Rain Draped Glass Effect

Water and condensation

This tool builds a procedural wet window filter directly over your image. It generates a fluid map containing condensation, small beads, and large teardrop streaks. By adjusting the rain volume and droplet mass, you can move from a sparse dewy surface to a heavy storm glass look.

Gravity and refraction

Gravity drag pulls the water downward, creating long wiped paths and active running trails. The tool also simulates a glass refraction effect, acting as a lens that bends and inverts the details behind each droplet. Higher refraction values create a stronger fisheye distortion inside the water beads.

Foggy backgrounds

The condensation setting controls the foggy glass effect behind the rain. High condensation produces a milky, misty background, obscuring the original scene. Rolling drops wipe clearer trails through this fog, mimicking a realistic photo through rain glass.

Cinematic combinations

A cinematic rain effect adds instant atmosphere to portraits, neon cityscapes, and night photography. To push the mood further, you might visit the best online tools for adjustable film grain or a dedicated grain effect website. While some users combine this with a 3d glasses effect online, applying a basic film grain filter online can be enough to complete the analog look.

Frequently Asked Questions

JPEG, PNG, and WebP. The downloaded image keeps the same format as your original file.

No.

Rain Volume controls how much water accumulates on the glass. Lower values create sparse droplets; higher values create a heavier wet-window look with more condensation beads and rain coverage.

Droplet Mass controls the physical size and weight of the water beads. Smaller values create fine droplets; higher values create larger drops with stronger lensing and heavier streak behavior.

Gravity Drag stretches droplets downward, creates teardrop shapes, and increases long wiping trails as water runs down the glass.

Refractive Index controls how strongly the water droplets bend and invert the image behind them. Higher values create sharper, more dramatic lens-like refraction.

Condensation controls the foggy background layer on the glass. Higher values blur and milk the image more heavily, while rolling drops wipe clearer trails through the fog.

Randomize Drops creates a new procedural droplet layout while keeping your selected rain, condensation, and refraction settings.

Yes. Once the page has loaded, the tool can work offline because the image processing happens fully in your browser.
