Minimal LibreOffice installation for file format conversion

I am going to use LibreOffice for command line file format conversion only, for example:

soffice --headless --convert-to doc --outdir D:\output D:\input\filename.docx

The minimal LibreOffice installation is about 350 MB large. How could I install only the files that I really need?

You can’t. LO is a unified application with much shared components, especially since v4.2. Refer this answer.

Thank you!
