Free online MUS to MUSICXML converter

A Finale score saved as .mus may need conversion when another notation program accepts MusicXML but cannot open Finale’s native file. MusicXML also makes scores easier to exchange between notation applications.

What the MUS format is

.mus is Finale’s proprietary notation-file format, used for editable music scores created in MakeMusic Finale. It is not an audio file. Legacy Finale documents commonly use .mus; later versions use .musx. You may encounter these files in older score archives or when receiving a Finale project.

What the MUSICXML format is

MusicXML is a score-exchange format supported by many notation programs, including MuseScore and Finale. It represents musical notation—such as notes, rhythms, measures, and instruments—in a form that different applications can import. Use it to move an editable score between programs or preserve it in a broadly supported notation format.

How to convert MUS to MUSICXML

Online on 101convert.com

1. Upload the .mus file to the converter on this page.
2. Run the conversion to MusicXML. The converter runs on our server with denigma; you can add several files for batch conversion. The page shows the per-file size limit.
3. Download the converted MusicXML file.

Offline with desktop software

Finale can open its native .mus files and export MusicXML. Open the score in a compatible Finale installation, then choose File → Export → MusicXML and save the exported file. Finale is commercial desktop software for Windows and macOS.

MuseScore is free and open source, but it does not directly import Finale’s native .mus format. It can open MusicXML after the file has been exported from Finale; use File → Open in MuseScore to check the result.

Conversion quality and limitations

MusicXML transfers musical notation, but page layout, fonts, spacing, playback settings, and some Finale-specific markings may not match exactly in the receiving program. Review the imported score for missing or altered expressions, articulations, and formatting.
