Getting Started with ROSI

Learn how to download media with ROSI: paste a URL, select download profiles, drag-and-drop queue items, and manage settings.

Install ROSI

Download the latest build for your platform from the ROSI downloads page or the Microsoft Store. Official installers bundle yt-dlp and FFmpeg, so no separate dependencies are required. Windows binaries are signed via Azure Artifact Signing.

Download a video or audio file

Open ROSI and paste a supported URL into the address bar, or drag and drop URLs directly into the queue textarea.
Select your desired Download Profile in Settings (Best video, Audio-only, or Custom quality presets).
Choose your download folder, or enable the Ask every time setting to select a destination on each run.
Press Ctrl/Cmd + Enter or click Download to start. Track progress in the queue section.

Queue & UI Controls

Collapsible Queue: You can expand or collapse the queue section using the arrow controls or arrow keys to save vertical screen space.
Flat UI: Toggle between the standard UI and the Flat UI using the toggle switch located on the main sidebar.
Close Confirmation: Active downloads trigger a confirmation prompt before closing to prevent accidental progress loss.

Browser cookies (when needed)

Some sites require cookies from your browser. Enable Hook into Web Browser in Settings and select a supported browser. See the Browser Cookies guide for platform details.

Updates

ROSI checks GitHub for new releases and downloads updates in-app. You can also download new releases manually at any time.

Custom FFmpeg path

Official builds include FFmpeg binaries. If you are building from source or prefer your own binary, set a custom FFmpeg path in Settings to override the bundled copy.
