Frequently asked questions

How do I convert MXL to MIDI?

Drop your .mxl file into the box above and click “Download MIDI”. The MXL (compressed MusicXML) file is unpacked and converted right in your browser.

How do I convert MusicXML to PDF?

Drop your .musicxml, .xml, or .mxl file above. ScorePort engraves the score and lets you download a print-ready PDF — no MuseScore, Finale, or Sibelius installation needed.

How do I open an MXL file without MuseScore?

MXL files are compressed MusicXML scores exported by apps like MuseScore, Finale, Sibelius, Dorico, and Flat.io. ScorePort opens them directly in your browser and shows the full sheet music instantly.

Is it really free? What's the catch?

Yes — free, no account, no watermark, unlimited files. If ScorePort saves you time, you can support development with a tip below.

Are my music files uploaded anywhere?

No. Unlike other online converters, ScorePort does all processing locally with WebAssembly. Your scores never leave your computer — you can even use it offline after the page loads.
