Morse Code Decoder

This Morse Code Decoder decodes dot-dash sequences into readable text in real time. It is designed for students learning Morse, amateur radio operators, field technicians, and translators who routinely encounter Morse transmissions or transcripts and require quick, accurate transcription without audio playback. Users can type or paste Morse input in standard .- and -.. formats and immediately see the corresponding text, with default capitalization and basic punctuation handling.
Under the hood, the tool uses a fixed International Morse mapping for letters, digits, and common punctuation. It tokenizes input by spaces, treats single spaces as letter separators, and uses '/' or multiple spaces to mark word breaks. It handles common edge cases such as extra spaces and mixed separators, and runs entirely in-browser for offline use with no server data required. It also produces a simple, readable output that can be copied to notes or documents.
A key differentiator is real-time feedback with robust handling of spacing irregularities and unknown codes. When a pattern is not recognized, a clear placeholder like is produced to aid debugging and learning. It supports basic punctuation, numbers, and several common prosigns to improve transcription practicality. The approach emphasizes deterministic decoding and predictable results across varied Morse inputs.
Typical use cases include classroom practice, field transcription during demonstrations, quick note taking from signals, amateur radio sessions, and informal language learning. The tool focuses on accuracy, speed, and accessibility, and is suitable for both beginners and experienced users who need fast Morse-to-text conversion, auditing practice transcripts, or offline study environments.
