About Morse Code Encoder

Overview

The Morse Code Encoder converts plain text into International Morse code using the standard letter and word spacing conventions. Each letter is separated by a single space, and words are separated by a slash ( / ), keeping the output clean and easy to read or share. An optional audio player turns the encoded output into Morse beeps using the Web Audio API, so you can hear the same rhythm you would on a telegraph key. Everything runs in your browser — your text never leaves your device.

FAQ

Which characters are supported?

A–Z, 0–9, and common punctuation: period, comma, question mark, apostrophe, exclamation, slash, parentheses, ampersand, colon, semicolon, equals, plus, minus, underscore, quote, dollar, and at sign. Letters are case-insensitive.

Why are some characters missing in the output?

Characters outside the supported set have no standard Morse representation. They are dropped from the output and listed in a warning so you can adjust the input.

Is the audio playback accurate to real Morse timing?

Yes. Dot length is derived from the WPM setting using the standard PARIS timing benchmark, and dashes, letter gaps, and word gaps follow the 1:3:7 dot ratio used by amateur radio operators.
