Free, private browser tool converting MP3 audio to editable MIDI files instantly—no uploads needed.
MP3 to MIDI Converter is a free, private, browser-based AI tool that transcribes MP3 audio into editable MIDI notes. Everything runs 100% on-device in your browser - no audio is uploaded to any server, no signup or account is required, and no data ever leaves your machine. Simply drop in an MP3 or other audio file, and the built-in transcription engine automatically detects the melody, harmony, and rhythm, converting them into clean, standard MIDI notes you can play back instantly. After transcription, you can preview the result right in the player, fine-tune individual notes, adjust tempo and key if needed, and export everything as a standard .mid file that works with any DAW (FL Studio, Ableton, Cubase, Logic), notation software like MuseScore or Sibelius, or directly on supported keyboards and MIDI hardware. It is ideal for musicians who want to learn a song by ear, producers who want to quickly get a song into a project for remixing or arranging, music students practicing transcription, and content creators converting audio into playable MIDI. Lightweight, fast, and respectful of your privacy, MP3 to MIDI Converter makes turning audio into MIDI effortless.
