A Falling Snow Effect for Your Whole Screen
The Snowfall Effect is an interactive fullscreen snow simulation that brings a calm winter atmosphere to your screen. Hundreds of snowflakes drift and swirl across hand-built scenes, from a quiet night sky to glowing village windows, with no images to download and nothing to install.
Every flake has its own size, speed, and drift. Larger ones render as detailed six-armed crystals that slowly rotate, while smaller ones float as soft glowing circles. Move your mouse or finger to push snowflakes aside, and watch them pile into smooth mounds at the bottom of the screen.
You control the intensity, wind, background scene, and ground accumulation, so you can dial in anything from a gentle flurry to a full blizzard.
How to Use the Snowfall Effect
Choose a scene
Pick a background from the scene bar: Night Sky, Aurora, Pine Forest, or Village. You can also use Upload Background to set your own photo as the backdrop.
Set the intensity
Use the snowflake slider to move between Light, Moderate, Heavy, and Blizzard, from a thin flurry up to a dense storm of flakes.
Adjust the wind
Drag the wind slider left or right to change direction and strength. The center is Calm, while the extremes push the snow sideways into a driving gust.
Toggle accumulation and timer
Turn on Accumulation to let snow pile up along the bottom, or set a sleep Timer (30, 60, 90, or 120 minutes) to fade the snow out automatically. Move your mouse over the snow to push nearby flakes away.
Features
Realistic Snowflakes
Flakes come as soft glowing circles plus larger six-armed crystals with branches, each with its own size, speed, opacity, and wobble for a varied, natural look.
Four Built-In Scenes
Choose Night Sky, Aurora, Pine Forest, or Village. Each scene is drawn with pure CSS gradients, so there are no images to load.
Custom Background Upload
Upload any photo as your backdrop. It is blurred and darkened automatically so the falling snow stays clearly visible on top.
Four Intensity Levels
Step from Light to Moderate, Heavy, and Blizzard, scaling the snow from roughly 80 flakes up to a dense 600-flake storm.
Adjustable Wind
Set wind strength and direction from a calm fall to strong gusts that blow the snow sideways across the screen.
Ground Accumulation
Snow that reaches the bottom builds into smooth mounds rendered with bezier curves and a white-to-blue-grey gradient.
Mouse & Touch Interaction
Move your cursor or finger across the screen and nearby snowflakes scatter away, creating an organic ripple wherever you point.
Sleep Timer
Set a 30, 60, 90, or 120-minute countdown and the snow gradually fades out and pauses, with a badge showing the time left.
Auto-Hiding Controls
The control bars fade away after a few seconds of inactivity for a clean fullscreen view, then reappear the moment you move or touch.
Saved Preferences
Your intensity, wind, scene, and accumulation settings are stored in your browser so the snowfall resumes just how you left it.
Frequently Asked Questions
How do I make snow fall on my screen?
Just open the page and the falling snow effect starts on its own. Pick a scene, then use the sliders to set the intensity and wind. There is nothing to download or install.
Can I run it full screen as a screensaver?
Yes. The effect fills the whole screen and the controls auto-hide after a few seconds, so it works well as an ambient background. Set a sleep timer if you want it to fade out and stop on its own.
Does it work on phone and desktop?
Yes. The snowfall is fully responsive and supports touch, so you can push flakes with your finger and reach every control on a smaller screen. On phones the flake count is trimmed automatically to keep the animation smooth.
Can I adjust the snow speed and density?
Yes. The intensity slider sets how many flakes fall and how fast, across Light, Moderate, Heavy, and Blizzard. The wind slider then controls the sideways drift, from calm to a driving gust.
Why do some snowflakes look like stars?
Larger flakes have a chance to render as six-armed crystal shapes with small branches instead of plain circles. This adds variety and a more realistic snowflake look to the heavier settings.
Will my settings be saved?
Yes. Your intensity, wind, scene, and accumulation choices are stored in your browser's local storage and restored on your next visit. A custom uploaded background is used only for the current session and is not saved between visits.
Does this tool upload any data?
No. Everything runs in your browser. A background image you upload is processed locally and never sent to any server, and no usage data is collected or tracked.
