Since .mscz is MuseScore’s format, its own software gives you the most reliable conversion.
Steps:
Note: MIDI doesn’t include sound samples—just note data (pitch, velocity, duration, tempo, etc.). It will export all parts/instruments.
If you do not have MuseScore installed and just need a quick conversion, you can use online tools. Note: You must upload your file to a third-party server, so avoid this for sensitive or copyrighted material.
Popular options:
If you are away from your main computer or only have a tablet, online converters seem tempting. Use them with caution.

Verdict: Only use online converters for simple, single-instrument scores (e.g., piano solo). Avoid for orchestral or complex works.
Congratulations, you have your .mid file. Now what? A raw export from MuseScore is often too "robotic." For professional use, import the MIDI into a DAW and apply these tweaks:
For power users, script writers, or batch conversions (e.g., converting 100 MSCZ files overnight), MuseScore includes a command-line interface. convert mscz to midi
Syntax (MuseScore 3/4):
musescore4 /path/to/your/file.mscz -o /path/to/output.mid
Or for batch conversion on Windows/Linux/macOS:
for file in *.mscz; do musescore4 "$file" -o "$file%.mscz.mid"; done
Why use this?
