Sometimes you can't install anything: a borrowed laptop, a locked-down work PC, or you just need to help someone right now. The ScreenSharePRO web app runs in the browser, with nothing to download.
How do I control a Windows PC from a browser?
- On the PC you want to reach, run the ScreenSharePRO desktop app and note its Your ID and Password, or a session code.
- On your device, open the web app in a current version of Chrome, Edge or Firefox.
- Enter the ID or session code and the password, and connect.
You see the PC's screen live, and if the person at that PC allows it, you can use its keyboard and mouse. You can switch between fit-to-window and fullscreen, and record the session (the browser saves a .webm file).
Can I share my own screen from a browser?
Yes, from a desktop browser: open the web app and select Share Screen. A screen shared from a browser is view-only: viewers can watch, but browsers can't give anyone control of your keyboard and mouse. Mobile browsers can't share their screen at all.
What needs the desktop app?
These need the ScreenSharePRO desktop app, at one or both ends:
- Copying text, images and files between the two computers (desktop app at both ends)
- Switching between the host's monitors during a session
- Sending system keys such as the Windows key and Alt+Tab
- Original size, one remote pixel to one local pixel
- Saved hosts with stored passwords
- Waking a sleeping PC with Wake-on-LAN
- Using the keyboard and mouse of the shared screen: only possible when that screen is shared from the desktop app
The full comparison is in the "What works where" table on the downloads page.
Why won't the browser connect when the desktop app does?
The web app connects directly only, without the relay the desktop app falls back on. A strict firewall or VPN between the two computers can block that direct path. See which firewall ports ScreenSharePRO needs.
