Read and Speak Greek for Beginners Pdf
Many ebook readers natively support PDF documents merely, unfortunately, not all PDF documents are easy to read on a small ebook reader screen. Permit's take a expect at two simple and free ways to convert PDF files for enjoyable reading.
Kindles, Nooks, Sony Pocket Readers, and other popular readers support native PDF rendering. The trouble with native rendering, withal, is that many PDF documents are formatted to exist read on a big screen or printed and read in hard re-create. Large margins, multiple columns, and other formatting choices that aren't such a big deal when the document in printed on viii.5×eleven paper or displayed on a 20″ monitor render the certificate almost unreadable when loaded into an east-reader with a 6″ screen. Today nosotros're going to expect at ii ways you can re-format a PDF file for enjoyable reading on your favorite reader.
What You lot'll Need
For our tutorial you'll need the following things:
- A copy of ebook management software Calibre.
- A copy of K2pdfopt.
- A PDF file to convert.
- An e-reader to try the file out on.
We suggest keep a clean copy of your PDF examination file in a separate directory so if all your conversion attempts become amiss yous'll have the original safe and audio.
Converting Using Calibre
Calibre is an awesome and open up source ebook management tool. If you've read this far and have no intention of even mucking around with whatsoever PDF files y'all should go and download it regardless. It'due south a fantastic tool for managing ebooks and ebook readers. What we're interested in, book management bated, 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 information technology, bank check out one of our previous Calibre-based guides to get started. Once you've installed information technology and you've loaded up a book you desire to convert it's time to get converting.
For our example we'll be using a particularly complex textbook (multiple columns, charts, graphic headers for each affiliate, etc.) and a Kindle. First let's wait at what the original PDF file looks like on the Kindle screen.
That'due south eye-squintingly pocket-sized on a large monitor screen and nearly illegible on a Kindle screen. There'due south no way we could comfortable read that on a 6″ kindle screen without serious eye strain and a headache. Let's see if we tin catechumen it with Calibre.
Open Calibre and right click on the book. Select Convert Books –> Catechumen individually. Hither you'll find an enormously detailed carte du jour with toggles and settings galore. It's like shooting fish in a barrel to get overwhelmed and some of the settings are pretty arcane if yous're unfamiliar with printing terms and/or search cord expressions. For the first conversion stick with the default settings and catechumen 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 than streamlined document.
When it's done converting you tin check the formatting on your calculator by double clicking on the converted file in the correct hand book information column or you lot can transfer information technology to your device. We transferred it to the device to become a existent sense of how it looked on the folio.
Although we've used Calibre to convert hundreds of ebooks over the concluding few years with very few bug 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 job converting PDF files nosotros picked ane of the most hard to catechumen PDFs we had on paw to demonstrate that things don't e'er go every bit planned. Nosotros also picked a really hard to catechumen PDF then that nosotros could in plough prove off the next tool in our tutorial, K2pdfopt. It's similar the nuclear option when the normally reliable Calibre fails to crank out a working conversion. If yous find yourself in a similar gunkhole, your complex PDF document didn't plow out right, you'll probable exist thrilled with K2pdfopt.
Converting Optimizing PDF files using K2pdfopt
Start, we desire to give a large thank you to Abhijeet at Guiding Tech; we'd been looking for a tool like this and he tipped united states of america off at only the right time. K2pdfopt is designed to optimize PDF documents for small screen e-readers. Rather than catechumen the document into raw text and effort to reformat it, it instead carefully crops and realigns the pieces as though they were a serial of images. The end outcome is a new PDF file that is really true to the original document and free from odd OCR blunders (equally 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 it piece of work—as seen in the screenshot to a higher place. We dropped the aforementioned 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 wait. When the conversion completed (you lot'll meet a copy of your PDF file with the file named annotated like filename_k2opt.pdf in the K2pdfopt binder) we copied it over to our Kindle and were shocked at how well it handled the complex text we threw at it. 
The text is slightly less well-baked than in our PDF to MOBI conversion (see the screen capture in the Calibre section) but it is all at that place, 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 easy to read every bit a clean photocopy.
The merely 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 nosotros'd need to actually send through the K2pdfopt image-based conversion process, though, information technology's not a bad trade off. We can stand to increase the file size on a few PDFs in gild to gain admission to a portable and hands read copy.
Update: Shortly after this article went alive 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 convert it to a MOBI or ePUB? Maybe that would stop Calibre from choking on the multi-column format since it would now be formatted more than like a standard book. Could you guys try it out?
What if, Marcus? What if, indeed. We dove in deeper, Inception-style, and performed a exam just every bit yous 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 trivial grainy) later the reconversion process:
And at that place you have it. For a particularly tricky PDF file yous can run it through K2pdfopt.exe, so dump it dorsum into Calibre for a cleanup pass (cheque out how smooth the font is at present in the above sample), and relish a totally optimized PDF. Skilful telephone call, Marcus! The extra footstep only adds a few minutes to the process and actually tidies things up.
