I have a 350mb PDF. How do I best convert this?

[lori87]

When I open the PDF in sumatra I can highlight text, however when I click "Edit book" in caliber I see a bunch of images, so it looks like someone scanned this image page by page which explains its large size.

Any advice on how to best convert this for my kobo? It's not THAT bad on my Kobo reader using koreader, but it is a bit slow with page turning and refreshes every page.

What would you do?

No one?

Did you read this sticky ==>> Read this before Posting PDF Questions

Not mentioned in that thread is MS Word's PDF Import feature, I think it was introduced in Office 2013, it's certainly in Office 2016. For some PDF's it does an excellent job. If you have access to Word give it a try. There are various ways to get from Word to EPUB and from there to kobo

So sorry for the bother, but do you have a good tutorial on this by any chance? I tried googling and can't get it to work.

Thank you SO much

What can't you get to work - opening a PDF document in Word, editing the document in Word, or converting the Word document to ePUB.

Here's how to do the first one ==>> Opening PDFs in Word - Word

If you can get it into Word and save it as a DOCX you can then get calibre to convert the DOCX to ePUB. And from there to whatever your kobo wants - I think they need kepubs which I assume is the proprietary form of ePub that works on Kobo devices.

Don't expect a perfect result, and it could be worse than KOreader on your kobo.

A Kobo touch ereader will open a .kepub.epub with an epub3 compliant (more or less) renderer and an .epub with Adobe's RMSDK renderer. You can open a kepub on any epub reader since the biggest change is adding extra spans which do nothing on other platforms.

Although this is an older topic, I just wanted to say that the 250mb pdf I have would not open in word. It kept saying "Sorry, we're having trouble converting your PDF to a Word document".


I'm assuming this has to do with size.

Probably - add memory and/or try installing the 64 bit Office see ==>> Choose between the 64-bit or 32-bit version of Office

Im giving up

I understand perfectly.

My initial thought to the "What would you do?" question in your first post was: "Go buy a tablet." A middling Android device should be good enough.

My thought exactly

[lori87]

I still can't believe there isnt a single program that can fix these large PDFs

[BetterRed]

If the PDF is scanned images then you could try using a OCR scanning program to get something amenable for conversion into a format your Kobo can read.

Most OCR programs can create a Word document or an HTML file which could be converted into a format suitable for your Kobo. But its highly likely that the scanned text would be riddled with errors. There are tools to help fix some of those, but they have a fairly steep learning curves. And then you would need to invest time and effort to manually find and fix those they can't find and fix.

Abbyy Fine Print is regarded as the best OCR software i.e. it outputs fewer errors than alternative programs - it costs about the same or more than a middling tablet

or go buy the epub version of the pdf ???

a 350MB pdf will render s l o w l y on a middling android tablet
even on a fast android tablet , the large PDFs that I have tried e.g. image-heavy game strategy guides, don't handle well and are not a pleasant read, even on a 10 inch device, as they are designed for A4.
some (for musicians) jazz fake books - which contain several hundred page images - also take ages to render when you scroll down fast

what is in THAT 350mB tome ?

ps the simplest quick and dirty pdf convert route i have found is open in adobe reader ( on windows PC) , use "select all" from copy menus
then paste that selection into a new word document.
it usually gets all the text , in a more or less readable form, and sometimes gets images also, depends on the PDF

[lori87]

There is no epub version of it.

I've just put the whole PDF on my kobo, it's readable, just not the best. Ah well, it'lll do.
