What This Tool Does
This Morse code translator maps A–Z, digits, and common punctuation to International Morse patterns and reverses the process for decoding. It runs entirely in your browser—handy for ham radio practice, escape-room puzzles, scouting activities, and LED blink projects without installing desktop software.
Character Support
Letters A–Z
All Latin letters encode and decode using the standard International Morse alphabet.
Numbers 0–9
Digits use five-element patterns (for example, 1 → .----, 0 → -----).
Common punctuation
Period, comma, question mark, exclamation, quotes, parentheses, and symbols like @ and & are supported.
Word separator: /
A slash marks a word boundary in text output. When encoding, spaces between words become / .
Unsupported characters
Emoji, accented letters, and symbols outside the International Morse set are ignored when encoding. A friendly notice appears in the status bar.
Common Uses
Amateur radio practice and license exam prep
Emergency distress signals such as SOS
Escape room and puzzle hunt clues
Treasure hunts and geocaching riddles
Scouting badges and outdoor education
Classroom history and telegraph lessons
LED blink and Arduino Morse projects
Historical telegraph excerpt decoding
Morse Code Timing Rules
When sending Morse by sound or light, timing defines readability. These ratios are the standard reference for manual keying.
Dot = 1 unit
The shortest signal element—a quick tone or flash.
Dash = 3 units
A dash lasts three times as long as a dot.
Space between parts of same letter = 1 unit
Gap between dots and dashes inside one character (for example, in B = -...).
Space between letters = 3 units
Pause between completed letters in a word.
Space between words = 7 units
Longer pause between words; in text form this is often written as /.

Notes & Limitations
All translation runs locally in your browser. This tool outputs text patterns only—it does not play audible tones. Prosigns and national variants beyond International Morse are not included.
Frequently Asked Questions
What is SOS in Morse code?
SOS is ... --- ...—three letters, not an acronym. It became the international distress signal because the pattern is easy to recognize even in poor conditions.
How are spaces written in Morse code?
In text form, put a single space between letters and / (or a double space) between words. When keying by sound, a longer pause marks a word boundary.
Does this support numbers?
Yes. Digits 0–9 each have a unique five-element Morse pattern, such as 1 → .---- and 0 → -----.
Does this support punctuation?
Yes. Common punctuation—including period, comma, question mark, exclamation, and parentheses—is included in the International Morse table used by this tool.
What does / mean in Morse code?
A slash marks a word separator in written Morse. It corresponds to the longer pause between words when sending by radio or light.
Can I decode Morse back to text?
Yes. Select Morse to Text, paste dot-dash patterns with spaces between letters, and the plain-text translation appears instantly. Use Swap ↔ to reverse direction.
Is Morse code the same in every country?
International Morse is standardized for Latin letters and numerals worldwide. Some historical national telegraph codes differed, but modern amateur radio and maritime practice use the same ITU-style alphabet shown here.
Is my message uploaded when translating?
No. Translation runs entirely in your browser—nothing is sent to a server.
