None of them are very good, though. PDF to ePub usually results in awfulness.
Yup. PDF is a really awful format. It's main purpose is to replicate the printed page exactly. So among other things, it has page numbers. And fixed line length. So let's say we have a paragraph in PDF like this, with a page break in the middle of the paragraph. So in PDF it looks something like:
There was never a more amazed
little boy than Cedric during
the week that followed; there
was never so strange or so
-23-
unreal a week. In the first place,
the story his mamma told him was
a very curious one. He was obliged
to hear it two or three times
before he could understand it.
Convert this to epub, and you get:
