YouTube Conv.axs is an open-source media downloader by Jan Sixta that extracts audio and video streams from YouTube. Built upon the NewPipe Extractor framework, it provides a straightforward way to save content for offline listening or viewing without the need for proprietary services. The application handles the fetching of available streams and packages them into common file formats, embedding relevant metadata and album art where applicable.
Version 3.17.0, made available in mid-October 2026, continues to refine the core experience. While the developer does not provide a specific public changelog for this release, the consistent update pattern from previous versions like 3.16.2 and 3.16.1 suggests ongoing improvements to stream extraction reliability and the stability of the download engine. The app remains a lightweight option, with the APK file staying at a compact 12 MB.
Regarding privacy, this tool operates entirely on-device. It does not route requests through external proxy servers for downloading, as it leverages the NewPipe Extractor to parse YouTube's public pages directly. This means your search queries and download selections are not tracked by a third-party service associated with the app. The only network connections made are to YouTube's servers to fetch the stream data, without an intermediary collecting your watch history.
