Illustrated workflow · PDF to MIDI: upload, convert and download

Upload Your PDF Score

Drag and drop your PDF file or click to browse. We'll handle the rest.

YOUR WORKFLOW

From your file to your next step.

  1. Detect Musical Symbols

    Our AI scans each page of your PDF and identifies notes, rests, clefs, time signatures, and other musical elements.

  2. Analyze Musical Structure

    The system maps out staff lines, measures, tempo markings, and how different parts relate to each other.

  3. Reconstruct as MIDI

    Timing, pitch, and duration are calculated and assembled into a clean, editable MIDI file.

This process typically takes 10-30 seconds depending on the complexity of your score.

Not sure which type you have? Digital PDFs usually have selectable text, while scanned PDFs look like photos.

What Accuracy Can You Expect?

We believe in honest expectations. Here's what our AI can deliver:

Clean Digital PDFs95%+

Very high accuracy. Notes, rhythms, and dynamics are captured precisely.

High-Quality Scans85-95%

Good results. May need minor corrections for complex passages.

Old or Low-Res Scans70-85%

Usable output. Expect to review and edit some sections.

PDF to MIDI Conversion FAQ

Answers to common questions about converting PDF sheet music to MIDI

What types of PDF files can I convert?

You can convert both digital PDFs (exported from notation software) and scanned PDFs (from physical sheet music). Digital PDFs typically yield better results, but our AI handles both types effectively.

Can I convert multi-page PDF scores?

Yes! Our converter processes all pages in your PDF and combines them into a single MIDI file. Each page is analyzed sequentially to maintain the correct musical flow.

How can I get the best conversion results?

For scanned PDFs: use high resolution (300 DPI+), ensure good lighting, and avoid skewed or cropped pages. For digital PDFs: export directly from your notation software without compression.

Can I edit the MIDI after conversion?

Absolutely. The output is a standard MIDI file that works with any DAW (FL Studio, Ableton, Logic Pro, etc.) or notation software (MuseScore, Finale, Sibelius).

Is there a file size limit?

Free users can upload PDFs up to 10MB. Premium users have a 50MB limit. Most sheet music PDFs are well under these limits.

What happens to my uploaded PDF?

Your files are processed securely and automatically deleted within 24 hours. We never store, share, or use your music for any other purpose.

A place in your music workflow.

I start with a short piano score, check the converted notes, then use the MIDI in my teaching software to put together a practice exercise.

Maya ChenPiano teacherLesson preparation

I keep the score beside the piano roll while I review the MIDI. Once the notes are right, I can try different voicings in my usual music software.

Elena RuizArrangerArranging

Hearing a passage alongside the page helps me work out what I am reading. I go back to the original score whenever a note sounds unexpected.

Sofia MartinsStudentScore study

For a new vocal part, I bring the converted notes into my music software and make a rehearsal reference. I check it against the score before singing along.

Amina DialloVocalistVocal rehearsal

Getting a printed melody into my DAW gives me something to arrange around. I choose the instrument sound there and work on the timing before adding other parts.

Leo ParkProducerProduction

Some of my ideas begin on manuscript paper. Moving a legible score into MIDI gives me another way to develop the melody in a session.

Noah KimSongwriterSongwriting

I use the MIDI in my own player while learning melodies from standard notation. Hearing the line gives me a reference as I work out the fingering on guitar.

Jonah AdeyemiGuitaristGuitar practice

A short score is enough for the listening exercises I prepare. I review the conversion first, then make the lesson material in my notation editor.
