Hello Linux Geeksters. As you may know, XnConvert is a free image convertion tool, developed by the XnSoft team (the creators of the XnViewMP app). It has support for the most popular image formats, including: JPG, PNG, TIFF, GIF, BMP, RAW, PSD, JPEG and OpenEXR.

Because of its basic image manipulation functions, it allows the user to easily modify the opacity or the color of the photos, add filters or different effects to the photos. The application excels at converting multiple images simultaneously. The latest version available is XnConvert 1.6.5.
XnConvert 1.65 includes the lib32z1 lib32ncurses5 lib32bz2-1.0 libqtwebkit4:i386 libraries so that there won’t be dependency issues on Ubuntu/Debian and derivatives.
In this article I will show you how to install XnConvert 1.6.5 on Ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr, Ubuntu 12.04 Precise, Linux Mint 17 Qiana, Linux Mint 13 Maya, Pinguy OS 14.04, Elementary OS 0.3 Freya, Elementary OS 0.2 Luna, Peppermint Five, Deepin 2014, LXLE 14.04, Linux Lite 2.0, Debian 8 Jessie and Debian 7 Wheezy.
Because it is not available via any repository or PPA, we have to download the xnconvert deb package from the project’s site and install it by hand. I prefer gdebi over dpkg due to the fact that it also handles dependencies.
How to install XnConvert 1.6.5 on 32 bit Ubuntu, Debian and derivatives:
$ sudo apt-get install gdebi
