Morse Code Converter

What is Morse Code Converter?

Morse Code Converter translates text to International Morse Code sequences (dots and dashes) and decodes Morse back to text. It supports letters A-Z, digits 0-9, and common punctuation marks. The tool includes audio playback with adjustable speed (words per minute), visual dot/dash animation, and supports the Farnsworth timing method where character speed differs from inter-character spacing for learning.

Amateur radio enthusiasts practicing Morse code, educators teaching communication history, and developers adding creative encoding features to applications. The tool runs entirely in your browser — your data never leaves your device.

How to Use Morse Code Converter

1. Type text in the input field to encode it into Morse code dots and dashes
2. Or paste Morse code (dots and dashes separated by spaces) to decode it to text
3. Adjust the playback speed in words per minute using the speed slider
4. Click Play to hear the Morse code audio with proper timing
5. Copy the Morse code output for use in messages or documentation

Common Use Cases

• Learning Morse code by encoding and decoding practice messages with audio playback
• Encoding messages for amateur radio communication practice
• Decoding historical Morse code transcripts for educational or research purposes
• Adding Morse code Easter eggs or loading animations to web applications
• Teaching signal processing concepts with a tangible, audible encoding system

Pro Tips

• Standard Morse timing uses a 3:1 ratio — a dash is three times the duration of a dot, the space between dots/dashes within a letter is one dot duration, and the space between letters is three dot durations
• The SOS signal (...---...) has no letter spacing — it is sent as a single prosign, which is why it sounds distinctly different from S-O-S sent as separate letters
• Farnsworth timing sends individual characters at a faster speed but increases the gaps between them — this is scientifically proven to be more effective for learning than uniformly slow Morse
