Before I knew this powerful tool, I never read PDFs on my Kindle Paperwhite. Well, honestly I tried some times but gave up at last. I believe everyone know how terrible it looks like. But K2pdfopt is such impressive, most of my PDF files can be optimized for reading on Kindle with it. OK, too much words, let’s see some examples of optimized PDF, it will show what the PDF will look like after optimized by K2pdfopt.1. The Examples of Optimized PDF
In this table, the author list four types of PDF files - one column, two column, four column and scanned text, these types contain the majority of PDF books. And all of them have good looking after converted by K2pdfopt.
K2PDFOPT environment variable - You can supply command-line options via the environment variable K2PDFOPT, for example, set K2PDFOPT=-ui- -x -j 0 -m 0.25 Command line options from the command line take precedence over the ones in the environment variable K2PDFOPT. No install is required and no extra files or packages are necessary to run k2pdfopt (Mac/Linux users please see the mac install notes or linux install notes).

OVERVIEW This page is a work in progress. I’ve been on mobileread.com since 2011, regularly reading the PDF forum, and there are frequently questions from new members about converting and/or reading PDFs on e-readers such as the Kindle, Kobo, Nook, etc.The number one most common response I’ve seen from experienced e-reader users is that PDF is just about the worst source format there is for.
You may think it looks weird on computer, but when transfer the converted PDF to Kindle, you will find how amazing they are. 2. Download K2pdfopt on Computer
K2pdfopt supports MS Windows, Mac OSX, and Linux OS, it has a version which integrated with GUI(Graphical user interface) on windows, while on Mac OSX and Linux, it only has command line’s version. The latest version is v2.33a and released in October 3, 2015. K2pdfopt For Macbook
You can also find the entire versions on author’s website and download it. After downloaded, open it directly, no need to install.3. How to Use K2pdfopt with Windows GUI
K2pdfopt is not complicate to use. Recently, I download a PDF about Google Analytics, this PDF has three columns, and here I take it as an example. Before converts, it looks like this, the layout is very dense and could hardly read on Kindle.
This is the User Interface of K2pdfopt’s Window GUI, it may looks old-fashioned, but don’t mind, it works. Let’s figure out how to use it.
Step 1: Add PDFs to K2pdfopt.
You can just drag and drop PDFs from desktop or fold, or click ’add file’ to upload PDF to K2pdfopt. The tool also supports batch conversion, you can converts several PDFs in one time.
Step 2: Choose target device and Conversion Mode.
It supports almost every eReader device of Kindle and Kobo, and also include Nook Simple Touch and Nexus 7. You can set the custom width and height, DPI if you device wasn’t in the menus.
In Conversion Mode, it provides 7 types, contain default, copy, trim, fitwidth, fitpage, 2-column, crop. Normally, choose default mode is enough.
Step 3: Set Output Path, additional options and command-line.
In Env.var, set your own output path to save the converted PDF, if you keep it blank, the converted PDF will be saved in the same folder of the original PDF file.
In additional options and Command-line options, you can type some custom command-line to optimize conversion and get a better result. I will list some essential command line options in next chapter. If you don’t familiar with computer, just keep it simple, don’t type anything, just set the options with interactive menu in next step.
Step 4: Set custom options with interactive menu.
In this part, you can set all of the custom options with click, such as Re-flow text, generate marked-up source, fast preview, etc. you can also set max columns according to original PDF file.
In the top of this part, it has a crop areas, but it’s not easy to use, since we don’t know the exact number of space to crop, if you really need to crop PDF, I suggest to use Briss.
Step 5: Preview the converted PDF.
If you have done all the necessary options, click ’Preview’ in the bottom-right to see what it will looks like. If you don’t satisfied, just change the settings and preview again.
Step 6: Click ’Convert all files’ to get a final PDF.
When you think the result is good enough in preview window, click ’Convert all files’. It will not take a long time to convert, about one or two minutes, a new PDF file will be created.
Step 7: Save settings for future use.
If the settings help you get a good result, then you can save it as a template. Click ’Custom X’ button and hold for two or three seconds, a new window will pop up, then name it. Next time, when you have the same kinds of PDF file, you can use this template to convert. It’s very convenient.
