About Us

We are a professional software team specialized in developing converter software, apps and websites for over 20 years. We have run a large converter website for more than 7 years. During this period, we have many unrealistic ideas and experimental new technologies which are not suitable for the old website so we create a new one.

CDKM.com is our next-generation website built with many unrealistic ideas and experimental technologies. The most exciting thing is that we finally manage to put all kinds of file conversions and settings into one single webpage regardless of file formats. Formerly users need to go to corresponding category to convert files.

Please note CDKM.com removed support for outdated browsers such as Internet Explorer 10 and earlier versions, so we recommend to use our old website if you are not using a modern browser.
