- 📻 Interactive Telegraph Keyer (Straight Key): Practice manual Morse signaling directly inside your browser using a digital telegraph key or your keyboard’s
Spacebar. - 💾 Export Morse Audio (WAV Download): Download synthesized Morse code audio tracks directly to your device for offline practice, ringtones, or educational training.
- 📖 Searchable Morse Code Reference Chart: Access a complete reference table containing letters (A-Z), numbers (0-9), special punctuation marks, and international prosigns.
💡 How to Use the Morse Code Translator
1. Translate Text to Morse Code
- Type or paste your message into the Text Input field.
- The translated Morse code (
. -) will appear immediately in the Morse Code output box. - Click the Play Sound button to listen to the audio signal or click Flash Light to view the optical signal.
2. Decode Morse Code to Text
- Type or paste dots (
.) and dashes (-) into the Morse Code box. Separate letters with a single space and words with a forward slash (/) or double space. - The translated English text will auto-populate in the Text box in real time.
3. Practice with the Digital Telegraph Key
- Click the Telegraph Key tab on the workspace.
- Hold down the Straight Key button or press and hold the
Spacebaron your keyboard. - Short presses register as dots ($\cdot$) and long holds register as dashes ($-$).

❓ Frequently Asked Questions (FAQ)
What is the timing rule for International Morse Code?
International Morse code timing is defined relative to the length of a single dot:
- A dot ($\cdot$) is $1\text{ unit}$ long.
- A dash ($-$) is $3\text{ units}$ long.
- The space between elements inside a letter is $1\text{ unit}$.
- The space between letters within a word is $3\text{ units}$.
- The space between words is $7\text{ units}$.
What is WPM and Farnsworth Timing?
WPM (Words Per Minute) measures overall transmission speed, historically standardized using the word “PARIS” ($50\text{ dot units}$). Farnsworth timing speeds up the sound of individual characters while inserting extra spacing between letters and words, making it easier for learners to recognize character sounds without feeling overwhelmed.
Are my messages sent to external servers?
No. All translation, Web Audio synthesis, and file generation processes run $100\%$ client-side inside your browser, guaranteeing total privacy and instant performance.
