Morse Code Translator & Morse Audio Player

Morse code is a system of representing letters and numbers using a series of dots and dashes. It was developed in the 1830s and 1840s by Samuel Morse and Alfred Vail, and was first used for telegraphy, a method of communicating over long distances using electrical signals.

The code was later adapted for use in radio communications, and was also used during World War II by military personnel to communicate in the field. Today, while Morse code is no longer widely used for communication, it is still taught to pilots, amateur radio operators, and military personnel as a backup method of communication.

Type your message in the left panel and it is automatically converted to Morse code using dots (.), dashes (-), and slashes (/) to separate words. Letters within a word are separated by spaces.

You can also convert Morse code back to text by using the swap button to switch direction, then entering the Morse code on the left.

After converting text to Morse code, click the play button to hear the dots and dashes as audio tones. The playback uses your device's speakers or headphones. This is useful for learning Morse code timing or verifying your message sounds correct.

Yes, Morse code remains in active use in several areas. Amateur (ham) radio operators use it worldwide for long-distance communication, especially when voice signals are too weak to be understood. Aviation and maritime industries still recognize it for emergency signaling and navigational aids. Some military units maintain Morse proficiency as a backup communication method. It has also found a modern use as an accessibility tool, with some assistive devices allowing people with limited mobility to communicate by tapping dots and dashes. For other ways to encode text, try the binary code translator or the NATO alphabet translator.

Standard International Morse Code covers the 26 Latin letters (A-Z), the digits 0-9, and a set of common punctuation marks including period, comma, question mark, apostrophe, exclamation mark, slash, parentheses, ampersand, colon, semicolon, equals sign, plus sign, hyphen, quotation marks, and the at sign (@). Letters are case-insensitive since Morse has no distinction between uppercase and lowercase. Characters outside this set, such as accented letters or non-Latin scripts, do not have standard Morse equivalents and will be omitted from the translation.

A dot (.) represents a short signal and a dash (-) represents a long signal, typically three times the length of a dot. Each letter is formed by a unique combination of dots and dashes. Within this tool, individual letters are separated by a single space, and words are separated by a slash (/). In traditional Morse timing, the gap between letters is three dot-lengths and the gap between words is seven dot-lengths, which the audio playback on this page approximates when you press the play button.

There are two distinct Morse code standards. International Morse Code (ITU standard) is the version used worldwide today and is what this translator implements. It covers the 26 Latin letters, digits 0-9, and common punctuation using a consistent dot-and-dash system. American Morse Code (also called Railroad Morse or Landline Morse) was the original system developed by Samuel Morse himself and differs from International Morse in several characters. For example, the letter C is -. . in American Morse but -.-. in International Morse. American Morse Code was used by US telegraph operators until the mid-20th century and is now largely historical.

Correct Morse code transmission follows precise timing ratios. A dash is exactly 3 dot-lengths long. The gap between symbols within a letter is 1 dot-length. The gap between letters is 3 dot-lengths. The gap between words is 7 dot-lengths. At the standard amateur radio speed of 20 WPM (words per minute), a dot is approximately 60ms. This timing is approximated in the audio playback feature on this page.

SOS (... --- ...) is the international distress signal. Despite the popular misconception, SOS does not stand for "Save Our Souls" or "Save Our Ship." It was chosen because the pattern is distinctive and impossible to confuse with other signals: three dots, three dashes, three dots, sent as a continuous sequence with no letter spacing between them.

The ITU removed the mandatory Morse code requirement for amateur radio operators in 2003, and most countries including the UK (Ofcom) and USA (FCC) followed by 2007. The decision reflected that modern radio technology had made Morse unnecessary for emergency communications. Many amateur operators still learn it voluntarily, and Morse contacts remain common on HF bands.

Prosigns (procedural signals) are Morse code sequences sent without the standard letter spacing to convey operational instructions rather than text. Common prosigns include AR (end of message), SK (end of contact), and BT (paragraph break). This translator handles standard text only and does not generate prosigns. For other encoding methods, try the binary code translator, the NATO alphabet translator, or the Caesar cipher tool.
