Features & Capabilities

Video Downloader for Chrome automatically detects and downloads videos from any website, supporting multiple formats including MP4, WebM, OGG, AVI, MOV, FLV, WMV, MKV, plus streaming protocols like HLS and DASH. It uses smart detection to monitor network requests, scan for video elements, and capture embedded videos from iframes and XHR/Fetch calls, with real-time detection of dynamically loaded content.

Designed with privacy in mind, it processes everything locally on your device with no data collection or external servers, and is open source. The extension offers a clean popup UI, a badge with the detected video count, one-click downloads, URL copy, and displays file size and detection time. It is ideal for downloading educational content or tutorials you have permission to save for offline viewing. Note: some videos may be DRM-protected and cannot be downloaded; respect copyright and terms of service.

Is Video Downloader Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Video Downloader requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
