Many ebook readers natively support PDF documents but, unfortunately, not all PDF documents are easy to read on a small ebook reader screen. Permit'south accept a look at two elementary and free 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, all the same, is that many PDF documents are formatted to be read on a large screen or printed and read in hard copy. Big margins, multiple columns, and other formatting choices that aren't such a big bargain when the document in printed on 8.v×11 paper or displayed on a xx″ monitor render the document well-nigh unreadable when loaded into an e-reader with a 6″ screen. Today nosotros're going to await at two ways you lot tin re-format a PDF file for enjoyable reading on your favorite reader.

What Y'all'll Demand

For our tutorial you lot'll demand the following things:

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

Nosotros advise keep a clean re-create of your PDF test file in a split directory and so if all your conversion attempts get awry you'll have the original safe and sound.

Converting Using Calibre

Calibre is an crawly and open source ebook direction tool. If y'all've read this far and have no intention of even mucking around with any PDF files you lot should go and download it regardless. Information technology's 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 yous're totally new to using Calibre and need assistance installing it and getting your books into it, check out ane of our previous Calibre-based guides to get started. Once you lot've installed it and you've loaded up a book you want to convert it's time to get converting.

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

That's middle-squintingly small on a large monitor screen and nearly illegible on a Kindle screen. There'south no way nosotros could comfy read that on a 6″ kindle screen without serious middle strain and a headache. Let'due south see if we tin can convert it with Calibre.

Open up Calibre and right click on the book. Select Convert Books –> Convert individually. Here yous'll find an enormously detailed menu with toggles and settings galore. It'due south easy to go overwhelmed and some of the settings are pretty arcane if you're unfamiliar with press terms and/or search string expressions. For the kickoff conversion stick with the default settings and convert between PDF and a suitable format for your ebook reader or even PDF to PDF to restructure multi-cavalcade PDF files into a more streamlined certificate.

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

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

While Calibre normally does a fine job converting PDF files nosotros picked one of the nearly hard to catechumen PDFs nosotros had on hand to demonstrate that things don't e'er go as planned. Nosotros also picked a really difficult to convert PDF so that we could in turn prove off the next tool in our tutorial, K2pdfopt. It's like the nuclear option when the commonly reliable Calibre fails to creepo out a working conversion. If you find yourself in a similar gunkhole, your complex PDF document didn't turn out right, you'll likely be thrilled with K2pdfopt.

Converting Optimizing PDF files using K2pdfopt

Offset, we want to requite a large thanks to Abhijeet at Guiding Tech; we'd been looking for a tool like this and he tipped united states off at but the right time. K2pdfopt is designed to optimize PDF documents for modest screen due east-readers. Rather than convert the certificate into raw text and try to reformat information technology, it instead carefully crops and realigns the pieces equally though they were a series of images. The end result is a new PDF file that is really truthful to the original certificate and gratuitous 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 let information technology work—as seen in the screenshot above. Nosotros dropped the same difficult to format textbook PDF into K2pdfopt and crossed our fingers. Given how much Calibre struggled with the document nosotros weren't certain what to expect. When the conversion completed (y'all'll run across a copy of your PDF file with the file named annotated like filename_k2opt.pdf in the K2pdfopt folder) nosotros copied it over to our Kindle and were shocked at how well information technology 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 at that place, with proper formatting, and without whatever screwy OCR errors. Thanks to K2pdfopt nosotros went from having a PDF that was illegible on the Kindle to having a PDF that was as easy to read as a clean photocopy.

The merely downside we could observe 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 send through the K2pdfopt image-based conversion process, though, it'due south not a bad trade off. Nosotros tin stand to increase the file size on a few PDFs in gild to gain access to a portable and hands read re-create.

Update: Shortly later this article went live on the site Marcus wrote in and asked

What if you took the K2pdfopt.exe output and ran the resulting PDF through Calibre again to catechumen it to a MOBI or ePUB? Possibly that would stop Calibre from choking on the multi-column format since information technology would at present be formatted more like a standard book. Could you guys try it out?

What if, Marcus? What if, indeed. Nosotros dove in deeper, Inception-fashion, and performed a exam just as you requested. Calibre handled the conversion beautifully and the text cleaned up perfectly. How perfectly? Here's a snippet of the text seen in the screenshot above (which is properly formatted but a little grainy) afterward the reconversion procedure:

And there you have it. For a particularly catchy PDF file you can run it through K2pdfopt.exe, then dump information technology dorsum into Calibre for a cleanup pass (check out how smooth the font is now in the above sample), and enjoy a totally optimized PDF. Skilful telephone call, Marcus! The actress step just adds a few minutes to the process and really tidies things up.
