What is Reddit's opinion of K2PDFOPT?

From 3.5 billion Reddit comments

Para expandir en esto, hay forma de adaptar los PDFs para que sean legibles en Kindle. Requiere de un poco de trabajo, pero el resultado vale la pena.

Hay que descargar y aprender a usar la siguiente herramienta: http://www.willus.com/k2pdfopt/

Toma un par de semanas aprender a usarlo, pero vuelve legible casi cualquier PDF. Yo lo uso para convertir PDFs de D&D a algo utilizable en Kindle, y da muy buenos resultados.

I've had some success converting LaTeX-based PDF files using a tool called k2pdfopt.

If you can find an HTML version (e.g. from the .tex source) then you can put that directly on the e-reader. It renders it reasonably well. Or you could convert it using... tools.

Finally, if you can reformat anything, e.g. if it's a MS Word document, create a paper size that works well for your e-reader (use a ruler) and print using that paper size to a PDF file.

My experience is with the Kindle PaperWhite 3.

I hate reading articles on computer screens. I would love it if journals would release their articles as .mobi or .epub files. However, it seems that PDF is here to stay and this causes problems for e-readers. Most e-readers will display PDF files, but typically this means that you're displaying it at 100%, so the text becomes rather tiny to read.

There is software, such as k2pdfoft, that can convert journal PDF files into e-reader files. The idea is that it strips out all the header and footer data and can combine columns back into one piece of text. In my experience it's overly complicated and needs to be finely tuned for each paper. This makes it very time consuming and frustrating.

Sorry I'm not answering your question positively, I just figured that I'd let you know my experience so you could decide if you think it's worth the effort (hint: sadly, it's not).

Daca sunt in format epub sau doc, calibre le transforma foarte bine in mobi. La pdf e mai complicat, dar recomand k2pdfopt.

I hate these PDFs they are almost impossible to do anything about. You almost would have to copy every each column individually and paste it into a blank document file to create a standard paragraph format.

Try this program I just found to convert the columns to standard paragraph format.

Edit: it worked for me but looks like it outputs the PDF as image instead of text. After I sent it to the kindle though the text was oriented vertically so I have to turn the device to read it. Changing the device orientation will either make you pan from side to side to read the PDF or squeeze the text together. Too bad it didn't OCR the text :(

thank you. your comment is very valuable to me. I have noticed that Remarkable has a screen size identical to the new ipad pro... and once visiting an apple store I could myself try a plos one paper to see...

It all - for me - now boils down to price and led vs epaper.

By the way, I have discovered the utility http://www.willus.com/k2pdfopt/help/borders.shtml

The first thing to remember is that the difficulty in reading pdf's usually is because they have been created in A4 or letter-paper format. There's no reason why you couldn't create a pdf document for a Kindle-sized page. The pdf format is page/papersize agnostic.

But if all you've got are A4 or letter-sized pdf's, this free program does a great job of freeing them for the standard Kindle or ebook reader size: http://www.willus.com/k2pdfopt/

Reading on Kindle is 100% better. In fact, those readers were designed when they discovered that reading on a screen that reflects light gives you no more than 30% of retention, and obviously leave your eyes tired. For the PDF's, you can find ways to make them work PRETTY WELL on Kindle, if you research. k2topdf is a good tool for converting PDF's.

Not particularly "Nook pdf hack", but I almost always use k2pdfopt to convert my PDF files. I've been using it for a few years now. The results can vary from "usable" to "perfect".

If i remember correctly, use http://www.willus.com/k2pdfopt/ first and then Calibre.

The explanation I heard (and not yet tried) is that k2pdfopt takes a different approach to converting and is more OCR like. It does a decent job and anything it missed, Calibre does a good job of cleaning up afterwards.

edit:
this being where I learned of it http://www.howtogeek.com/69481/how-to-convert-pdf-files-for-easy-ebook-reading/

I haven't tried it personally, but check out K2pdfopt. Supposedly, it handles PDFs with 2 column layouts well.

I also have this problem! I have some eye problems, and have trouble reading on a screen. What I did is I found an old Kindle, and used this to translate pdf's to a kindle format. That's how I am currently reading the 18th Brumaire and Capital Vol. 2. I'm not sure if that is possible for you, but hopefully it helps.

I have used k2pdfopt for reading some Rifts pdfs on a Kindle Paperwhite. It ended up being much better than using the built in pdf reader...but in my opinion is only really usable for sequential reading. Don't expect a great experience.

1st of all, I'd suggest looking up ergonomic advice on chairs, desks, and monitor setup. I have coordination problems so touch-typing and 2-handed typing aren't options, and I've modified my setup accordingly. You may have your own issues and need to modify your setup too.

• Find and install software to encourage frequent breaks.

• Find either a tablet or an e-reader, so you can transfer documents to them, and go over them, away from your computer. I can't use touch devices, but I can use some older e-readers such as the Kindle Dx. I use k2-pdfopt to convert pdfs for better Kindle compatibility.

