Hi Marja,
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.

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.
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.
