Mirror your Windows desktop to browsers with hardware H.264
Experience real-time desktop mirroring to any modern web browser using WebRTC and Windows Graphics Capture at up to 60fps. ScreenMirror, from Vasu Inukollu, is a Windows utilities tool for broadcasting a full desktop or a single display. It uses hardware-accelerated H.264 encoding and requires no receiver installation, offering low-latency viewing. The tool targets IT professionals, educators, and general users who need quick, local-network screen sharing for presentations or monitoring.
What does ScreenMirror do for local screen sharing?
ScreenMirror captures the Windows display and sends it to browsers via WebRTC. It uses the Windows Graphics Capture API to grab the desktop or a selected display, then encodes video with hardware H.264 before delivering streams to any WebRTC-compliant browser. The zero-client receiving side means viewers on Android, iOS, macOS, Linux, or desktop simply open a link to view the mirrored output.
Does it slow down your system during streaming?
CPU load is reduced by hardware encoding, shifting work to the GPU. The application uses hardware-accelerated H.264, which offloads encoding from the processor. That design lowers CPU usage compared with software-only encoders, and supports high frame rates up to 60 frames per second when the GPU and network permit. Actual impact depends on the host GPU and the number of simultaneous viewers present on the local network.
Is it safe to run on a production machine?
ScreenMirror operates as a local streaming host over the network, not a remote-control service. It shares screen pixels to browsers instead of opening remote control channels, which reduces the risk of remote registry or input changes. Use on trusted local networks is implied by its typical local-network operation; network topology and access control determine exposure when multiple viewers connect.
Do I need technical knowledge to install and operate it?
Installation and setup offer straightforward options for different users. The app can be deployed via an MSI installer or the Windows Package Manager command-line entry, providing a simple path for desktop users and a scripted path for administrators. Connecting viewers requires only a WebRTC-compliant browser, while advanced users can tune capture selection and frame-rate settings to match GPU and network capacity.
Works well for local, browser-based mirroring with one network trade-off
ScreenMirror is a practical tool for users who need quick, browser-accessible screen sharing on a local network. It minimizes CPU encoding by using hardware H.264 and avoids client installs on viewing devices. The main caveat is that the number and quality of simultaneous viewer streams scale with local network bandwidth, so plan topology and bandwidth if many viewers will connect.
