Computer Freeze Simulator

No. The tool only shows a fake frozen screen inside your browser tab. The computer keeps running normally underneath - press Esc at any time, or tap the Exit button on a phone, to get back to your desktop.

Cursor Trail leaves a frozen copy of the cursor wherever the mouse moves. Screenshot shows a still picture with no extra effects. Click Trail drops a red marker wherever someone clicks. Glitch adds random screen tearing. Ghost Cursor replaces the real cursor with one that lags and jumps, as if the computer can barely keep up.

Yes. Click Capture Screen, pick the window or screen to freeze, and the prank uses that picture instead of the fake Windows desktop. You can also upload a screenshot you already have. Screen capture works in desktop Chrome, Edge and Firefox. iPhone, iPad and most Android browsers cannot capture the screen from a web page, so take a screenshot with the device buttons and upload it instead.

No. The capture or upload stays in this browser tab on your device. It is never sent to a server, never saved and never put in a share link. Screen sharing stops as soon as the single picture is taken, and closing the page discards it.

Every time the user moves the mouse, a copy of the cursor stays on screen at that position - making it look like the cursor is multiplying instead of moving. After a few seconds, the screen fills with frozen cursors.

The beeps are synthesized in your browser using the Web Audio API - they sound like a computer that has stopped responding to input. No audio files are downloaded or played from your system.

Press the Esc key. On a phone or tablet, tap the screen and then tap the Exit button that appears. If Hold ESC to Exit is enabled, hold ESC or the Exit button for one second. The exit is always available - the computer is never actually locked.

Yes. Set a delay of 5 to 60 seconds before the freeze starts, giving you time to step away from the computer before the prank begins.

Yes. The freeze runs in iPhone Safari, Android Chrome and any modern mobile browser, and finger movements and taps are tracked like a mouse. Use Upload Screenshot for the background, because phones cannot capture the screen from a web page. iPhone Safari does not let web pages go fullscreen, so the browser bars stay visible there.

Yes. Your last settings are saved in this browser only and come back the next time you open the page. A shared link always opens with the settings it was made with. Screenshots are never remembered.

No. Nothing is installed and no settings are changed. Once you press Esc and close the browser tab, everything returns to normal immediately.
