Back to the k2pdfopt home page


For those of you who are not fans of the command-line interface built into
k2pdfopt, or if you aren't satisfied with the MS Windows GUI in v2.x, the following graphical user interfaces (GUIs) are available:

from Jens Wallauer
Last update: v2.0.1.0, 22 June 2013

Wallauer's Windows GUI is feature rich and very compact (much more compact than k2pdfopt itself!), and continues to have features added with his latest 2.0 release. It requires you to install k2pdfopt separately and may require .NET Framework 4 to be installed on your PC. OCR support was added in v1.04. Visit Jens' page for more details.

from Adrian Zandberg
Last update: 26 Jun 2018

The reflower GUI runs in either Mac OSX or Windows and includes k2pdfopt, so you only have to download the one file, but you may have to install the Tcl/Tk framework (for OSX). It accesses a more limited number of k2pdfopt options than Wallauer's GUI.

Update June 2018: Zandberg has stopped hosting this on his site, so I have grabbed copies of: the last version of his Mac installer and his screenshot. The drawback to this is that it is integrated with an older version of k2pdfopt (not sure which one). Here is his github source site (where the installer link is broken).

OSX version
Windows version

MacReFlower gives Mac OSX another GUI option. It is tuned specifically for the kindle paperwhite and requires you to also download the k2pdfopt OSX binary and put it in your path (/usr/local/bin recommended).

Recommended to me in an e-mail, the screen shot at the right shows the 32-bit MS Windows version of k2pdfopt (v2.18) running in Wine 1.4 on Ubuntu 12. It works pretty well and allows you to take advantage of the integrated MS Windows GUI in Linux.

There is also a mobileread.com post on how to integrate this with calibre.

Journal2eBook is written in python and therefore provides a GUI for all three platforms. It previews the source file and allows you to graphically select margins.

(with help from Huang Xin)
Last udpate: 4 July 2013

Huang Xin has forked a version of KindlePDFViewer which runs on the Kindle 3 and DX (and others?) and uses k2pdfopt for text re-flow. There is a mobileread.com thread about the KindlePDFViewer on the Kindle 3, as well, a thread about the original KindlePDFViewer.

Support for other e-readers:
   KOReader (Kindle Touch and Paperwhite)
