Morse Code Translator

Encode text into International Morse and decode dots/dashes back to readable text. Built for amateur radio, aviation enthusiasts, and anyone brushing up on dits and dahs.

Text → Morse

Letters, digits, and punctuation are mapped per ITU-T Morse. Spaces insert word separators (“/”).

Morse → Text

Use dots (·), dashes (−), or "." and "-" equivalents. Separate letters with spaces and words with “/”.

Timing refresher: dot = 1 unit, dash = 3 units, gap between dots/dashes = 1 unit, gap between letters = 3 units, gap between words = 7 units. Useful for keying practice.

Data Source & Methodology

Character encodings follow the International Morse Code standard (ITU-T Recommendation F.1). The translator accepts both typographic dots/dashes and ASCII “.” / “-” so you can paste from most code practice tools.

Supported Characters

We cover the standard ITU alphabet, numerals, and punctuation:

  • Letters A–Z, accented letters (Á, Ä, Å, É, Ñ, Ö, Ü) to their international Morse variants
  • Digits 0–9 (including procedural prosigns like “SK”, “SOS”)
  • Punctuation: period, comma, question, apostrophe, exclamation, slash, parentheses, colon, semicolon, equals, plus, hyphen, underscore, quotation marks, at-sign

Worked Example

Input: HELLO WORLD

  1. H → “····”
  2. E → “·”
  3. L → “·−··” (appears twice)
  4. O → “−−−”
  5. Word gap → “/”
  6. W → “·−−”
  7. R → “·−·”
  8. L → “·−··”
  9. D → “−··”

Result: ···· · ·−·· ·−·· −−− / ·−− ·−· ·−·· −··

Frequently Asked Questions

Does this output prosigns?

Yes—common procedural signals (e.g., “SOS”, “SK”, “AR”) are baked in. Use uppercase letters without spaces for prosigns.

Can I paste audio timing?

No. This tool works with symbolic dots/dashes. For audio to text you need a Morse decoder with DSP capabilities.

Is Farnsworth spacing supported?

Spacing guidelines are shown for reference; Farnsworth simply increases gaps. We keep the textual output standard.
