Morse code translator: text to Morse and back

How to use the tool

1. Choose a direction and enter text or dots and dashes.
2. Use a space between encoded letters and / between words, then copy or download.
3. “Reverse conversion” uses the result as the new input and switches direction if it fits the 10,000-character limit. Converting back to text produces uppercase letters and normalizes spaces between words. For sequences of up to 24 letters, digits or punctuation marks, inspect the dots, dashes and pauses on the timeline. During playback the cursor follows the signal when animation is enabled.

Method and principles

The converter uses International Morse for A–Z and 0–9.

Accented Latin letters are simplified where possible; decoding returns uppercase letters.

Method and limits

Up to 10,000 input characters. Also supports . , ? ' ! / ( ) & : ; = + - _ double quotes and @. Japanese or Korean Morse alphabets, emoji and procedural signals are not supported.

Inputs and results are processed in your browser and are not sent to the server. Aggregate statistics, when enabled, record only the tool and outcome, without the content.

Example

SOS 123 becomes ... --- ... / .---- ..--- ...--. Decoding that sequence gives SOS 123.
