Hi. This is the White Screen Flashlight tool.
It's a very simple idea. Sometimes you just need a bright, clean light on your whole computer screen. Maybe you're looking for something in a dark room. Maybe you need to signal to someone. Or maybe you just want a plain white screen for a moment.
Your phone has a flashlight, but your laptop or PC monitor doesn't. So I made this.
What This White Screen Flashlight Tool Is
It's exactly what it sounds like. You click a button, and your entire screen turns into a solid color—bright white by default. It goes full screen, covering your taskbar, your desktop icons, everything. It's just light.
But it's also a bit more. It's not *only* a white flashlight. You can change it to other colors. Red, green, blue, even black. So it's really a "full screen colored light" tool. But "white screen flashlight" is what most people search for, so that's what I call it.
It uses your monitor at its full brightness. So if you need maximum light in a pinch, this can actually help.
How to Use It (Super Simple)
The page loads with a simple control panel. You'll see some preset color buttons: White, Red, Green, Blue, Black.
White is the default and the main flashlight mode.
Just click the "White" button to select it. Then, click the big green button that says "Go Full Screen".
That's it. Your whole screen will fill with bright white light.
To turn it off, just press the ESC key on your keyboard. That exits full screen and brings you back to this page.
You can also click the "Black" preset and then go full screen if you need a pure black screen, like for checking monitor dead pixels or just having a dark display.
Using the Custom Color Picker
Below the preset buttons, there's a color picker. It looks like a little square.
You can click it to open a color wheel. Choose any color you want—light purple, soft orange, whatever.
When you pick a color, two things happen:
- The tool remembers that as your new "active" color.
- The info boxes update to show the HEX code (like #FF5733) and the RGB values (like 255, 87, 51) for the color you chose.
Then you click "Go Full Screen", and your whole monitor will glow in that exact color.
This is useful for more than just a flashlight. Artists sometimes use a solid color background to check contrasts. You could use a soft yellow as a mild night light. It's up to you.
Understanding the Display Info
There are two small info boxes below the color picker: HEX and RGB.
These just show the technical code for the currently selected color. Most people don't need this, but it's there if you do. If you're a designer or developer and you find a nice color you want to use elsewhere, you can copy the HEX code from here.
When you click "White", it shows #FFFFFF and RGB 255, 255, 255. That's just the computer's way of saying "pure white".
Why Would You Use This?
The main use is as a flashlight. Your laptop screen can be surprisingly bright. In a dark room, if you drop a small item (like an earring or a screw) on a dark carpet, turning on this white screen can light up the whole area near your laptop much better than a small phone light.
Finding a light switch in an unfamiliar dark room. Carry your laptop with the white screen on.
As a soft light for video calls. If your room lighting is bad, putting a soft, warm color (like a light peach) full screen on a second monitor behind your webcam can act as a crude fill light.
A black screen for checking for stuck pixels on your monitor or just giving your eyes a rest in a dark room.
As a simple signal. Need to get someone's attention from across a large office or house? A full screen bright red is hard to miss.
Honestly, sometimes I just use it to focus. A full screen of a calm color (like a very light blue) with no icons or text can help clear my mind for a minute.
Important Things to Know (Limitations & Tips)
This is a software tool. It can only make your screen as bright as your monitor's hardware allows. It won't make an old, dim monitor suddenly super bright.
It will use more battery on a laptop. A full white screen at max brightness is one of the most power-intensive things for an LCD screen. If you're on battery, use it sparingly.
For OLED screens (like on some high-end laptops and phones in tablet mode), be cautious with static bright colors for a very long time to avoid potential burn-in. A few minutes is perfectly fine.
The ESC key is your "off" switch. Remember that. It's the universal "exit full screen" command, and it works perfectly here.
The tool works in any modern browser (Chrome, Firefox, Edge, Safari). Just make sure your browser is allowed to go full screen (it usually asks for permission the first time).
A Note on Safety and Eyes
Don't stare directly at a full brightness white screen in a dark room for a long time. It can cause eye strain, just like any bright light.
If you're using it as a room light, maybe choose a slightly off-white or warmer tone from the color picker. It's easier on the eyes.
It's a tool, not a permanent light source. Use it sensibly.
Final Thoughts
It's a dumb little tool, but I've used it more times than I expected. When the power goes out and I need to find candles. When I drop a contact lens. When I just need a distraction-free blank canvas to think.
It's free, it's simple, and it does one job well. I hope you find it useful too, even if just once in a while.
Stay safe, and don't forget the ESC key to turn it off!
FAQs About the White Screen Flashlight
Does it work on a desktop PC with a monitor?
Yes, absolutely. It works on any computer with a web browser—desktop PC, laptop, all-in-one, even a tablet if you use desktop mode. The screen will fill with your chosen color.
Can I use it on my phone?
You can open the webpage on your phone's browser, but it won't be as effective. Phone screens are small, and they already have dedicated flashlight apps that use the much brighter camera LED. This tool is really designed for the bigger screen of a laptop or desktop monitor.
Why does it sometimes ask for permission to go full screen?
That's a standard browser security feature. Websites can't take over your entire screen without your consent. The first time you click "Go Full Screen" in a browser, it will pop up a message asking if you allow it. Click "Allow". After that, it usually remembers your choice for this site.
Can I adjust the brightness of the white screen?
Not directly within the tool, no. It sends pure white (255,255,255) to your screen at its maximum for the current brightness setting. To make it dimmer, you need to lower your monitor or laptop's physical brightness controls using its buttons or keyboard shortcuts (like Fn + F5/F6).
Is there a keyboard shortcut to activate it without clicking?
Not currently. You have to click the "Go Full Screen" button with your mouse. I kept it simple to avoid complicated instructions. Once it's full screen, ESC is the only shortcut you need.
Will it work if my internet disconnects?
Yes! Once the page is fully loaded in your browser, the tool works completely offline. You can disconnect your Wi-Fi, and you'll still be able to turn on the white screen and go full screen. You just need the internet to load the page the first time.
