SaveXPost is a free online tool for downloading videos from X (formerly Twitter). Paste the link to any public post, choose the quality you want (HD up to 4K where the original supports it), and the video saves straight to your device as an MP4. It also turns Twitter GIFs into MP4 files. There’s no login, no watermark and no app to install. SaveXPost runs in your browser on iPhone, Android and desktop, and it’s built to be fast and private.
