Morse Code Translator

What is the Morse Code Translator?

The Morse Code Translator is a free online tool that converts ordinary text into International Morse Code and decodes Morse code back into readable text, both directions on one screen. Beyond showing the dots and dashes, it can play your message out loud as a sequence of beeps with a synchronized flashing light, so you can hear and see exactly how the signal sounds at any speed.

How to use it

1. Type or paste your words into the Text box. The Morse code appears instantly in the box beneath it.
2. To go the other way, paste dots and dashes into the Morse box — separate letters with a single space and words with a slash — and the plain text appears live.
3. Press Play to hear the message as beeps while a panel flashes in time with each signal.
4. Drag the speed slider to set the words per minute, from a slow learning pace to a fast operator pace.
5. Tap Copy to grab the result. One glance, done — no sign-up and nothing to install.

The method behind it

Each letter and digit maps to a fixed pattern of short signals (dots) and long signals (dashes), defined by the International Telecommunication Union standard. Encoding looks up every character in that table and joins the patterns with a single space between letters and a slash between words. Decoding reverses the lookup: each space-separated group of dots and dashes is matched back to its character. The audio player follows the classic timing where a dot is one unit, a dash is three units, the gap inside a letter is one unit, the gap between letters is three units, and the gap between words is seven units. The dot length comes from the PARIS standard, where the duration in milliseconds equals 1200 divided by the words per minute, so 20 WPM produces a 60-millisecond dot.

Examples

• Text SOS becomes Morse ... --- ..., the famous distress call.
• Text HELLO WORLD becomes .... . .-.. .-.. --- / .-- --- .-. .-.. -...
• Morse -- --- .-. ... . decodes back to the text MORSE.

Common use cases

• Students and teachers learning or demonstrating how Morse code works.
• Amateur (ham) radio newcomers practicing sending and copying messages.
• Scouts and cadets studying signaling for badges and field exercises.
• Puzzle hunts, escape rooms, and geocaching where a message is hidden in dots and dashes.
• Hobbyists adding a Morse beep or flash effect to a project and checking the timing.

Why use this one

Most pages that rank for this query only show static dots and dashes, and many split text-to-Morse and Morse-to-text into two separate one-way pages. This tool keeps both directions on a single screen, adds audible beep playback with a synced visual flash, and lets you adjust the speed in words per minute. Everything runs in your browser, so your text never leaves the page and there is no account to create.
