XVDown - X Video Downloader

Download X (Twitter) videos & GIFs free and privately: vault storage, full history, and password lock.

XVDown helps users keep videos and GIFs from X (Twitter) on their own device — quietly and under their control. Timeline download: One control on video tweets. Picks the best MP4 bitrate automatically; multi-video posts download in one go. Private vault (default): Files stay in extension storage — not the system Downloads folder, download shelf, or chrome://downloads. Export only when the user chooses. Full history: Author, text, time, resolution, and engagement stats are searchable, filterable, sortable, and exportable as JSON or CSV. Access password: Optional lock on the history page; the password hash is stored locally and never sent to us. English & 中文: Popup, history, and on-page toasts share one language setting. Completely free: All features are available without subscriptions, purchases, license keys, or account activation. There are no download quotas or history limits. XVDown 帮用户在浏览 X（Twitter）时，把视频和 GIF 安静地保存在自己的设备上，并由用户自行控制。 时间线下载： 在带视频的推文操作栏点击下载，自动选择最高画质 MP4；多视频推文一次完成。 私密保管库（默认）： 文件保存在扩展内部，不出现在系统下载文件夹、下载栏或 chrome://downloads；需要时再由用户手动导出。 完整记录： 作者、文本、时间、分辨率和互动数据可搜索、筛选、排序，并可导出 JSON 或 CSV。 访问密码： 可选的记录页密码锁；密码哈希只保存在本机，不会发送给开发者。 中英切换： 弹窗、记录页和页面提示共用同一语言设置。 完全免费： 无订阅、无购买、无激活码、无账号激活；没有下载次数限制，也不限制历史记录数量。
