Create transparent smoke overlay PNGs for Photoshop, After Effects, and video compositing. Generate realistic smoke overlays with customizable density, direction, and turbulence. Free online tool.
Open Smoke GeneratorGenerate high-resolution smoke overlay PNGs with full transparency, ready to layer over your photos and video footage in any editing application. Unlike static stock overlays that force you to settle for a close-enough match, our generator lets you shape the exact density, direction, and turbulence of the smoke to fit your scene perfectly. Export at resolutions up to 4K and drop the result straight into Photoshop, After Effects, Premiere, or DaVinci Resolve with zero cleanup required.
FX Labs exports smoke effects as PNG files with full alpha transparency. PNG is the ideal format for compositing overlays because it preserves transparency data without compression artifacts, making it compatible with virtually every editing application including Photoshop, After Effects, Premiere Pro, and DaVinci Resolve.
Yes. Set the Background option to "Transparent" in the Output section and export your render. The resulting PNG will have a fully transparent background with only the smoke visible, ready to layer over photos, video frames, or other artwork in any compositing application.
You can export at four resolutions: 720p (1280x720), 1080p (1920x1080), 1440p (2560x1440), and 4K (3840x2160). The preview renders at lower resolution for fast feedback, then the export renders at your chosen full resolution for maximum quality.
The seed is a number that determines the exact arrangement of every puff and turbulence pattern in your smoke effect. Using the same seed with the same parameters will always produce an identical result. Change the seed to get a completely different variation while keeping all other settings the same.
Yes. All effects generated with FX Labs are yours to use in any personal or commercial project. There are no watermarks, no attribution requirements, and no licensing restrictions on the rendered output. You own the images you create.
Smoke mode generates a directional plume that flows from a source point in a specific direction, ideal for exhaust, chimney smoke, or breath effects. Isolation mode creates a centered cloud formation without directional flow, making it better for product photography backdrops, portrait overlays, and abstract atmospheric effects.
FX Labs works in all modern browsers including Chrome, Firefox, Safari, and Edge. A dedicated graphics card is recommended for faster rendering at higher resolutions, but integrated graphics will work for standard 1080p exports. Mobile browsers are also compatible.
For photorealistic smoke, increase the puff count to 800 or more, keep puff opacity low (around 0.03-0.06), and use moderate warp strength with high octave counts for fine turbulence detail. Adjust edge breakup to around 0.5-0.7 for natural dissipating edges, and use the softness control to blend puffs smoothly together.
