PDF to MIDI Converter
Free online PDF to MIDI tool — drop a file, get .mid
At launch this is a fully browser-based PDF to MIDI converter: drop a PDF, wait a few seconds, download .mid. No install, no signup for your first conversion. Paid plans unlock longer PDFs, batch processing, and priority queue. This page covers exactly what the tool does, file-size limits, pricing, and how it stacks up against commercial notation OMR — everything you need to decide if it fits your workflow.

Tool boundaries & limits
- Free tier: ≤10MB / ≤20 pages, 3 conversions/day, single file at a time.
- Pro tier: ≤25MB / ≤80 pages, 50 conversions/day, 5-file batch upload.

Tool-focused FAQ
Do I need to sign up?+
No. Anonymous visitors get 1 conversion/day. Sign in for 3/day. Paid plans raise the cap dramatically.
Do you keep my PDF?+
PDFs are deleted within 24 hours of conversion. Paid users can opt into account history (still one-click deletable).
How does it compare to ScanScore / SmartScore / PhotoScore?+
ScanScore is $99/year, SmartScore $349 one-time, PhotoScore $249. We start free with $9–$19/month tiers. We're targeting PhotoScore-level accuracy long-term and already win on web/cross-device convenience.
Is batch conversion supported?+
Pro supports 5 concurrent files. Studio adds folder uploads, API access, and conversion history.
Can I get MIDI and MusicXML at the same time?+
Yes. Every conversion produces both. Pick one or download both for editing in MuseScore, Sibelius, or Dorico.
Can I set the BPM before converting?+
Yes. If your PDF has no tempo markings we default to 100 BPM, and you can override at upload.
Do I get refunded if a conversion fails?+
Hard failures don't consume credits. Successful conversions that simply have low recognition quality do consume credits — the OMR did its work.
Is there an API?+
Studio includes 1,000 API calls/month. Use it inside a DAW plugin, an LMS, or a custom production pipeline.
