Extractify

A web-based media clipper for YouTube and SoundCloud. Paste a URL, pick a format, set your timestamps, and download exactly the clip you want — no need to download the full file and cut it yourself.

Built to solve a personal problem: wanting specific parts of kirtan or music from YouTube or SoundCloud without the hassle of downloading everything.

How it works

1. User pastes a URL and hits Fetch
2. The backend calls yt-dlp to extract all available formats
3. User selects a format and sets timestamps
4. On download, yt-dlp downloads only the selected section using --download-sections
5. ffmpeg merges video and audio (for video clips) and trims precisely with --force-keyframes-at-cuts
6. The file is served to the user and deleted from the server after 1 hour

All downloads are routed through a residential-adjacent proxy to avoid YouTube bot detection. Cookies are used as an additional layer of authentication.
