2 months ago SingleFile should not remove newlines in HTML. For example, if you save https://example.com/ with SingleFile, the resulting content still contains the original newlines, see the source code below.

However, this problem arises for the content of inline stylesheets but unfortunately I can't fix it (easily). It's an issue in the library used by SingleFile to parse CSS (see https://github.com/csstree/csstree/issues/237).
I use SingleFile not only for longterm storage, but also to feed beautiful soup and/or looking and manipulating code. VSCode has trouble with it tho and stops tokenization when the lines get too long. Since the minimization option also gets rid of all newlines the HTML file will consist of a single line. I've experienced degraded performance because of that on several occasions.
We need an option for minimizing the HMTL but without nuking newlines = preserving them.
