Encode or decode letters and digits

For a technical exchange, a coding lesson or a conversion check, this gives learners and developers a readable result. Encode or decode letters and digits.

Encode or decode letters and digits. The result appears instantly in your browser, ready to copy, with no account, upload or storage involved.

How to use

Paste or type the text you want to encode into the input field, or enter dots and dashes with slashes between words.
Select the encoding action to turn letters and digits into Morse code.
Switch to extended encoding when your message contains additional characters supported by the tool.
Run the main action and read the converted string directly beneath the input area.
Copy the output, or use decoding to turn a Morse sequence back into readable text.

Example

Using SOS 123 as the input, encode it and watch how letters, digits and words are separated. The output should remain reversible: decode it again and check that you get the original text back. This is a quick way to confirm spacing before sending a message.

Input

SOS 123

Output

... --- ... / .---- ..--- ...--

Limits and formats

The converter is intended for letters and digits, so check how it treats punctuation, accents and other symbols before relying on them.
A slash marks the boundary between words in Morse; without it, decoding may split the sequence differently.
Extended mode covers only the extra characters the tool recognises, so test your own symbol set first.
If you load a text file, proofread the output because automatic conversion can expose unsupported characters.

Where processing happens

The conversion runs entirely in your browser. The text you enter stays on the page, is processed locally and is not uploaded. Once the page has loaded, you can use the tool offline, and nothing is kept after you close or clear the fields.

Frequently asked questions

How should I separate words in a Morse message?

Place a slash between words, as shown in the input hint. Letters are separated by spaces. If you leave out the slash, the decoder may join two words or split them at the wrong point, so review the result carefully.

What is extended encoding for?

Extended encoding handles characters beyond the basic Morse set. Try a short sample containing your symbols, then decode it to see whether the round trip is exact. Not every special character is guaranteed to work.

Can I decode Morse copied from another source?

Yes, if the spacing follows the same convention of spaces between letters and slashes between words. Paste the sequence, choose the decoding action and inspect the returned text, because irregular gaps can change the reading.
