Music to MIDI Converter — Free, No Signup

Yes, converting is free in your browser. New visitors get 1 free download, and verified users get an extra free download. To keep downloading afterward, you can buy a permanent credit pack (no subscription).

The converter supports MP3, WAV, M4A, FLAC, OGG, WebM, MP4, MOV, and AAC files up to 5 minutes. So whether you have a compressed MP3, a lossless FLAC, or the audio from a video, you can turn any song into MIDI.

Upload your music file to the converter, select the preset that matches the audio — Piano, Voice, Guitar, Bass, Solo, or Full Song — and the AI transcribes the notes. Preview the result in the piano roll editor, then download your MIDI file.

Accuracy depends on the clarity of the music and the preset you pick. Clear, isolated instruments and simple melodies transcribe the most accurately. Our AI model (Spotify Basic Pitch) detects note onsets, pitch, and velocity with high precision, and the built-in piano roll editor lets you fine-tune the output.

No. All processing happens locally in your browser using a lightweight AI model. Your music never leaves your device, making the conversion completely private and secure.

Yes. The built-in piano roll editor lets you move, resize, join, or delete notes with undo/redo support. You can also adjust sensitivity, minimum note length, and pitch bends to fine-tune the transcription.

Music is recorded audio — a file that stores sound waves. MIDI is a set of musical instructions: which notes were played, when, and how hard. Converting music to MIDI transcribes those notes so you can edit, transpose, or play them back through any virtual instrument.

Yes. The Full Song preset is designed for polyphonic, multi-instrument music and produces a full MIDI transcription. For the best results on a single instrument, choose the matching preset like Piano, Guitar, or Bass.

The converter includes presets for Piano, Voice, Guitar, Bass, Solo (monophonic), and Full Song (polyphonic). Choose the preset that matches the music in your file for the most accurate transcription.

Our converter works with the music files you upload. To convert a streaming song, you first need the audio file. You can also use our YouTube to MIDI tool to extract audio from a link and convert it to MIDI.

Select the Piano preset before uploading your file, then upload the song. The converter transcribes the audio into piano notes, which you can edit in the piano roll and download as MIDI. Piano and vocal audio give the cleanest results.

Yes. All conversion happens in your browser, so there are no server costs — which means the tool stays completely free, with no account, no watermarks, and no hidden fees. You can convert as many songs as you like, as long as each is within the duration limit.

Drag and drop any music file into the converter, pick the matching preset, and let the AI transcribe it. Within seconds you get an editable MIDI file with a piano roll preview, ready to download or edit.

Yes. Our tool is 100% free and requires no signup or account. It runs entirely in your browser using on-device AI, so your music never leaves your device, and there are no usage limits on how often you can convert.
