Text to Morse Code Translator

Type text above and it converts to Morse code instantly; switch to Morse to Text and paste in dots and dashes to read them back as plain text. The translator uses the real International Morse Code table, the same one used by amateur radio operators and maritime services, not a simplified approximation — so what you see here is the same code you'd need to actually key or read on the air.

How to Read the Output

A dot (.) represents a short signal and a dash (-) represents a signal three times as long. Within one converted word, individual letters are separated by a single space, and separate words are separated by a forward slash surrounded by spaces. If you're reading this off the page rather than listening to it, that spacing is standing in for the timing gaps a real Morse operator would send: one unit between the dots and dashes of a single letter, three units between letters, and seven units between words.

Why the Codes Are the Length They Are

The lengths aren't arbitrary — this is a frequency-optimized code, not a decorative one. Letters that turn up constantly in ordinary English writing got the shortest signals, and letters that are genuinely rare got the longest, most elaborate ones, on the logic that a working telegraph operator sends far more of the common letters in a day than the rare ones, so shaving fractions of a second off the common signals pays off over a long message. That's the reasoning behind E's single dot and T's single dash at one end of the scale, and Q, X and Z's longer, multi-part codes at the other. The specific, well-documented method Morse and his collaborator Alfred Vail reportedly used to figure out which letters were actually common enough to deserve the short codes is covered on the E reference page, where it's the more relevant story to tell in full.

What This Tool Is Good For

• Checking a Morse message you've received or half-remembered, without having to look up each letter one at a time.
• Preparing a message before sending it by hand, for practice or for a scouting/signalling badge.
• Building or solving a Morse-based puzzle, escape room clue, or code-cracking game.
• Quickly converting your own name or a short phrase to see how it looks and sounds in Morse.

Letters, Numbers and Punctuation, All Supported

Unlike a lot of quick single-purpose Morse boxes, this translator handles the full practical character set: all 26 letters, all 10 digits, and the common punctuation marks people actually type in a real message — periods, commas, question marks, apostrophes, hyphens, slashes and more, each using the exact code from the International Morse Code standard rather than an invented or simplified stand-in.

Listening, Flashing and Downloading the Result

Below the converter, this page also plays the current Morse code as real audible tones — built with the Web Audio API, using standard PARIS timing (a dash is exactly three times the length of a dot) at any speed from 5 to 40 words per minute, with optional Farnsworth spacing that keeps individual characters at full speed while stretching only the gaps between them. There's also a full-screen light/dark flash mode synced to the same timing, with a photosensitivity caution before it starts, and a one-click download of the current message as a real .wav file — the PCM audio is generated entirely in your browser, nothing is uploaded or rendered on a server.

Why a Separate Trainer Exists

Converting text is a lookup problem; learning to recognize Morse code by ear in real time is a completely different skill, closer to learning a musical rhythm than memorizing a chart. That's deliberately kept as its own tool, the Morse Trainer, rather than bolted awkwardly onto this converter — trying to do both jobs in one interface tends to make both of them worse.
