converting pdf to epub
I want to convert pdf files to epub format. I tried calibre but the epub generated is not good.
If anybody is using any other tool for the same conversion.Please let me know as well.

First convert from the PDF into HTML and make sure you've fixed all of the errors in the HTML due to converting from PDF. I've never yet seen a PDF converter that does it 100% error free. So it could be the ePub is reflecting the errors in the conversion process from PDF.

PDF is the worst source format that you can use. Don't expect any good result with automatic conversions from PDF to ePub: you'll always have to fix a lot of things manually.

The only other ebook-centric converter I am aware of (which does not convert to images) is Windows MobiPocket Reader or Creator, which will convert from PDF to MOBI. Calibre can then convert the MOBI to ePub. This may be no better than Calibre's native converter, but it might be worth trying. Note that the source code for the underlying pdf2xml is available, see Mobipocket convert in mass?.

I have tried both the conversions pdf>html>epub and also pdf>mobi>epub.
But both have some problems and html files have to be manually modified to get the required epub.
Where can I find the source code for pdf2xml ?
Thanx for ur time..

FWIW I've found the only way to get a good conversion from PDF is the labour-intensive one: export the PDF as text, load the .txt into your favourite text editor, use extensive search & replace to eliminate hard line endings etc (or perhaps less search & replace if you have any competency with regex, which I don't), convert quotes to “ etc., and finally turn it into a decent epub with Sigil. Loading into Calibre is then of course a trivial exercise.

I've tried most of these methods, but the best so far is to open the PDF in an OCR program and generate a new text file from that. Then manually delete any headers and footers, and fix any broken paragraphs. I haven't seen any common OCR problems yet, presumably because the text in a PDF will be perfectly straight and without any scanner or paper noise.

I agree, I usually use Abby Finereader to OCR the PDF. Still a lot of manual afterwork, but the results are quite good.

No OCR artifacts? None?

That sounds like your OCR program is "cheating" and using PDF tags, when and if they are available.

This website, like as many others, uses Calibre to make the conversions. If you don't like Calibre, will not like even ebup2go.