OK, let’s see the result of my PDF with default settings, it’s the screenshot from my Kindle Paperwhite 2, pretty good, right?4. Must-know Options for Better Result
Although K2pdfopt is very powerful, but it’s not enough to optimize PDF only with default settings, we need to know more options to handle with different kinds of PDF files. Here are some must-know options for beginners. -XX is the command line format, and after the colon is the interactive options, you can select it on area 4 - interactive menu as I mentioned before.
-sm: Generate marked-up source. Very useful option, it will let you know how K2pdfopt will reflow your PDF pages. So before you convert, please click this option, and preview PDF pages.
-col: Max ColumnsVery important options, it will customize the column when convert the PDF pages. Choose right column according to the original PDF file.
-bpc: Set the output PDF file size.If you would like to reduce the output PDF file size, you can use the -bpc option to reduce the number of bits per color plane. The default is 4, and using -bpc 2 will reduce to 4 gray levels and reduce the PDF file size to approximately half. But notice. with the smaller PDF size is the lower quality.
-as: AUTO-STRAIGHTEN This option is used for scanned PDF file, if the PDF is slant, select this option will make it auto-straightened.
-ad : Auto-cropDon’t choose this option. It’s too slow to preview when choose this option. As I mentioned before, use Briss to crop PDF if it’s necessary.
If these options are not enough, you can learn more about the command line options in here, List of K2pdfopt Command-Line Opitions.
Besides Windows GUI, K2pdfopt has Linux command line version, here is the Get Started with Linux, and also Mac OSX command line version, read Get Started with Mac OSX.
It’s always annoying to read PDFs on Kindle or other small screen devices, someone even abandon to buy Kindle for this reason. But I must say it’s not the fault of PDF itself, since PDF is created to used as final documents. On the other hand, it’s the advantage that it can be hardly revise or convert. So all we need to do is find a way to handle it, and that is the meaning of K2pdfopt.

If reading is your pleasure then you must be hankering for an eReader. They are all the rage these days with Amazon’s Kindle, Sony, Nook, even the iPad and smartphones to a certain extent. Kindle is of course, at top of the pile right now. With the proprietary Kindle format (AZW), both Kindle 3 and DX support PDF files.
The AZW (Amazon Whispernet) format is better optimized for reading and publishing on the device. PDF eBooks don’t always render that well on the smaller screens of the Kindle so you might like to convert your PDF eBooks or documents to a more Kindle friendly format. Even though PDF is readable by the Amazon Digital Text Platform, you can make it better by optimizing text size, and a larger readable layout. ( Image courtesy gillyberlin )
Of the many PDF or Kindle converters, Kindle/PDF (K2PdfOpt) is one. It stands out for intelligent cropping and its batch processing features.
K2PdfOpt just doesn’t do a simple conversion; it maximizes the reading area of a PDF file and makes readability better on the 6-inch Kindle screens. It converts the PDF file to a bitmap and then automatically maximizes the viewing area by cutting, cropping, and reassembling the viewable areas. It removes excess white space and intelligently repaginates the original file to improve flow. Note that it does not make the pages flow seamlessly or remove footers as in Kindle’s default AZW format.
K2PdfOpt handles PDF files with two-column layouts particularly well. It auto-detects two-column documents. The other notable feature is that it also preserves the original fonts and graphics without dithering them unlike many other converters.
The conversion process is fast and fully automatic. You can take a folder full of PDF documents and convert them into the Kindle friendly PDF format by the simple drag-drop process.The PDF Conversion – Just Drag ‘N Drop
Drag and drop a single PDF document or a folder to the K2PdfOpt icon.
The conversion process is fast and the new PDF files are saved same place as the originals with “_k2opt” at the end of the name of each.
Retaining the original feel of the graphics and fonts comes at a price because the bitmap method increases the final file size. But that’s a small price to pay for a better reading experience. The bitmap conversion also handicaps searching within the document.
These few cons aside, K2PdfOpt is one of the best tools available for making your PDF files more Kindle friendly.The above article may contain affiliate links which help support Guiding Tech.
