FAQ
Why are there black bars in fullscreen?
Press F11 to enter browser fullscreen mode (not the page's built-in fullscreen button). This hides the address bar and taskbar, ensuring the test covers your entire screen.
How do I go fullscreen on mobile?
Tap the test area to automatically enter fullscreen. Some mobile browsers may work best in landscape mode. We recommend Chrome or Safari.
Are the testing tools paid?
No. All ScreenTester.io testing tools are completely free — no registration, no downloads required. If you find them helpful, consider supporting us.
