k2pdfopt GUI

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-readers.
An important aspect you should keep in mind is that this software application does not require installation, and therefore the Windows registry and Start menu/screen are not going to suffer any changes. After its removal, no leftovers will remain behind.
Aside from that, by dropping the program files to a USB flash drive, it is possible to run k2pdfopt GUI on any computer you can connect to, just by clicking the executable.
This utility can be used by anybody, regardless of their previous experience with the IT world, as its interface sports a simple and intuitive interface. It is split into two panels: one enables you to view all added documents, while the other presents all the available settings.
PDFs and DJVUs can be uploaded by clicking the “Add” button or by using the “drag and drop” function. You can choose between several configuration profiles, suitable for several models of Kindle, Kobo and Nook e-readers.
It is also possible to tinker with all the options manually, and thus auto straighten pages, break pages, control the gamma levels and DPI resolution, change the margin dimensions, text justification, vertical and word spacing, and select particular pages to convert. You can enable GOCR or Tesseract OCR with custom visibility (text, source and box), while also inputting the maximum word height and number of columns to use.
In conclusion k2pdfopt GUI is a handy piece of software, which does not put a strain on your computer’s performance, presents a good response time, a user-friendly interface and enough options to keep you busy for quite a while.
