About Remove Empty Lines
Blank lines are removed, including lines that only contain spaces or tabs — the invisible case that a plain "is it empty" check misses and that is the usual reason a file still looks double-spaced after cleaning it. Line ending style is normalized in the process, which also fixes text moved between Windows and Unix systems.
How to use it

Questions
What about lines with only spaces?
Removed. A line of whitespace is visually blank and almost never intentional, so treating it as empty is what people expect.
Can I collapse runs of blank lines rather than remove them all?
Not here — this removes every blank line. To keep paragraph breaks, remove line breaks first and then reformat.
