About MorseCodeApp
Free tools for translating, learning, and working with Morse code.
What this is
MorseCodeApp is a collection of free online tools for Morse code. The main one is the translator — type in English, get dots and dashes out. Or paste Morse and get English back. It also plays audio, flashes your screen, and lets you download the result as a WAV file.
Everything runs in your browser. Your text doesn't get sent to a server. There's no account to create, nothing to install.
Why it exists
Most Morse code tools online haven't changed much in years. They work, technically, but the interfaces feel like they were last updated when jQuery was still exciting. Some are buried under so many ads that you can barely find the input box.
We wanted something that actually looked and felt like a proper tool — fast, clean, and not trying to sell you a VPN on every click. That's about it. No grand manifesto.
What's here
Beyond the translator, there are tools for specific use cases:
- Morse Code Alphabet — quick reference chart for all letters, numbers, and punctuation
- SOS in Morse Code — play and learn the most recognized distress signal
- I Love You in Morse Code — popular for jewelry designs and tattoos
- Bracelet & Tattoo Designers — preview your message as a bead pattern or ink layout
More tools are in the works. The translator also supports multiple input modes — you can tap out Morse with your spacebar, or type dots and dashes directly in decode mode.
Audio that doesn't sound terrible
The translator generates audio using the Web Audio API. That means actual waveform synthesis, not pre-recorded clips stitched together. You can pick between sine, square, sawtooth, and triangle waves, adjust the speed (in words per minute), change the frequency, and download the result as a proper 44.1kHz WAV file.
Timing follows ITU-R M.1677-1 — the international standard. A dit is one unit, a dah is three, the gap between elements is one, between characters is three, and between words is seven.
Embeds
If you run a blog or educational site, you can embed the translator on your own pages. It loads in an iframe, respects the container width, and includes attribution back to MorseCodeApp. No API key needed.
Who's behind this
MorseCodeApp is built and maintained by a small group of enthusiasts under AppsYogi. We're not a Morse code academy or a ham radio club — just people who like building useful web tools and happened to land on Morse code.
If you want to get in touch, the contact page has an email. We read everything, even if replies sometimes take a day or two.
Open about what we track
We use Google Analytics to understand which tools get used the most and where visitors come from. We may show ads through Google AdSense to keep the lights on. Your translations and audio are never sent anywhere — all processing happens locally in your browser. More details on the privacy policy page.
