How do I make my screen fully white?

Select the white tile, then press Go Full Screen. Your browser fills the entire screen edge-to-edge with a pure white background (#FFFFFF). Tap anywhere or press Escape to exit.

Can I download a color as an image?

Yes. Choose a color, pick a size preset or type a custom width and height in pixels, then press Download PNG. You'll get a lossless, high-quality PNG at exactly that size, rendered in your browser — nothing is uploaded.

Will this work on my phone?

Yes — it works on any modern phone, tablet, or desktop browser. On iPhone Safari, allow full screen when prompted for the smoothest edge-to-edge result.

Does this drain my battery?

A black full screen typically uses less power on OLED/AMOLED screens since those pixels turn off. White or bright colors use more power, similar to normal bright browsing.

Fake Update Screen

You stand up from your desk to grab coffee, and when a coworker glances over, your screen shows Windows Update at 73% — "Please do not turn off your computer." That's the whole bit. This tool gives you three convincingly styled update screens: a Windows 11-inspired spinning circle with percentage, a macOS-style black-background progress bar, and a terminal full of scrolling `apt` and `systemd` output for the Linux crowd. Each one fills the screen, blocks keyboard input visually, and dismisses instantly with Esc. No one will actually think their machine is updating — but they'll pause long enough for you to enjoy the moment.

How to use

Pick a platform style — Windows, macOS, or Linux terminal.
Click Full Screen and step away from your desk.
Press Esc (or click the screen) to dismiss — the update was never real.

Is it illegal to prank someone with a fake update screen?

It's a harmless visual joke — the same as putting a sticky note over a webcam. Just don't use it to mislead someone into delaying real work, and definitely don't run it on a device you don't own.

Can the fake update screen be dismissed?

Yes — press Esc or click anywhere on the screen and the update screen instantly disappears. No key combinations are blocked permanently.

Which OS style is most believable?

The Windows-style spinning-dots update is the most universally recognized. macOS is great for creative workplaces. The Linux terminal scroll is best for tech-savvy audiences who'd recognize a fake `apt-get` output.
