Generate realistic smoke overlays in your browser. Create plumes, clouds, and wisps with full control over density, turbulence, and color. Export transparent PNG up to 4K resolution. Free online tool.
Open Smoke GeneratorCreate stunning, realistic smoke effects directly in your browser with the FX Labs Smoke Generator. Whether you need a gentle wisp of cigarette smoke, a billowing plume rising from an explosion, or a dense atmospheric haze for cinematic compositing, this tool gives you complete control over every aspect of the effect. Adjust plume direction, width, length, curvature, and taper to shape the flow of smoke exactly how you envision it. Fine-tune turbulence with warp strength, scale, and octave controls to add organic detail and chaotic motion that looks physically plausible. The puff system lets you control particle count, size distribution, and opacity for anything from thin translucent vapor to thick opaque clouds. Choose between Smoke mode for directional plumes and Isolation mode for centered cloud formations perfect for product photography or portrait overlays. Every render is deterministic thanks to the seed system, so you can reproduce any result or iterate on a design with confidence. Export your smoke effects as transparent PNG files at resolutions up to 4K (3840 x 2160), ready to drop into After Effects, Photoshop, Premiere, DaVinci Resolve, or any compositing pipeline. Ideal for VFX artists, game developers creating particle textures, YouTube thumbnail designers, social media content creators, and photographers looking to add atmosphere to their shots.
Select Smoke mode for directional plumes or Isolation mode for centered cloud formations.
Adjust direction, width, length, curvature, and taper to control the overall flow of smoke.
Dial in warp strength, scale, and octave count to introduce organic detail and chaotic motion.
Set your resolution up to 4K, choose a transparent background, and export a production-ready overlay.
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.
