Morse code calculator: encoder and decoder
Calculator encodes given text message into Morse codes or vice versa. You can also hear (beeps) and see (as sequence of light pulses) your Morse encoded message. For better readability currently played Morse character is higlighted (marked).

Some facts

  • Morse Code allows you to send a text message using a series of pulses of varying duration.
  • The message in the Morse code consists of:
    • short pulses - so-called dots,
    • long pulses - so-called dashes, it is assumed that one dash should last at least as much as three dots,
    • silence - no impulse for a time corresponding to three dots means the end of the character (letters, numbers etc.), a break lasting as many as seven dots marks the end of a word.
  • The Morse alphabet is a theoretical concept, i.e. it does not specify how to physically send impulses to receiver and vice versa. Depending on the possibilities and demand, impulses can be sent, e.g. using:
    • electrical impulses,
    • light pulses (e.g. during communication at sea),
    • gestures of the body (e.g. spread arms mean a dash, arms raised up a dot),
    • etc.
  • Morse code is case insensitive. This means that e.g. letters A and a will be coded in the same way.
  • The device that uses electrical impulses to send Morse code is telegraph.
  • A special sequence of impulses in the Morse code is the international SOS emergency signal, which means a call for help . The SOS signal consists of three short then three long pulses and then three short again. This makes it easy to remember and during repeated transmissions, it doesn't matter if we start with short or long pulses, e.g. as a result of a mistake.

How to use this tool

  • In the first field, enter or paste the text you want to encode or decode using Morse code.
  • Below you will see your message after conversion. For greater readability in the resulting message you can see three colors, whose meaning is as follows:
    • white - this is plain text after changing character-by-character,
    • green - if a fragment of the message was recognized as procedure sign (ang. prosign) e.g. international SOS signal, it will be marked in green. If you want to see the list and meaning of individual special symbols check our other calculator: Morse alphabet,
    • red - if we were unable to recognize a fragment of your message, it will be marked in red. These can be, for example, unrecognized letters in Morse code, unrecognized special codes, etc.
  • If you want to use a procedure signal in the input text, surround it with angle brace e.g. <SOS> means international SOS signal.
