Calibre and online sites can convert from PDF to Epub usually lose most of the format. I tried PDFElements, with similarly poor results.
Is there any service/app that actually works and converts a PDF to Epub in a way that resembles closely the original?
I thought that was the point? PDF usually stores the position of every letter so that pages appear the same when printed, but it is wasteful and does not scale between screen sizes. So EPUB stores just formatted text, which can be rendered at any font size or screen width.
You can have fixed content as well, but it needs to be flagged in the document- for example, for illustrated books, or cover, title, and cpr pages.
Op needs to talk with whoever is doing the conversion and tell them what they want. But it’ll probably drive the cost way up- especially if it was automated (and it probably was/is)
@ChaoticNeutralCzech@feddit.de when you try to read a pdf on a smaller e-ink reader, everything is reduced and almost ineligible. You want to preserve the main features (boxes, italics) but being able to have a fluid format
@alvaro@social.graves.cl Well, that’s what I figured. You technically can preserve formatting on EPUB but why would you? It’s not what the format is for, and most readers can support either. If yours doesn’t, look for apps or a software update.
Pdf is usually just an image with Metadata so that you can search and copy text, basically the coordinates of every letters and words in the image.
The formatting is only visible in the image so it’s very hard to recover.
The goal of pdf is to create a file that will look exactly the same every times but it is not ment to be edited or modified in anyway.
Use MS Word to convert PDF to DOCX then use Word to convert to EPUB. This method will still result in lossy conversion. This is inevitable.
Maybe try converting the PDF to another file type, such as Mobi, first and then epub?
Not sure if that’d help but it’s worth a shot.
It won’t. EPUB as a format defaults to being a reflowable document, if you have fixed content, it needs to be defined and flagged as such.
The official Adobe online converter always gave me the best results, I used it for invoices with tables and odd formatting all over. They have limits on free, but it should handle a small book. Not direct to epub, however.
I had a same issue for my kindle. What I realized what the source pdf should be good. For example I used to use 1-2mb pdf size for conversion, but it used to break in text or alignment. Now I pick 10+ mb sized pdf instead. Essentially people who make heavy weight PDF files save it as full adaptable file size without reducing its qualities.
Hope this works !
@nostupidquestions@lemmy.world For posterity, I found that https://github.com/pdf2htmlEX/pdf2htmlEX does an excellent job converting to HTML (although the file size increases a lot).
