Convert Any Song to MIDI in Your Browser
A song is recorded audio — a stream of sound waves. A MIDI file is musical data: which notes to play, for how long, and how loud. Converting a song to MIDI takes that audio and turns it into clean, editable notes you can use in any DAW, notation app, or sequencer. Because the transcription runs entirely on your device, it works whether you upload a single-instrument demo, an instrumental loop, or a finished record.
Unlike static note-by-note transcription services, this tool uses an on-device AI model that listens the way a musician does. It separates the melody you hear and writes it down as MIDI. The engine is the open-source Spotify Basic Pitch model. With presets tuned for piano, voice, guitar, bass, solo, and full songs, you get an accurate starting point for any track.

Multiple Presets
Piano, Voice, Guitar, Bass, Solo, and Full Song presets match your track.
Single Instrument or Instrumental
If your song is one clean instrument — a piano ballad, a guitar riff, a violin solo, or a pure instrumental — this converter is the most accurate option. With a single melody to track, the AI captures the notes, timing, and pitch bends with very high fidelity.
Studio Mix or Full Band
For a dense full-band mix, switch to the Full Song preset. It transcribes the dominant melody and structure so you get an editable score of the song. You can then clean up chords and layered parts in the piano-roll editor.
Song to MIDI FAQs
Can I convert a song to MIDI for free?
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).
What song formats are supported for MIDI conversion?
We support MP3, WAV, M4A, AAC, FLAC, OGG, WebM, MP4, and MOV. Whether your song is a downloaded MP3, a WAV export, or the audio from a music video, the browser can decode it locally.
How do I convert a song into a MIDI file?
Upload your song, pick the preset that matches the instrument (Piano, Voice, Guitar, Bass, Solo, or Full Song), let the AI transcribe the notes, then preview and download the MIDI. It takes a few seconds and stays in your browser.
Can I convert a single-instrument song or instrumental to MIDI?
Absolutely. Single-instrument songs and instrumentals are the best case for this type of conversion. A clean piano, guitar, violin, or solo vocal line transcribes with high accuracy because the AI isolates one clear melody at a time.
How accurate is the song to MIDI conversion?
Accuracy depends on how clean the source is. A single instrument or pure instrumental converts very accurately. Dense, multi-instrument mixes with heavy reverb are harder — you can clean up any notes in the built-in piano-roll editor after conversion.
Is my song uploaded to a server?
No. All processing happens locally in your browser using the on-device AI model. Your song is never uploaded, so your audio stays completely private.
Can I edit the MIDI after converting a song?
Yes. The built-in piano-roll editor lets you drag notes, change pitch and length, adjust timing, and preview your edits before downloading the final MIDI file.
What is the difference between a song and a MIDI file?
A song is recorded audio (sound waves). A MIDI file is a set of instructions — which notes to play, how long, and how loud. Converting the audio to MIDI turns it into editable musical data you can use in any DAW or notation software.
Can I convert a full multi-instrument song to MIDI?
Yes. Use the Full Song preset for a complete mix. It transcribes the dominant melody and structure across instruments. For the cleanest result, try to isolate a single stem or use a track with a clear lead part.
Which preset should I use for my song?
For a piano piece use Piano, for a vocal use Voice, for guitar use Guitar, and for a full mix choose Full Song. Each preset tunes the AI sensitivity to match the instrument in your song.
Can I convert a Spotify or YouTube song to MIDI?
You can convert any song you have as a file. For a YouTube song, use our dedicated YouTube to MIDI tool to extract the audio first, then convert it here. For Spotify, export or record the track to a file first.
Is there an AI song to MIDI converter with no signup?
Yes — this is an AI song to MIDI converter that needs no account. It runs entirely in your browser, so there is nothing to sign up for and no data to hand over.
How do I turn a piano song into a MIDI file?
A piano song is ideal for MIDI conversion. Upload the recording, select the Piano preset, and the AI transcribes each key press into editable MIDI notes you can download instantly.
How do I convert a song to MIDI online for free?
Open this page, drop in your song file, choose a preset, and the converter does the rest entirely in your browser. It is the quickest free way to turn song into MIDI online.
