PDF to MIDI Converter

AI PDF to MIDI tool — drop a file, get .mid · join the waitlist for free credits at launch

At launch this is a fully browser-based PDF to MIDI converter: drop a PDF, wait a few seconds, download .mid. No install, no subscription. New accounts get 2 free trial credits on signup; continue with one-time credit packs that don't expire. This page covers exactly what the tool does, file-size limits, pricing model, and how it stacks up against commercial notation OMR — everything you need to decide if it fits your workflow.

What people actually do with the converter

Producer reference imports

Cover and remix

Take a PDF score, convert to MIDI, re-orchestrate with new instruments and beats.

Piano students

Convert assigned études to MIDI and play along at half speed in your DAW or notation app.

Teacher grading

Convert a student's submission to MIDI as the answer key for fast playback grading.

Tool boundaries & limits

  • At launch the converter handles PDFs up to ~25MB / ~80 pages (limits will lift as performance is tuned).
  • Dense polyphony, handwritten scores, and historical notation should be proofread in notation software after export.
  • Each conversion uses 1 credit; new accounts get 2 free trial credits on signup, no subscription.
  • Credit packs are one-time purchases (no expiration), good for occasional or burst usage. See /pricing for current packs.

What the converter ships with at launch

Tool capabilities only — no theory. For how OMR works, see our PDF to MIDI guide.

  • Drag-and-drop and multi-file uploads (Pro and above)
  • MIDI and MusicXML in a single conversion run
  • Automatic unfolding of repeats, jumps, Da Capo, and voltas
  • Configurable export BPM, quantization level, and voice mapping
  • In-browser preview with switchable soundfonts (piano, ensemble, strings)
  • Conversion history with one-click re-download and delete (Pro+)
  • Studio API with HTTPS POST and webhook callbacks

Stopgap before launch

Need MIDI from PDF today?

Use any OMR tool you already have to get a draft MusicXML/MIDI, then validate the rhythm with our live Audio to MIDI tool by playing the score back. We'll let you import results once the dedicated converter ships.

Already have a MIDI file?

If another OMR tool, DAW, or notation app already gave you a .mid file, open it in PureMIDI's online editor for a quick cleanup pass.

Edit an existing MIDI file

Import .mid / .midi, play it back, inspect tracks, quantize, adjust velocity, and export again.

Tool-focused FAQ

Do I need to sign up?+

Yes — sign up to claim 2 free trial credits, valid 14 days. We don't offer anonymous free usage; the credit-based model keeps abuse and rights-risk under control.

Do you keep my PDF?+

PDFs are deleted within 24 hours of conversion. Account history is opt-in and one-click deletable.

Is batch conversion supported?+

At launch the queue handles multiple files with conversion history, one-click re-run, and one-click delete. Each file uses 1 credit.

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?+

We're rolling out a credit-billed API after launch with webhook callbacks. Drop it inside a DAW plugin, an LMS, or a custom production pipeline.
