K2pdfopt is a powerful tool which can optimise PDF and DJVU documents for reading on mobile devices (e-readers, tablets, smartphones).

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.
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). Just drag and drop your PDF/DJVU file icon onto the k2pdfopt icon to convert it. You will be prompted for conversion options (as of v1.16). K2pdfopt GUI is, as the name hints at, a graphical user interface for k2pdfopt.It was developed to help you easily transfrom your PDF and DJVU files to particular formats that can be used on e. 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. 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.
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.
Verdict:
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.
Hi Marja,
K2pdfopt For Macbook
According to the developer's site, the last version (2.4.2) of k2pdfopt was built in May 2017 for macOS which predates the release of macOS 10.12.6 (your profile) or any High Sierra release. The segmentation fault is caused by an application attempting to access restricted memory space, and the operating system stopping this attempt.

The resolution of this issue is that the developer needs to fix bad behavior in his application, and recompile/release it as an updated version. You cannot fix it by tweaking the operating system.