• Figure out your chair measurements. I haven't been able to find a good chair in my own size, but I have been able to find a decent one which is too big. I've strapped pillows to it. Besides offering more padding, these reduce the seat depth and add back support.

• Check your desk height. Most desks are too high for typing. I haven't found desks in my own size, but I have found a table with adjustable legs.

• Check your monitor height. If you can touch-type, the top of your monitor should be about eye level. You can use books and/or a special riser to prop it up.

• Consider an alternative mouse. I use an Evoluent vertical mouse.

• Consider an alternative keyboard. I use a Logitech mini-keyboard, propped up on the left side for my right hand, but if you can touch-type with 2 hands, you may want a full-size keyboard, and maybe a split one.

• If you like a keypad, you may want a keyboard which provides one for your off hand, so it doesn't get in the way of the mouse. So right-handed users may want left-handed keypads and vice-versa.

• For eye strain, it's harder to find a good monitor.

Hope at least part of this helps!

It would be great for reading comics or manga, but I'd rather read an ebook on a kindle/kobo. They are way cheaper and more efficient, and if that's all you want it for it would be a better investment.

Different story if you need PDFs, but there are a lot of different options for converting PDFs and keeping some of the formatting intact. Calibre's standard converted is all right, I've also seen http://www.willus.com/k2pdfopt/ recommended (though I haven't tried it yet).

Există o aplicație făcută să formateze bine pt kindle pdf-urile cu articole științifice (alea cu 2 coloane; are opțiune și pt mai multe coloane, dar eu nu am încercat). Se numește k2pdfopt. E gratis și o găsești repede. Mă rog, de aici http://www.willus.com/k2pdfopt/

>2.The ones I found are scientific and barely readable. The equations and graphs are either too tiny or all messed up.

The kindle is meant for reading books, not for scientific literature.

>ost of the books I thought were available turned out to be available on the Kindle application and not the eReader,

So I'm guessing they are textbooks or scientific publications based on other things you've said.

>The built-in Oxford dictionary lacks definitions for many key terms. I find myself heading to Google a lot which is what I bought a Kindle to stop doing

Let me guess, scientific and/or technical terms that are rarely part of everyday life for the vast majority of the world?

>I have been hearing about calibre, I tried converting a PDF with it

Você já teve sucesso com esse tipo de conversão direta?

Uma época eu procurei muito na internet e o melhor que eu achei foi esse programa aqui: http://www.willus.com/k2pdfopt/ - ele faz uma coisa incrível de adaptar o PDF para leitores digitais. Dizem que funciona bem no Kindle, mas tive experiências ruins no Kobo. Os EPUB que eu converti de PDF funcionavam muito mal, travavam o aparelho, as tabelas ficavam todas esquisitas... Quando eu estudei para concurso público, eu precisei imprimir todos os PDFs e encadernar tudo. Gastava muito tempo pra tentar fazer o aparelho funcionar e ainda não dava certo :(

PDFs are not so great for reading on a Kindle in general (as they're hard coded to a certain size), but there is a tool that makes some PDFs work pretty well: k2pdfopt — http://www.willus.com/k2pdfopt/

There's also Briss, which can crop PDFs. It's not as featureful as k2pdfopt, but if you simply need to crop pages of PDFs down a little, then it's useful. But, be warned, it's on Sourceforge, so the installer might be spammy/scummy/scammy on Windows and Mac (and it definitely would be from elsewhere too). As it's actually hosted on Sourceforge, it's the most direct place to get it, however. Briss — http://sourceforge.net/projects/briss/

Have you heard of k2pdf? Basically it rearranges the text so that it fits the Kindle's screen without losing the formatting. Although I don't know whether it'll work with equations or not.

Definitely doable. I converted an Asimov book from PDF to kindle format. Worked fine. I looked through my notes-to-self and found these. Hope they help:

1. Download PDF version of desired text/book.

2. If text is in multiple PDFs (EG, one per chapter), combine PDFs here: http://www.pdfcombine.com/

3. Convert combined PDF (to Kindle format) using K2PDF Tool (use GUI.exe for ease of use). http://www.willus.com/k2pdfopt/download/ (for main utility)

   http://www.students.uni-marburg.de/~Wallauej/k2pdfoptgui/k2pdfoptgui.html (for GUI - requires main utility)

4. Copy converted PDF to Kindle:\documents\ Create corresponding folder in Kindle:\documents\ (not sure if utilized for converted PDFs).

Get the optimized version for the kindle paperwhite I created. Or create your own kindle-optimized pdfs with k2pdfopt.

While I've had mixed results^1 with it, you might find this helps, especially if the ebook reader in question is a Kindle (or has similar screen dimensions).
 

^1. ^Most ^notably, ^drop ^caps ^seem ^to ^confuse ^the ^hell ^out ^of ^it, ^resulting ^in ^a ^line ^that's ^mis-sized ^compared ^to ^the ^surrounding ^text.

There are high quality native-pdf chemistry books like Organic Chemistry by McMurry. And try using K2pdfopt to tune your pdfs. It seems to help a lot with academic texts' (lots of graphs and columns) formating.
