Vidsy is a Chrome extension designed to simplify the process of downloading video and audio content from a wide range of websites. It automatically detects various streaming formats, including HLS and DASH, allowing users to download files locally without needing accounts or tracking. Vidsy supports downloading high-quality streams, merging separate video and audio tracks, and extracting audio from videos with just a click. The user-friendly interface includes side panel and popup views, making it easy to monitor download progress, even for large files.

Privacy is a key feature of Vidsy, as it operates without collecting any user data and runs entirely within the browser, ensuring that no information leaves the user's device. The extension is open source, inviting contributions from the community while maintaining a commitment to user privacy. However, it does not support downloading DRM-protected content from platforms like Netflix or Disney+, adhering to legal restrictions.
