Morse Code Video
Type a message and record a short video where a light pulses in time with the Morse tone and the current letter flashes on screen. The recording captures the sound too, so the downloaded clip plays the code aloud.

A shareable signal clip
This tool draws an animation to a canvas, generates the matching CW tone with the Web Audio API, and records both together using your browser's built-in MediaRecorder. The result is a self-contained video file you can post, message, or drop into a slideshow. Everything happens locally on your device.
Recordings are saved as MP4 where the browser can record it (Safari and recent Chrome and Edge), since MP4 plays on any phone and posts to any app. Other browsers save WebM, and the page says which you will get before you record. If your browser cannot record video, you can still download the message as a WAV audio file.
How it works
- Enter your message and choose the speed (WPM) and tone pitch.
- Press Record. The full message plays once while it captures.
- When it finishes, preview the clip and download it.
- Keep the tab focused while recording for the smoothest result.
