convert pdf to epub or lrf incorrectly

[jack06]

When I convert a pdf to epub or lrf, all the line's ends break to the new lines, I have changed some settings but didn't help. This is an example from pdf file:

Officials also said they plan a new design for Forever stamps, which currently
have am image of the Liberty Bell. New Forever stamps will have images of
evergreen trees. All Forever stamps would remain valid.Under the proposed
increases, in addition to the 46-cent rate for the first ounce, the cost for
each additional ounce would go up a penny to 18 cents. The cost to mail a
post card would go up 2 cents to 30 cents.

This is a new epub or lrf:

The setting you need to change is the pdf line unwrap factor. Try a value of between 0.3 to 0.5. Search here for "unwrap" or read this to find out more.
