YouTube 4K 视频下载器｜HSK下载

HSK下载 is an online service for parsing and downloading publicly available YouTube videos. Users paste a video link to view the actual available qualities, audio tracks, subtitles, and cover images provided by the source. It supports selection up to 4K resolution where available and operates as a web-based video download tool focused on YouTube content.

The service displays download tasks with progress, failure reasons, and completed files. Multiple tasks can run simultaneously. It extracts audio as MP3, saves subtitles and cover images separately after login, and returns credits for tasks that fail to create or process. Low-quality options from 360P to 720P and MP3 extraction consume credits, while 1080P, 2K, and 4K require an active VIP subscription in addition to credit consumption. High-resolution files are noted to play best in VLC, PotPlayer, or Infuse because some players such as Xunlei may fail with VP9 or AV1 codecs.

New accounts receive five download credits. No login is needed to preview parse results. Expired download links require re-parsing the original video to generate fresh tasks. The service stresses that only public content for which the user holds rights, has authorization, or that the platform permits may be saved, in compliance with source platform rules. It is delivered entirely through a browser interface with sections for online download, task management, packages, and support resources.

Packages provide credits along with VIP benefits such as access to higher resolutions and priority parsing during the validity period. All downloads deduct credits according to the chosen resource.
