- Highest conversion accuracy
- Fast processing time
- Preserves all musical details
Scanned PDFs
Created from scanning physical sheet music or taking photos of printed scores.

How Melogen AI Converts PDF to MIDI
Our AI doesn't just "read" your PDF — it understands music.
Detect Musical Symbols
Our AI scans each page of your PDF and identifies notes, rests, clefs, time signatures, and other musical elements.
Analyze Musical Structure
The system maps out staff lines, measures, tempo markings, and how different parts relate to each other.
Reconstruct as MIDI
Timing, pitch, and duration are calculated and assembled into a clean, editable MIDI file.
What Accuracy Can You Expect?
We believe in honest expectations. Here's what our AI can deliver:
Clean Digital PDFs
Very high accuracy. Notes, rhythms, and dynamics are captured precisely.
High-Quality Scans
Good results. May need minor corrections for complex passages.
Old or Low-Res Scans
Usable output. Expect to review and edit some sections.
Handwritten Scores
Limited support. Best for simple, clearly written notation.
Our Honest Take
No converter is 100% perfect. We focus on giving you a solid starting point that saves hours of manual transcription.

PDF to MIDI Conversion FAQ
Answers to common questions about converting PDF sheet music to MIDI
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.
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.
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.
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).
Free users can upload PDFs up to 10MB. Premium users have a 50MB limit. Most sheet music PDFs are well under these limits.
Your files are processed securely and automatically deleted within 24 hours. We never store, share, or use your music for any other purpose.
Need Editable Notation Instead?
If you want to edit the score in notation software like MuseScore, Finale, or Sibelius, try our MusicXML converter.
