Steps/ best practices for converting PDFs to ePUBs? Thoughts and Ideas:
Just to preserve this knowledge and information in contextually separate topic/ subject I am creating a fresh thread here - Please post replies/ ideas relating to the conversion discussion here - ORIGINAL INFO: I have some PDFs that I am reading & highlighting in Good Reader I'd like to push to ePub so that I could do so in Marvin instead. PS: I am posting additional details, thoughts, questions relating to my post and now the knowledge from your replies. Please do check it out and share thoughts. UPDATED INFO: - I understand the variation and variety of PDFs and the structural and placement related markers that they may have within make this complex - sometimes next to impossible - If these are scanned books/ pages then the OCR conversion is another major step - If the text and graphics are placed in various boxes in weird ways, god help us BUT: IF.. If the PDF is fairly simple structured and has a single column flow of text (with selectable Text - No OCR aspect here) - where structure and markers are relatively simpler.. ... WHICH TOOLS and STEPS would you suggest? I have one such PDF - Looks almost like a Word Document saved as a PDF. Quote:

Attempt 1:
I placed this PDF into Acrobat XI and as I move the text cursor down, its moving up and down almost like a Word Document through the few pages. PDF has no security / locks on it. Save as Other > Word & Word 03 - Both give some kind of failed message. Save As failed to process this document. I will try in some BlueBeam PDF as well. |

Ok. I installed MobiPocket Reader as per your suggestion. I can open it inside it, how do I get an ePub or Mobi from it that I can put into Marvn or so?

Get the latest version of FineReader, OCR it, proofread it, save it as HTML, import into Sigil. Or, I guess that using the latest version (FineReader 11) you could export it directly as an ePub, but the styles will probably be all over the place.
I would export it as DOC/DOCX, run my custom Word macro to "dumb" the text down to its core components (bolds, italics, etc) and then redo the layout either in InDesign, or apply quick styles in Word and then save as a Filtered HTML and then import into Sigil. Hmmm... There are a few routes and software programs that you can use, but just make sure that you proofread the final product. Proofreading is damn important. Oh, and one last thing, FineReader will OCR the PDFs as a bunch of images, so the images that it saves as "Pictures" are pretty much screenshots of a screenshot, sort of speaking. You're probably better off exporting the images from Adobe Acrobat or something like that, so that you don't lose quality. |

I just got PDFtoEpub for free here: http://www.pdftoepub.com/authorspromotion.asp and so far it has done very well converting some books I had that even Mobipocket Reader/Creator couldn't handle. The resulting epubs may still need a few corrections in Sigil, however, to fix things like spacing or the infamous "missing" apostrophes, and on occasion, the apostrophes that somehow get switched to reversed quotation marks but to be fair, many programs do that when converting .pdf files, not just this one. So far I like it, you may want to give it a try.

I use PDF converter professional by Nuance to convert PDF to word and then Atlantis can easily convert word to ePub.

The only way to convert PDF > ePub is to A/B compare the ePub to the PDF. That means every character, every space, every punctuation mark, every graphic, every bold, every italic and anything else in the PDF. There is no way to convert a novel length PDF that won't have any error.
Yes, it will take time to properly A/B. But that's the only way to do it. |

Any conversion from columns is especially difficult because it can go along being perfect for 10-20 pages and then jumble things up, putting parts of paragraphs above or below invisible to casual scanning. It gets especially bad near any illustration or small blocks of text.
The removal of extra colors and font sizes not in the original text is another playground of the devil in search and replaces that can go wrong too. |
