Run classic and modern screensavers directly in your browser. Choose a style, customize the motion and appearance, then launch it fullscreen.
The UtilityGlen Online Screensaver Simulator turns your browser into a customizable animated display. Bounce a colorful DVD logo, show a minimal flip clock, recreate a retro No Signal screen, run cascading Matrix-style code, fly through a starfield, revive neon Mystify geometry, or let the entire screen breathe smoothly through RGB color palettes.
Each screensaver runs directly inside the page and can be adjusted in real time. Choose a mode, change its speed or appearance, then switch the preview into fullscreen when you want the animation to take over the display.
Instead of opening a different webpage for every effect, this screensaver simulator combines several distinct visual styles into one interface.
You can switch modes immediately, adjust the settings that matter for that particular screensaver and use fullscreen mode when you want the browser tab to become the display.
Go from retro television graphics to digital rain, calm color transitions, space flight or classic computer screensaver nostalgia without leaving the page.
The interface only shows relevant options. Adjust Matrix density, DVD logo size, clock preferences, analog texture or Color Breath palettes without unnecessary clutter.
Preview everything inside the tool first, then expand the active screensaver to fill the browser display when you are happy with the settings.
Stop motion when needed, restore the defaults or let Randomize quickly produce a different combination of supported settings.
Every mode has its own character. Some are playful, some useful, some nostalgic and some are designed simply to make an idle screen look great.
A colorful DVD-style logo moves continuously around the display, reversing direction when it reaches an edge and changing color as it bounces.
Turn your screen into a large minimalist clock showing the current device time. Select 12-hour or 24-hour display and optionally show seconds and the date.
A stationary television test-bar display with a centered No Signal message. Enable the optional analog texture when you want a slightly rougher broadcast look.
Falling symbols move through vertical columns over a black background while previous glyphs gradually fade, producing a classic digital-rain appearance.
Stars move outward from the center to create the illusion of flying forward through space. Increase density for a busier star tunnel or adjust the speed.
Neon polygon outlines move around the display, rebound from the edges and build colorful geometric trails inspired by classic desktop screensavers.
Color Breath smoothly transitions the whole display from one color to the next. Choose a classic rainbow, RGB primaries, neon colors, pastel shades, sunsets, ocean blues, forest greens, fire tones, icy colors, candy palettes, cyber colors, warm or cool flat colors, earth tones, monochrome, or a completely custom static color.
Transition styles include a pure flat fade, soft breathing illumination, radial color movement and horizontal or vertical blends.
Color Breath is designed for people who want something calmer than bouncing shapes or falling characters. Instead of moving objects around the display, the screen itself becomes the animation.
Colors transition gradually using smooth interpolation, and you can keep the experience simple with a flat full-screen fade or add subtle visual depth through breathing, radial and directional gradient styles.
There is no setup wizard. The whole experience happens directly inside the tool.
Select the screensaver card that matches the look you want.
Change speed, scale, density, color or mode-specific options.
See your changes immediately without reloading the page.
Expand the active screensaver to fill the browser display.
Screensavers are not limited to a desktop PC. Any setup that can display a browser can potentially become a clock, ambient color panel, retro display or animated background.
Give an otherwise unused screen a clock, color display or animated visual.
Use fullscreen mode to turn a large screen into a decorative visual.
Flip Clock can turn a spare display or tablet browser into an oversized clock.
Color Breath is ideal when you want smooth full-screen color rather than busy motion.
Add a colorful or nostalgic display behind a desk, product shot or camera setup.
DVD Bounce, Mystify and No Signal can add a nostalgic touch to old-school setups.
An online screensaver is a webpage that displays an animation, clock, pattern or other visual that can remain on screen without installing traditional operating-system screensaver software.
A browser-based screensaver is especially useful when you want something temporary: open the page, select an effect, switch to fullscreen and close the tab when you are done.
The screensaver effects are generated directly by the webpage using browser technologies including HTML, CSS and canvas graphics.
Because the effects are generated live rather than played as prerecorded videos, settings such as animation speed, object size, density and colors can update immediately.
