Morse converter

Morse converter is a free tool that converts ordinary text to Morse code and Morse code back to text.

What do the dots, dashes, and spaces mean?

Dots and dashes form variable-length patterns that represent letters, numbers, and some punctuation marks. In International Morse code, a dot is one time unit and a dash is three units. Timing or written separators mark the boundaries between symbols, letters, and words.

Letter boundaries matter because several codes begin with the same pattern. A single dot represents E, while two dots represent I. In written Morse, spaces commonly separate letters and a slash commonly separates words. Radio operators use pauses instead of visible separators.

Which input field should I use?

Use To morse for ordinary text and To text for a sequence of dots and dashes. The converted value is returned in the Morse result field.

  • Choose To morse when preparing a message for a radio exercise, buzzer, LED, or programming project.
  • Choose To text when checking a received or copied Morse sequence.
  • Check separators carefully before translating Morse back to text. Missing letter boundaries can make a sequence ambiguous.

The conversion runs on the server. Your input travels to the server over HTTPS and is not stored.

Worked notation and sample values

For one small example, RADIO becomes ".-. .- -.. .. ---". Each group corresponds to one letter, and the spaces preserve the letter boundaries.

A common hand-conversion mistake is counting dots and dashes correctly but placing the separator in the wrong position. Another is reversing a pattern, such as reading A, .-, as N, -.

Morse code in software, networks, circuits, classrooms, and radio

Morse code remains useful for radio communication, technical demonstrations, and projects that represent information with two signal states. Amateur radio operators use continuous-wave communication, commonly called CW, while some radio navigation aids and beacons transmit identifiers in Morse.

Programmers may write Morse encoders to practice lookup tables, input parsing, or timing logic. Electronics projects can produce Morse with an LED, speaker, relay, or microcontroller. Networking courses sometimes use it to explain framing and symbol boundaries, although Morse is not an internet transport format. In education, it provides a compact example of variable-length encoding and signal timing.

For positional number systems rather than signal notation, a Decimal converter or Octal converter is a more appropriate choice.

What causes ambiguous or incorrect Morse input?

Missing separators are the main cause of ambiguous Morse input. Because character codes have different lengths, one uninterrupted sequence can often be divided into letters in several ways.

Punctuation also needs care. International Morse defines codes for several common punctuation marks, but it does not provide a standard representation for every typographic symbol, emoji, or writing system. Accented letters have extensions in some Morse conventions, and support can differ between implementations. If a character must survive conversion exactly, verify that it has an agreed Morse representation first.

Morse code is also not encryption. Anyone who knows the notation can decode it, so do not use it to protect passwords, account details, private messages, or other sensitive information.

Morse code questions people often ask

Can Morse code represent accented letters?

Some national and extended Morse alphabets include accented letters, but the mappings are not as universal as basic International Morse. When exchanging a message with another system or operator, agree on the extension before using those characters.

Can I convert emoji or other Unicode symbols to Morse?

No standard International Morse patterns exist for emoji and most Unicode symbols. You would need to replace them with descriptive words or define a custom mapping, which would no longer be standard Morse code.

What happens if there are no spaces between Morse letters?

The message may have more than one possible reading. Add clear boundaries between characters before converting, using the separator convention expected by the receiving system.

Is Morse code binary?

Morse uses two signal types, dots and dashes, but it is not a fixed-width binary number system. It also depends on timing or separators, so treating dots as 0 and dashes as 1 does not preserve a message unless letter and word boundaries are recorded too.
