About KUX files

A .KUX file is a proprietary video container format utilized by Youku, one of China's largest online video streaming platforms. When users download videos for offline viewing using the official Youku desktop client, the media is saved with the .kux extension.

The primary issue with KUX files is their severe vendor lock-in. Engineered as a DRM (Digital Rights Management) wrapper, KUX is essentially a heavily modified Flash Video (FLV) format with a unique header. This prevents the file from being read by standard media players or operating systems. You cannot open a KUX file in VLC, nor can you import it into video editors like Adobe Premiere Pro. Users are normally forced to use the bloated Youku PC client just to watch their downloaded content.

To regain control of your media, conversion is mandatory. For universal playback across smartphones, smart TVs, and web browsers, convert KUX to MP4. If you need to preserve the highest quality or archive the footage, convert to MKV. Drag and drop your KUX file here to analyze and convert it into a standard format - free, online, and without installing complex command-line tools.
