A beautiful and simple YouTube video downloader built with C# and WPF. Download your favorite videos in different qualities with a nice cherry blossom themed interface!

• Download YouTube videos in multiple quality options (360p, 720p, 1080p, etc.)
• Download audio-only files in MP3 or M4A format
• Real-time download progress with speed indicator
• Beautiful cherry blossom themed UI with animated petals
• Queue multiple downloads at once
• Choose custom download location

• Windows 10 or later x64
• .NET 8.0 Runtime (download from Microsoft)
• yt-dlp (automatically downloaded on first run if missing)

This app uses yt-dlp under the hood to download videos. It's basically a pretty UI wrapper around yt-dlp with some extra features I added.

The app will automatically download yt-dlp on first run if it's not found. No manual setup needed!

src/
├── Windows/      - UI Windows (MainWindow, dialogs)
├── Models/       - Data classes (VideoInfo, FormatInfo, etc.)
└── Helpers/      - Utility functions (file operations, yt-dlp integration)

I organized the code into folders to make it easier to maintain. Still learning about proper project architecture but this works for now!

• Sometimes the progress percentage jumps around (yt-dlp does this, not my code!)
• The sakura petals animation might lag on older computers
• Sometimes it take long befor video start downloading

Things I want to add eventually:

• Playlist support (download entire playlists)
• Download history with search
• Subtitle downloading
• Multiple simultaneous downloads
• Themes (dark mode, different colors)
• Auto-update feature
• Portable mode (no installation required)

I'm still learning C# and WPF, so if you have suggestions or improvements, feel free to open an issue or PR!

• Language: C# 12
• Framework: .NET 8.0
• UI: WPF (Windows Presentation Foundation)
• Download Engine: yt-dlp
• JSON: System.Text.Json

No external NuGet packages required! Everything is built-in except yt-dlp.

Q: Is this legal?
A: This tool is for downloading videos you have permission to download. Please respect copyright laws and YouTube's Terms of Service.

Q: Why does Windows Defender flag it?
A: Sometimes unsigned .exe files trigger warnings. The app is safe - you can check the source code yourself!

Q: Can I download age-restricted videos?
A: Not currently. This is a limitation of yt-dlp when not logged in.

Q: Does it work with other sites?
A: Technically yes (yt-dlp supports many sites), but I only tested with YouTube. YMMV!
