Free online CAPX to MSCZ converter

Capella scores use CAPX, while MuseScore projects use MSCZ; converting lets you continue editing a score in MuseScore or share it with someone who works in that format. The conversion transfers notation data, not a rendered audio recording.

What the CAPX format is

CAPX is a Capella music-notation score format. Capella notation software creates it, and it stores editable score information such as notes, rhythms, and layout rather than audio.

What the MSCZ format is

MSCZ is MuseScore’s compressed native score format. It keeps a MuseScore score editable while using less space than the uncompressed MSCX format, and is suitable for sharing or archiving MuseScore projects.

How to convert CAPX to MSCZ

Online on 101convert.com

1. Upload the CAPX file on the converter page; the page shows the per-file size limit.
2. Select MSCZ as the output format and start the conversion. The conversion runs on the site’s server with MuseScore.
3. Download the converted MSCZ file. The converter supports batch conversion if you have several scores.

Offline with desktop software

In MuseScore desktop for Windows, macOS, or Linux, open the CAPX file with File → Open. After checking the imported score, use File → Save As and choose MSCZ as the file type. MuseScore can import Capella CAPX scores and save them in its native format.

Quality and compatibility

Importing between notation programs can change page layout, spacing, or other program-specific formatting. Review the saved score in MuseScore, especially if it contains unusual notation or detailed layout adjustments. MSCZ is an editable score file, not a substitute for audio export.
