That's the "fault" of the PDF format, rather than the tool. A PDF file contains no information about paragraphs, lines, or even words - it just has information about individual letters, along the lines of "draw a letter 'a' at such-and-such a position on the page". Given such a paucity of information, the conversion tools do a pretty good job!
