About KUX Files

A .kux file is a video file saved in the Youku KUX format, a proprietary format used by Youku for downloaded videos from its streaming service. KUX files contain compressed video and audio designed for offline playback within the Youku application. The format was created to help manage video distribution and playback while limiting direct use outside the platform.

You may encounter .kux files when downloading videos from Youku for offline viewing, transferring archived media, or working with saved content from older streaming libraries. Users in regions where Youku is popular, as well as video archivists and media enthusiasts, sometimes handle these files when preserving or converting downloaded videos. Since the format is primarily intended for playback in the Youku app, converting KUX files to more widely supported formats is often necessary for viewing, editing, or sharing videos on other devices and platforms. However, you can open and play .kux files on FileHelper.com by dragging them to this page.
