YouTube HD Downloader is a Windows desktop app for downloading video or audio through a graphical interface. You can choose a single video, a playlist, or audio only, and check which qualities a video offers.

Features include video details, subtitle options, cancelling a download, and opening the download folder. You can set up FFmpeg from inside the app to merge video and audio and to convert formats.

What you buy is the built .exe file. Source code is not included. The app needs an internet connection, and FFmpeg must be available or configured in the app settings.

Available formats, qualities, and subtitles depend on the video source. Site support may change as platforms and downloader components update. Use it only for your own content or content you have permission to download.
