PDF to MIDI
Turn PDF sheet music into a playable file.
Upload a PDF (or photo) of a printed part. The notes are read from the score and converted into a MIDI file you can listen to — plus MusicXML if you want to keep editing.

Questions
PDF to MIDI, explained.
How does the conversion work?
The score is read note by note — pitches, rhythm, key and time signature. From that, a MusicXML score is built, and the MIDI file is derived from it. That means the MIDI reflects the actual notation, not an audio guess.
MIDI or MusicXML — which one do I want?
MIDI is for listening and for DAWs: it stores pitches and timing. MusicXML is for editing and printing: it keeps slurs, dynamics and layout, and opens in MuseScore, Sibelius or Dorico. You get both here — same recognition, two exports.
Which PDFs work best?
Scanned or exported PDFs of printed, monophonic single-staff parts. We measure the staff line spacing before processing: below 10 pixels we reject the file instead of guessing — re-export at a higher resolution instead.
Is it really free?
The beta is free, no account needed. A fair subscription will follow once quality meets our own bar. Recognition is beta: please double-check any measures the ledger flags.
