Morse Code Translator — Convert Text to Morse Code and Back Instantly
SOS in Morse is ••• −−− ••• — three dots, three dashes, three dots. This Morse code translator encodes any text to dots and dashes and decodes Morse back to letters instantly: "Hello" becomes ".... . .-.. .-.. ---". Ham radio operators use it for licensing exam practice, escape room designers embed it in puzzle clues, and history enthusiasts decode telegraph-era messages. Auto-detects direction — paste text or paste Morse. No signup needed.
What Is Morse Code Translator?
A Morse code converter translates text into Morse code dots and dashes — and decodes Morse code back to text. Morse code represents each letter and number as a unique pattern of short signals (dots, •) and long signals (dashes, −): "A" is •−, "B" is −•••, "SOS" is ••• −−− •••. Developed by Samuel Morse and Alfred Vail in the 1830s for electric telegraph communication, Morse code was the first practical long-distance text communication system and shaped the development of telecommunications.
Morse code remains in active use today: in amateur (ham) radio licensing exams, aviation navigation systems (VOR beacons broadcast their identifier in Morse), military communication training, accessibility tools for people with motor disabilities (Morse input allows communication with two switches), and popular culture references. It's also widely used as a puzzle element in escape rooms, ARGs (Alternate Reality Games), and educational coding activities.

Key Features
Uses the International Morse Code standardized by the ITU (International Telecommunication Union), codified in Recommendation M.1677-1. This is the global standard used in aviation (ICAO VOR beacon identifiers), amateur radio, and all modern Morse applications — distinct from the older American Morse used on 19th-century US telegraph lines.
Covers all 26 letters (A–Z), digits 0–9, and common punctuation (period, comma, question mark, apostrophe, slash) per the ITU standard. SOS (••• −−− •••) — adopted as the international distress signal at the 1906 Berlin Radiotelegraphic Conference — is a single continuous sequence, not three separate letters.
Paste plain text and get Morse output; paste a Morse string (dots, dashes, spaces) and get text. Direction detection is based on input character set — switching between encode and decode requires only changing the input.
No upload, no account. Morse conversion runs entirely in your browser.

Industry Standard
Morse code was developed by Samuel Morse and Alfred Vail in 1836–1837 for use with the electric telegraph. American Morse code was used on US telegraph lines; International Morse Code (ITU-R M.1677-1) became the global standard and remains the version used today. The ITU international distress signal SOS (••• −−− •••) was adopted in 1906. Amateur radio licensing in many countries (including the US until 2007) required Morse code proficiency. Today it is optional but remains tested in some national licensing systems.

Morse Code Translator Rules: How It Works
- →Each letter maps to a unique dot (.) and dash (-) pattern: A = .- , B = -... , S = ... , O = ---.
- →Letters in a word are separated by spaces; words are separated by " / " (space-slash-space).
- →Morse is case-insensitive — A and a produce the same code.
- →Numbers 0–9 are supported: 1 = .---- , 2 = ..--- , 5 = .....
- →Unsupported characters (emoji, accented letters, most symbols) are skipped or left unchanged.
- ×Use dots (.) for short signals and dashes (-) or (−) for long signals.
- ×Separate letters with a single space: ".-" space "..." = "AS".
- ×Separate words with " / " (space-slash-space) or three spaces.
- ×The tool auto-detects text vs Morse input — if input contains only dots, dashes, and spaces, it decodes.

Common Mistakes & Pro Tips
- !Confusing dots and dashes with different symbols — Morse code is conventionally written with "." (dot/dit) and "-" (dash/dah). Some representations use "•" and "−". When decoding, ensure your input uses a consistent representation. Spaces between letters and double spaces between words are critical — Morse without proper spacing is ambiguous.
- !Forgetting that numbers and punctuation have Morse representations — Morse code includes all ten digits (0-9) and common punctuation (period, comma, question mark). "5" is •••••, "0" is −−−−−. Not all symbols have standard Morse equivalents.
- !Confusing International Morse Code with American Morse Code — the original Morse telegraph system used by the US in the 19th century ("American Morse" or "Railroad Morse") had different codes for some letters and special characters. International Morse Code (ITU) was standardized later and is what all current ham radio, aviation, and emergency communication uses. American Morse is a historical artifact; if you're translating for any modern purpose, always use International Morse.
Frequently Asked Questions
Everything you need to know about Morse Code Translator
Who invented Morse code and why?
+
Samuel Morse (with significant contribution from Alfred Vail) developed Morse code in the 1830s alongside the electric telegraph. The telegraph could only transmit electrical pulses (on/off), so a code was needed to represent letters using patterns of short and long pulses. Morse designed the code with the most common letters getting the shortest codes: "E" is just • (one dot) since it's the most frequent English letter, following a frequency-optimization principle similar to Huffman coding.
What is the SOS signal and why is it used?
+
SOS (••• −−− •••) was adopted as the international distress signal in 1906 at the Berlin Radiotelegraphic Conference. It was chosen not for any specific acronym meaning (the "Save Our Souls" backronym came later) but because it's an easy-to-remember Morse pattern: three dots, three dashes, three dots — simple, distinctive, and hard to confuse with other signals. It replaced "CQD" (the earlier distress call) as the universal standard.
Is Morse code still used today?
+
Yes — in several active contexts: amateur radio operators still use Morse code (CW, Continuous Wave) for long-distance communication and contest operating; the FCC eliminated the Morse requirement for US ham licenses in 2007, but many operators still practice it. Aviation VOR beacons still transmit their 2-3 letter identifier in Morse. Some military branches maintain Morse training. Accessibility researchers use Morse as a two-switch text input method for people with severe motor disabilities.
What does "dit" and "dah" mean?
+
"Dit" (•) and "dah" (−) are the spoken names for Morse code elements, used when reading or practicing Morse aloud. "Dit" is short (approximately 1 unit of time); "dah" is long (3 units). Letters are separated by 1 unit of silence; words by 7 units. Operators speak sequences aloud as "dit-dah" (A), "dah-dit-dit-dit" (B), etc. This verbal representation makes it easier to internalize patterns through sound rather than reading symbols.
How long does it take to learn Morse code?
+
With consistent daily practice using the Koch method (starting with just 2 characters at high speed, adding more as you reach accuracy), most people can learn the full alphabet and numbers in 2-4 months. Reaching 5 wpm (words per minute) for a ham radio license typically takes 10-30 hours of practice. Achieving 13 wpm (the old extra class requirement) takes several months of daily practice. Conversational speed (20+ wpm) is a year or more of regular operation.
How does Morse code appear in aviation VOR beacons?
+
VOR (VHF Omnidirectional Range) beacons are ground-based navigation stations that broadcast on frequencies between 108 and 117.95 MHz. Each beacon continuously transmits its 2–3 letter identifier in Morse code at 1020 Hz, allowing pilots to positively identify the station they are receiving. For example, the San Francisco VOR transmits "SFO" in Morse: "... ..-. ---". Pilots are trained to identify VOR stations by their Morse identifier as a cross-check against frequency-based identification. This use of Morse in aviation remains active globally despite modern GPS navigation.
How is Morse code used as an accessibility text input method?
+
Google Gboard (Android keyboard) includes a Morse code input mode that allows typing any character using just two inputs — one for dot and one for dash. This was developed as part of Google's accessibility initiative to enable text communication for people with severe motor disabilities who can only activate two switches reliably (a sip-and-puff device, two buttons, or other adaptive switches). The input speed is slower than conventional typing but enables independent communication for people who would otherwise be unable to type. This is one of the active modern applications of Morse code alongside ham radio.
