin letters/pinyin and never restores the original Chinese characters automatically.

1. 01Choose text to Morse or Morse to text.
2. 02When encoding, type Chinese, English or digits; Chinese is converted to pinyin first. When decoding, separate letters with spaces and words with /.
3. 03Read the live result and the "skipped" notice, then copy it or download a TXT.
4. 04To listen, set 5–40 WPM and 400–1000 Hz, then press play.

• Chinese depends on the app's on-demand pinyin-pro module; if it fails to load an error is raised and the input is never sent to a pinyin API.
• Characters that cannot be mapped are skipped and listed; no arbitrary Unicode character is guaranteed to be encodable.
• Playback is generated on the machine by the Web Audio AudioContext and a sine oscillator; playback is unavailable when the browser does not support Web Audio.
• Morse text longer than 5,000 characters is refused for playback, while text conversion itself has no such playback limit.
• A dot is 1 time unit and a dash 3; letter and word gaps are padded by the implementation to 3 and 7 units.

Input, pinyin conversion, Morse encoding and decoding, and audio synthesis all happen locally in the browser; the tool itself does not keep your input and does not send text to a third party.
