Pdfs are as great for me today as they were ten years ago, it takes me about three hours to convert a thousand page text book into a small & fast 20 MB pdf file (ocr layer behind the page using Acrobat's Clearscan mode) with 100% text & page layout accuracy, they are considerably lighter and thinner than paper books (using newer 8" or 10" size eink readers and tablets) and if my pdf reader allows I can open (read) several pdfs simultaneously on the same device, I can search them, annotate them (as I would a paper book), hyperlink them, bookmark them, paginate them, listen to them, change the text & page size by reducing/enlarging the empty margins, by reading in portraite/landscape, by using two-column mode etc.

Once you get that privacy-minded, then ebooks just aren't likely a viable thing for you. |

I got the answer that it is legal to scan pBooks. Now I am saying that 1dollarscan sends back PDF and that's nearly useless.

I don't have much experience with scans-to-epub conversion though, because I've (just out of curiosity) converted several books into epub using Abbyy Finereader 13 a couple of years ago. Anyone interested can try out new Abbyy Finereader 15 (free 30 days trial period), e.g. by scanning ten typical pages in ten books, because it is allowed just 100 saved pages in total. https://www.abbyy.com/en-eu/lp/finer...en-eu_shopping Last edited by Marinolino; 06-01-2020 at 10:26 PM. |

Actually, PDF is one of the hardest formats to convert from. You can get a right mess with a lot of errors and broken lines. It's not easy at all to do novel length PDF conversion correctly. The only way to be sure it's correct is to do an A/B compare of the PDF to the ePub and that takes a long time and spoils the book as you basically have to read the book letter by letter including every space and punctuation mark.

What I mean is, you create images (original scans) from pdf using some pdf editor, and then feed those images to Abbyy Finereader for conversion to epub, but Abbyy is doing the same thing anyway (decompresses pdf pages) when we feed him pdf for conversion to epub.

https://1dollarscan.com/pricing.php File Conversion " We can convert your scanned PDF to many other files such as WORD, epub, txt, audio formats for audio books and many other file types. Please contact us with yours needs at contact@1dollarscan.com " They are pretty common thing nowadays, and I don't mean visible ocr-text layer, but the invisible one added behind the page (scan) image, and since its main function is search & highlight capability, it doesn't have to be very accurate, but for belletristic literature we can usually use it efficiently for pdf reflow function as well (eink readers use ocr text layer for pdf reflowing), because there are not as many problematic signs and formulas, tables, diagrams etc. as with scientific books and the page layout is usually simpler. Koreader app can even reflow pdf scans without an ocr layer, as we read them page by page, using k2pdfopt engine, so, we don't have to reflow them for our specific eink reader using k2pdfopt app on our PC/Mac computer beforehand, as in the past. But those who don't have Koreader app installed on their eink reader, or their 6" or 8" eink reader is old and slow or with a little working memory, can simply convert (reflow) pdf scans or A4 pdf documents using k2pdfopt app and their eink reader will flip through such reflowed pdf as fast as the newer models, with a great font accuracy (very important for scientific documents). https://www.willus.com/k2pdfopt/ " K2pdfopt optimizes PDF/DJVU files for mobile e-readers (e.g. the Kindle) and smartphones. It works well on multi-column PDF/DJVU files and can re-flow text even on scanned PDF files. It can also be used as a general PDF copying/cropping/re-sizing/OCR-ing manipulation tool. It can generate native or bitmapped PDF output, with an optional OCR layer. There are downloads for MS Windows, Mac OSX, and Linux. The MS Windows version has an integrated GUI. K2pdfopt is open source. " Last edited by Marinolino; 06-03-2020 at 02:51 PM. |

A scan always results in an image and an image never contains any text that can be further processed.
You can only try to extract this with OCR. |

I guess it depends on the definition of scan. When I scan a document on my multifunction printer to create a PDF, I can do a search for text on the PDF, and I can export the text of the PDF.
