Can I remove only leading and trailing spaces from each line?

Yes. The trim lines option removes whitespace at the start and end of each line without affecting spacing within sentences.

Does it collapse multiple spaces into one?

Yes. The normalize spaces option reduces multiple consecutive spaces down to a single space.

Only if you choose the remove blank lines option. Regular line breaks within paragraphs are preserved.
