Thunder Free 3D Icon

A chunky 3D lightning bolt with that split-second, storm-is-here shape. Use this Thunder icon in weather apps, energy dashboards, power outage alerts, charging states, or anything that needs a clear thunder symbol icon at a glance. It also works when you need a thunder icon png for UI mockups, and the black version reads well on light backgrounds. Free for commercial use, with credit required on the free plan.

The Thunder icon is a 3D render with soft studio lighting, gentle shadows and a silhouette that stays readable from a hero section down to a 48-pixel UI slot. It ships as a transparent-background PNG, so it drops in without masking or background removal.

Designers reach for it most in sustainability reports, gardening apps, weather widgets and outdoor-brand sites, and it suits green-tech, agriculture platforms, outdoor brands and conservation groups.

Sizes on offer are 1024, 512, 256, 128, 64, 32, 24 and 16 pixels, free for personal and commercial projects with a credit to Thridy. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
