Many ebook readers natively support PDF documents but, unfortunately, not all PDF documents are easy to read on a small ebook reader screen. Let's take a expect at two unproblematic and gratis ways to convert PDF files for enjoyable reading.

Kindles, Nooks, Sony Pocket Readers, and other popular readers support native PDF rendering. The problem with native rendering, even so, is that many PDF documents are formatted to be read on a big screen or printed and read in hard copy. Large margins, multiple columns, and other formatting choices that aren't such a big deal when the document in printed on 8.5×11 newspaper or displayed on a 20″ monitor render the document almost unreadable when loaded into an eastward-reader with a half dozen″ screen. Today we're going to look at 2 means you can re-format a PDF file for enjoyable reading on your favorite reader.

What You'll Need

For our tutorial you'll demand the following things:

A re-create of ebook management software Calibre.
A copy of K2pdfopt.
A PDF file to convert.
An east-reader to try the file out on.

We propose proceed a make clean re-create of your PDF test file in a dissever directory then if all your conversion attempts go awry you lot'll take the original safe and sound.

Converting Using Calibre

Calibre is an awesome and open source ebook management tool. If you've read this far and have no intention of even mucking around with any PDF files you should go and download it regardless. It'south a fantastic tool for managing ebooks and ebook readers. What we're interested in, book management aside, is the conversion tool built into Calibre.

If you're totally new to using Calibre and need help installing it and getting your books into it, check out i of our previous Calibre-based guides to get started. One time yous've installed it and y'all've loaded up a book you desire to convert it'due south fourth dimension to get converting.

For our example we'll be using a particularly circuitous textbook (multiple columns, charts, graphic headers for each chapter, etc.) and a Kindle. First let'due south look at what the original PDF file looks like on the Kindle screen.

That'south middle-squintingly small on a big monitor screen and about illegible on a Kindle screen. There'due south no way nosotros could comfortable read that on a vi″ kindle screen without serious center strain and a headache. Permit's come across if we can catechumen it with Calibre.

Open Calibre and right click on the book. Select Convert Books –> Catechumen individually. Hither you'll find an enormously detailed bill of fare with toggles and settings galore. It'due south easy to get overwhelmed and some of the settings are pretty cabalistic if you lot're unfamiliar with printing terms and/or search string expressions. For the first conversion stick with the default settings and convert betwixt PDF and a suitable format for your ebook reader or fifty-fifty PDF to PDF to restructure multi-column PDF files into a more streamlined document.

When information technology'southward done converting you can check the formatting on your figurer by double clicking on the converted file in the right hand book information column or y'all tin can transfer information technology to your device. We transferred it to the device to become a real sense of how it looked on the folio.

Although we've used Calibre to convert hundreds of ebooks over the last few years with very few problems this particular PDF file proved to be a real challenge for it. The multiple columns, odd formatting choices, and other factors really stumped Calibre.

While Calibre commonly does a fine chore converting PDF files we picked one of the most difficult to catechumen PDFs we had on paw to demonstrate that things don't always go as planned. We besides picked a really hard to convert PDF and so that we could in turn bear witness off the side by side tool in our tutorial, K2pdfopt. It's like the nuclear option when the commonly reliable Calibre fails to crank out a working conversion. If you find yourself in a similar boat, your complex PDF certificate didn't plow out right, y'all'll likely be thrilled with K2pdfopt.

Converting Optimizing PDF files using K2pdfopt

First, we want to give a big thank you to Abhijeet at Guiding Tech; we'd been looking for a tool similar this and he tipped us off at merely the correct time. K2pdfopt is designed to optimize PDF documents for small screen e-readers. Rather than convert the document into raw text and try to reformat it, it instead advisedly crops and realigns the pieces equally though they were a series of images. The stop result is a new PDF file that is actually truthful to the original document and costless from odd OCR blunders (as it doesn't attempt to convert or reflow the text).

Using K2pdfopt is a snap. Extract the executable into a folder, elevate a PDF file onto the EXE and allow it piece of work—as seen in the screenshot above. We dropped the same difficult to format textbook PDF into K2pdfopt and crossed our fingers. Given how much Calibre struggled with the certificate we weren't sure what to expect. When the conversion completed (you'll come across a copy of your PDF file with the file named annotated like filename_k2opt.pdf in the K2pdfopt binder) nosotros copied information technology over to our Kindle and were shocked at how well it handled the complex text we threw at it.

The text is slightly less crisp than in our PDF to MOBI conversion (meet the screen capture in the Calibre section) but it is all there, with proper formatting, and without any screwy OCR errors. Thanks to K2pdfopt we went from having a PDF that was illegible on the Kindle to having a PDF that was as like shooting fish in a barrel to read as a clean photocopy.

The just downside we could find in using K2pdfopt was the increase in file size. A 15MB PDF file, when converted with K2pdfopt, ballooned to 93MB. When you consider how few conversions Calibre doesn't properly handle and how few books we'd need to actually ship through the K2pdfopt image-based conversion process, though, information technology's not a bad trade off. Nosotros tin can stand to increase the file size on a few PDFs in guild to gain admission to a portable and hands read copy.

Update: Before long after this article went live on the site Marcus wrote in and asked

What if y'all took the K2pdfopt.exe output and ran the resulting PDF through Calibre again to convert information technology to a MOBI or ePUB? Possibly that would finish Calibre from choking on the multi-column format since information technology would now exist formatted more than like a standard book. Could you guys attempt it out?

What if, Marcus? What if, indeed. Nosotros pigeon in deeper, Inception-mode, and performed a test only as you requested. Calibre handled the conversion beautifully and the text cleaned up perfectly. How perfectly? Hither's a snippet of the text seen in the screenshot higher up (which is properly formatted but a picayune grainy) after the reconversion process:

And in that location you lot have it. For a specially tricky PDF file you tin can run it through K2pdfopt.exe, then dump it back into Calibre for a cleanup pass (check out how smooth the font is now in the above sample), and savour a totally optimized PDF. Expert call, Marcus! The extra stride only adds a few minutes to the procedure and really tidies things up.
