Did you know the SOS distress call was chosen because it is easy to send and hear? The Morse Code Encoder turns plain English text and numbers into standard International Morse Code dots and dashes.
It is built for radio hobbyists, students, teachers, and anyone making a Morse puzzle. You type into one box, and the dot and dash output appears right away.

What the Encoder Does
The tool converts text into International Morse Code inside your browser. It reads one input box and writes one output box, with a button to copy the result.
- Plain Text Input: the box where you type or paste your message. It starts with the sample SOS Hello World 123.
- Morse Output: a read only box that shows dots and dashes as you type.
- Translate to Morse Code: a button that runs the same conversion on demand.
- Copy: a button that copies the output and then shows a short status.
Three counters sit at the top of the tool. They show the Characters count, the Words count, and the Unsupported count.
How to Use It, Step by Step
- Type or paste your message into Plain Text Input. The output updates as you type.
- Use letters A to Z, the digits 0 to 9, and supported marks like period, comma, and question mark.
- Read the dots and dashes in the Morse Output box below.
- Press Translate to Morse Code if you want to force a fresh conversion.
- Press Copy to save the output. The button then shows Copied or Copy failed.
How the Encoding Works
The tool does not use a math formula. It uses a lookup table based on the International Morse Code standard. Each letter, digit, and supported symbol maps to one fixed pattern.
First the tool trims your text and collapses any extra spaces. Then it makes the text uppercase and checks each character against the table.
Your Text→Clean Spaces→Make Uppercase→Look Up Each Character→Dots and Dashes
A space between words becomes a slash with a space on each side. That slash marks the word break, so a reader knows where one word ends.
Worked Example
Keep the sample text SOS Hello World 123 in the box. The tool reads it as SOS HELLO WORLD 123 in uppercase.
| Part | Characters | Morse Output |
|---|
| Word 1 | S O S | ... --- ... |
| Word 2 | H E L L O | .... . .-.. .-.. --- |
| Word 3 | W O R L D | .-- --- .-. .-.. -.. |
| Word 4 | 1 2 3 | .---- ..--- ...-- |
The full output joins these with a slash between each word. It reads: ... --- ... / .... . .-.. .-.. --- / .-- --- .-. .-.. -.. / .---- ..--- ...--
For this sample the counters read 16 Characters, 4 Words, and 0 Unsupported. Spaces are not counted as characters.
How to Read the Output
A dot is a short signal and a dash is a long signal. Together they form one character. Read each group between spaces as a single letter or digit.
One space separates letters inside a word. A slash with a space on each side separates whole words. That spacing lets someone read your message back correctly.
Supported Characters and Spacing
The table covers all 26 letters and the digits 0 through 9. It also covers common marks like the period, comma, question mark, slash, and hyphen.
It supports more punctuation too, such as the at sign, colon, plus sign, and dollar sign. Each of these follows a standard Morse pattern.
Any character not in the table is shown as a [?] placeholder. The tool does not pass unknown symbols through as themselves.
A short message then names the characters it could not translate. The Unsupported counter shows how many were replaced.
If you need the reverse direction, the Morse code decoder turns dots and dashes back into text. For another letter puzzle, try the ROT13 letter shift encoder.
Reading the Live Counters
The three counters react to your input as you type. Characters counts every letter, digit, and mark, but not the spaces. Words counts each group of letters split by a space.
Unsupported counts the characters shown as a [?] placeholder. A value above zero means part of your text is not real Morse. Clear or swap those characters before you send a signal.
Limitations and Assumptions
- This is a text conversion tool, not sound. It does not play beeps or control timing.
- Letter case is ignored, since the text is made uppercase first. Morse has no separate capitals.
- Unknown characters become a [?] placeholder, so they are flagged rather than hidden.
- The output uses a single space between letters and a slash between words. You cannot change that spacing.
- Extra spaces, tabs, and line breaks collapse into one word break. Leading and trailing spaces are removed.
- The input box accepts up to 5,000 characters, which keeps very large pastes manageable.
For other ways to turn text into code, the text to binary encoder shows ones and zeros. The ASCII table viewer lists the number for each character. You can find more utilities in the developer tools hub.
FAQs About the Morse Code Encoder
What Standard Does This Encoder Use?
It uses the International Morse Code table, the version used around the world. This differs from the older American Morse once used on landline telegraphs.
Is My Text Sent to a Server?
No. The conversion runs in your browser with a built in table. Your message is not uploaded or stored by the tool.
Can I Use It on a Phone or Tablet?
Yes. The tool works in any modern browser on a phone, tablet, or computer. You type in the same box and read the same output.
Does It Encode Emoji or Accented Letters?
No. Emoji and accented letters are not part of International Morse Code. The encoder treats them as unsupported, so they do not form valid dots and dashes.
Is Morse Code Still Used Today?
Yes. Amateur radio operators still use it, and it remains handy for simple light or sound signals. Many people also learn it as a hobby or skill.
