Questions

Is it free?

Yes, and nothing is uploaded: the cleaning happens in your browser.

Can it rename the files on my computer?

A web page can't rename files on your computer. The MatrixX app can: tell it the names you want and it renames the real files, then shows you what it changed.

Why clean file names at all?

Short, lowercase names without spaces or odd characters sort properly, work in links and uploads, and are easier to find later.
