How it works

Canvas rules behind this template

The renderer draws seeded vertical strokes with slight drift and varied opacity.

Line count and length set the amount of falling motion without animating the PNG.

Ink density keeps the rain inside the paper system and avoids noisy neon effects.

Tips

Quick ways to improve the PNG

Use long thin lines for quiet emotional panels.
Increase drift for a windier action feel.
Keep density moderate when the uploaded subject has dark hair or dark clothing.
