Poor pdf to epub conversions

clittle · 01-27-2011, 08:54 AM

Hi,

The last two pdf's I've tried to convert to epub's were horribly messed up. So much so as to be virtually unreadable.

Some of the problems are constant repeats of the same pages, many pages empty or with a small image, and more.

I don't know enough about calibre to know how to correct the problem or what to do next.

I'd be grateful for any ideas.

There's a whole lot of known problems when converting from PDF, see this post for the most common examples.
To really be able to help you, you'd need to provide more details as to what your source PDFs look like (multi-column? image only? OCR?).

small images? Were these somewhere on the original PDF page? Try and imagin a PDF page made up of layers. The image was on a different layer from the text (and other images). The order does not matter to a PDF, the 'stack', as viewed is what you get.
Calibre un-stacks the PDF to convert, but has no clue how they were to be ordered visually, when placed end to end
