What does flattening do?

It bakes interactive form fields and their values into the page so the content stays visible but becomes read-only.

Will the values stay visible?

Yes — the filled-in values remain; they just can no longer be changed.

Are my files uploaded?

No. Flattening happens entirely in your browser.
