Why Netflix Downloader

为什么选择Netflix Downloader

Netflix streams all of its content through encrypted adaptive bitrate delivery, which means there is no straightforward way to right-click a video and save it as a file. The official mobile apps offer a limited offline download feature, but it locks those files inside the Netflix ecosystem, and the web player provides no download capability at all. Users who want a permanent local copy of a film or episode they are paying to access have no native option for doing so.
Netflix Downloader is being designed to integrate directly with the browser and work alongside the Netflix web player. The goal is to detect active video playback in the current tab, present available quality options, and produce a standard MP4 file that you can store on your hard drive and watch on any device without needing a network connection or an active subscription session.
Netflix通过加密的自适应码率传输方式分发所有内容，这意味着你无法直接右键点击视频将其保存为文件。官方移动应用提供了有限的离线下载功能，但这些文件被锁在Netflix生态内，而网页播放器完全没有下载能力。想要将自己付费观看的电影或剧集永久保存到本地的用户，没有原生的实现途径。
Netflix Downloader设计为直接与浏览器集成，和Netflix网页播放器协同工作。它的目标是检测当前标签页中正在播放的视频，提供可选的清晰度选项，生成标准的MP4文件，你可以将其存储在硬盘上，在任何设备上观看，无需网络连接或有效订阅会话。

About Netflix

关于Netflix

Netflix is the world's largest streaming service, offering a vast catalog of movies, TV series, documentaries, and award-winning original productions across nearly every genre. Its web player delivers high-quality video through the browser but does not include any built-in file export or local save functionality beyond its own mobile offline mode. Netflix Downloader is being built to fill that gap for subscribers who want a standard video file they can keep on their own device and watch without depending on an active streaming session.
Netflix是全球最大的流媒体服务，提供几乎覆盖所有类型的海量电影、电视剧、纪录片和获奖原创作品。它的网页播放器通过浏览器提供高质量视频，但除了自身的移动离线模式外，没有内置任何文件导出或本地保存功能。Netflix Downloader的开发目的就是为想要获得标准视频文件、可以保存在自己设备上、无需依赖活跃流媒体会话即可观看的订阅用户填补这一空白。
