K2pdfopt is a powerful tool which can optimise PDF and DJVU documents for reading on mobile devices (e-readers, tablets, smartphones).
I need to print a form, which is in some sort of hardcore PDF document container that won't let itself t be saved as a PDF using the standard print dialog because it appears to be intentionally 'locked down' by Adobe Acrobat DC, which is the only PDF reader that appears to read the document format. Pdf k2pdfopt rearrange reflow. Reading PDF with Kindle has been endlessly spit by friends. In the era when Kindle can still escape, we have excellent Kindle third-party plug-ins such as Koreader to realize real-time rearrangement of PDF documents, but with the Kindle firmware version The frequency of upgrades speeds up, and jailbreaks can no longer keep up, so third-party plugins such as. If k2pdfopt is terminating abnormally (crashing) when you run it, try one of the 'Older CPU' downloads below. They run approximately 20% slower than the optimized 32-bit downloads above, but they are compiled for more generic i386 CPUs with less aggressive optimizations. V2.53 (July 18, 2020).
This isn't a matter of cutting resolution, or applying other basic tricks. K2pdfopt makes far more intelligent use of your reading space by trimming white space, cutting and cropping documents, reflowing text, then reassembling everything to fit the smaller viewing area.
OCR abilities (via Tesseract) means the program can even work with scanned pages. It's able to identify text, reflow it, and then add an OCR layer to the finished document. Not only will this mean it'll be easier to read the pages on a small screen, but your document will also become searchable.
While this sounds complicated, the program can be surprisingly easy to use. Drag and drop multiple documents onto the program, choose your target device (or set page width, height and dpi manually), and use the Preview button to inspect the results. If you're happy, click 'Convert All Files' and wait as the mobile-friendly versions are produced.
If the default settings don't deliver what you need, life can be a little more complicated, as there are a lot of options to consider. Should the 'Conversion Mode' be 'default', 'copy', 'trim', 'fitwidth', 'fitpage', '2-column', 'crop'...? You can find out just by trying a new setting and previewing the results, but it can take some time to find out what works best.
Don't let this put you off trying the program, though. We found k2pdfopt usually delivered great results, and as it's open source there are no adware or other hassles to worry about: it's completely safe to install and use.
Smart, easy to use and very configurable, K2pdfopt is an excellent tool for anyone who regularly needs to view desktop-oriented PDFs on a small screen.
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.
