Codificador / Decodificador Base64
Decodifique código Morse escribiendo puntos y guiones o tocando el botón interactivo de toque.
Acerca de esta herramienta
Pegue o escriba código Morse usando puntos (.) y guiones (-) separados por espacios entre letras y barras (/) entre palabras, y el texto decodificado aparece al instante mientras escribe. Para una experiencia práctica use el botón de toque: los clics cortos producen puntos y las pulsaciones largas (300 ms+) producen guiones — igual que una clave telegráfica real. El decodificador etiqueta cada grupo Morse con su carácter decodificado encima para que pueda detectar errores de un vistazo. Una tarjeta de referencia integrada muestra el alfabeto Morse ITU completo incluyendo puntuación común.
Cómo usar
- 1 Escriba o pegue código Morse en el cuadro de entrada usando puntos (.), guiones (-), espacios entre letras y / entre palabras.
- 2 El texto decodificado se actualiza en vivo encima de cada grupo de puntos y guiones.
- 3 Alternativamente, haga clic en el botón 'Toque' con toques cortos para puntos y pulsaciones largas (≥300 ms) para guiones para ingresar Morse de forma interactiva.
- 4 Consulte la tarjeta de referencia en la parte inferior para ver el alfabeto Morse completo y la tabla de puntuación.
Reading Morse the other way: from dots and dashes back to text
Encoding text into Morse is the easy direction — every letter has exactly one pattern. Decoding is harder, because the receiver has to figure out where one character ends and the next begins purely from the gaps. This tool takes the marks you give it — dots (.), dashes (-), spaces, and the word separator / — and turns them back into plain text, character by character. It is built for the receiving side of Morse: copying a signal you heard, transcribing a recording, or checking a code you wrote by hand.
The three levels of spacing the decoder relies on
Because dots and dashes are written with the same two symbols for every letter, the spacing is the grammar. This tool reads three distinct separators, and getting them right is the whole game:
| Separator | You type | Meaning |
|---|---|---|
| Symbol gap | (nothing) | Dots and dashes touching form one letter: ... is S |
| Letter gap | one or more spaces | Ends a letter, starts the next: ... --- is two letters |
| Word gap | / (slashes, spaces optional) | Ends a word, inserts a space in the output |
Internally the decoder splits your input on / to find words, splits each word on whitespace to find letters, then looks each dot-dash token up in the International Morse table. Any token it cannot find is rendered as a literal ? so you can see exactly where decoding failed rather than silently dropping it.
A worked example
Type .... . .-.. .-.. --- / .-- --- .-. .-..-. -.. into the box. The decoder splits on the / into two words. In the first, the five space-separated tokens ...., ., .-.., .-.., --- map to H, E, L, L, O. The second word .-- --- .-. .-..-. -.. becomes W, O, R… then .-..-. resolves to a double-quote and -.. to D — so a stray symbol shows up immediately as the wrong character. The annotated view stacks each decoded letter above its dot-dash token, making it obvious which group produced which character, and the large decoded text line shows the final string you can copy.
Tapping it out instead of typing
The tool also has a tap pad that turns timing into symbols the way a real telegraph key does. A quick press registers a dot; holding the button for 300 ms or more registers a dash. Then it watches the silence: about one second of no tapping ends the current letter and decodes it, and a further pause inserts a word break (/). This is a hands-on way to feel why spacing matters — tap . then pause too long and you have sent E followed by a new letter, not the start of a longer code.
Why decoding is genuinely ambiguous
The deep problem in Morse reception is that without clear gaps, a stream is ambiguous. The sequence ...-.- could be SV, UR, or several other readings depending on where you place the letter breaks. A human operator resolves this with rhythm and context; this tool resolves it strictly from the spaces you provide. That is the single most important thing to understand: the decoder is only as good as your gaps. If you run letters together with no spaces, it will try to match the entire run as one impossibly long token and return ?.
Common mistakes and how to avoid them
- No spaces between letters. Writing
...---...as one block asks the tool to find a single nine-element character. (That specific run happens to be mapped to the SOS prosign, but....jammed against.will not split into H and E.) Put a space between every letter. - Mixing up the word separator. Use
/for word breaks. Multiple spaces alone are all treated as a single letter gap, so two words will merge. - Wrong dash character. Type a plain hyphen
-, not an en-dash or em-dash pasted from a document. Only the ASCII dot and hyphen are recognised. - Expecting it to guess letter breaks. It will not infer where one character ends; that is information only the gaps carry.
Practical uses
Decode a signal you copied by ear during ham-radio practice, transcribe Morse from an old film or audio clip, check homework or a puzzle answer, or verify that a code you encoded round-trips back to the right text. A built-in reference card lists the full alphabet, digits, and punctuation so you can look up any character while you work. Everything runs locally in your browser — the marks you paste are decoded on your own device and never sent anywhere.
