How it works
From browser tab to TV in three steps
CastBrowser analyzes the active tab only when you use the extension, then presents the compatible media it finds.
- 1
Open a webpage containing a compatible, non-DRM video.
- 2
Select the CastBrowser icon in your Chrome toolbar.
- 3
Preview, download, or choose a Google Cast device to watch on TV.
Designed for compatible, non-protected video
Protected or DRM-encrypted services are not supported, including YouTube and major subscription streaming platforms. Downloading is available for supported direct MP4 and WebM files; HLS streams can be detected for compatible playback and casting. Only download media you own or have permission to save.
