A small Windows desktop app for downloading videos you own, have permission to save, or that are legally reusable.

The app provides:

• A normal Windows .exe GUI with no terminal window.
• URL paste box, download folder picker, and progress log.
• Quality choices: 480p, 720p, 1080p, 1440p (2K), and best available.
• Output format choices: video as MP4 or MKV, and audio-only as MP3, M4A, WAV, or Opus.
• Built-in buttons to install or update yt-dlp and ffmpeg into a local tools/ folder.
• Multiple ffmpeg download sources, so one mirror failing does not stop setup.

Download the latest Windows build from GitHub Releases.

1. Download YT-Downloader-Windows.zip.
2. Extract the zip file.
3. Run YT Downloader.exe.
4. Click Install / Update Tools the first time you open it.

Use this app only for videos you own, have permission to download, or that are legally reusable. It does not bypass DRM, paid, private, or login-only restrictions.

This project uses the Windows .NET Framework compiler that ships with many Windows installs.
