PDF to MIDI Converter

Upload PDF, score images, MusicXML, or MXL and download a .mid file

PureMIDI's PDF to MIDI beta parses MusicXML/MXL directly. Clear digital PDFs use structure-aware score recognition, while scanned PDFs and score images become AI-recognized MIDI drafts that may need proofreading.

Upload score

Upload PDF, PNG, JPG, WebP, MusicXML, or MXL. MusicXML/MXL is parsed directly; clear digital PDFs use structure-aware recognition; scans and images may need proofreading.

Choose a score file to start

Score formats: PDF / PNG / JPG / WebP / MusicXML / MXL. Max 7.0 MB.

End-to-end workflow

  1. 01

    Use PDF, PNG/JPG/WebP, MusicXML, or MXL files up to about 7MB.

  2. 02

    Recognize notation

    MusicXML/MXL is parsed directly. Clear digital PDFs use structure-aware recognition; scans and images use AI score recognition.

  3. 03

    Review and export

    Download .mid directly, or proofread the draft in the editor and export MusicXML.

What people actually do with the converter

Producer reference imports

Convert a sheet music PDF you bought online, load the MIDI in Logic / FL Studio / Ableton, and audition the arrangement before deciding to cover it.

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

  • Current beta uploads are limited to about 7MB for stability.
  • Scanned PDFs and score images are best treated as editable drafts; dense polyphony, handwriting, TAB, numbered notation, and historical notation should be proofread in notation software after export.
  • MusicXML/MXL conversions use 1 credit; PDF/image score conversions use 4 credits. Hard failures release credits.
  • Credit packs are one-time purchases (no expiration), good for occasional or burst usage. See /pricing for current packs.

Current beta capabilities

Only features that are wired today, not roadmap promises.

  • Single-file upload for PDF, PNG, JPG, WebP, MusicXML, and MXL
  • Direct MusicXML/MXL to MIDI conversion
  • Structure-aware recognition for clear digital PDFs
  • AI notation recognition drafts for scanned PDFs and score images
  • Standard .mid download after successful conversion
  • 1 credit for MusicXML/MXL; 4 credits for PDF/image score conversion; hard failures release credits

When to proofread in notation software

Complex scores are not one-click perfect

Handwriting, TAB, numbered notation, dense polyphony, and elaborate ornaments still need review in MuseScore, Sibelius, or Dorico. PureMIDI's beta is meant to create a fast playable MIDI draft.

Core audio to MIDI paths

Choose the conversion path that matches your source. These pages separate general audio, compressed MP3 files, and YouTube/YT workflows so the upload and accuracy guidance stays specific.

AI audio to MIDI converter

Best default for WAV, M4A, FLAC, recordings, stems, and authorized audio exported from video.

MP3 to MIDI converter

Use the MP3-specific page when your source is compressed MP3 and you need bitrate or retry guidance.

YouTube to MIDI workflow

Preview a link, confirm rights, then upload audio you own or are licensed to use for MIDI conversion.

Already have a MIDI file?

If another score-recognition 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?+

PDF/image source files for successful conversions are deleted within 3 days. Failed-conversion sources may be retained for up to 14 days for recovery and support. Deleting the conversion requests immediate cleanup of its source and output files.

Is batch conversion supported?+

The beta handles one file at a time. Batch queues and one-click re-run come after score recognition quality is stable.

Can I get MIDI and MusicXML?+

Yes. Download MIDI directly, or open the score draft in the online editor, review pitch and rhythm, and export .musicxml.

Can I set the BPM before converting?+

The beta uses the score tempo when available and falls back to a default BPM. Manual BPM override is a next-step control.

Do I get refunded if a conversion fails?+

Hard failures don't consume credits. Successful conversions that produce an editable MIDI draft do consume credits, even when the result still needs proofreading.

Is there an API?+

Not yet. We are stabilizing the web converter and failure taxonomy before exposing a public webhook/API flow.
