Why This Site Was Built — Origin Story
OnlineMorseCode started from a simple frustration: every free Morse code tool I could find either had incorrect ITU timing ratios, no audio, or was broken on mobile. When researching Morse code for a personal project, I couldn't find a single translator that correctly implemented all five ITU timing rules — dot duration, dash duration, inter-element gap, inter-letter gap, and inter-word gap.
I built the first version over a weekend in 2024 with a single goal: correct ITU timing, real Web Audio API playback, and a clean mobile-first interface. After sharing it with a few ham radio forums and getting positive responses from CW operators who confirmed the timing accuracy, I expanded it into a full learning resource covering all aspects of Morse code.

What Makes Us Different
✅ Correct ITU Timing
I implement all five ITU timing ratios correctly. Most free tools get at least one wrong. My audio has been verified by CW operators who can hear timing errors.
🌍 18+ World Languages
Filipino, Hindi, Indonesian, Spanish, French, German, Persian, Korean, Japanese, Thai, Turkish, Kurdish, Greek, Chinese, Arabic, Hebrew, Cyrillic, and American Morse — with working bidirectional translators and audio for every character.
🔒 Privacy First
Everything runs in your browser. No text you translate is sent to my servers. Audio and image processing is entirely local. I collect no personal data.
🎓 Comprehensive Learning
A complete learning guide covering Koch method, Farnsworth timing, practice schedules, Q-codes, real-world uses, ham radio CW, and full FAQ.
Credentials & Verification Process
Content accuracy is my highest priority. Here is exactly how I verify the Morse code on this site:
Primary source: ITU-R M.1677-1
All character mappings are derived directly from the International Telecommunication Union Recommendation M.1677-1 — the official global Morse code standard updated in 2009.
Cross-referenced with ARRL
The American Radio Relay League Morse code tables are used to cross-check all Latin alphabet characters and timing specifications.
Audio verified by CW operators
Audio timing has been listened to and verified by licensed amateur radio operators experienced in CW (continuous wave) operation who can hear timing errors by ear.
Community error reporting
Users can report errors at waleedakram@onlinemorsecode.com. Confirmed errors are fixed within 24 hours and noted in our correction log.
Content Standards
I follow a strict content review process. Every page on this site that makes factual claims about Morse code (character mappings, timing, history, or usage) is reviewed against the ITU standard before publication. I do not publish AI-generated content without expert review. See my full Editorial Standards & Accuracy page for the complete process.
Contact & Transparency
I believe site owners should be reachable and transparent. If you have a question, have found an error, or want to discuss a partnership, I read every message:
