About Us

We are a professional software team specialized in developing file 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 source/target file formats. Formerly users need to go to corresponding category to set options and convert files.

Please note CDKM.com removed support for outdated browsers such as Internet Explorer 6-8, Opera 12.1x or Safari 5.1+ etc., so we recommend to use our old website if you are not using a modern browser.

Experimental

We are working on building offline converter (opposite to online converter) running in web browser. However, this new technology is not supported or not fully supported by many web browsers yet, so it's only an on-going experimental project and not released yet. Please check back later for more information.

Privacy

We do not provide REST API, account signup and long-term file storage (includes connections to third-party file storage such as Google Drive, Dropbox or OneDrive etc.) because of potential GDPR (General Data Protection Regulation) concern. For detailed information of our privacy policy, visit https://cdkm.com/privacy.html.
