Generate realistic fire and flame overlays in your browser. Create campfires, torches, and bonfires with full control over turbulence, color, and intensity. Export transparent PNG up to 4K resolution.
Open Fire GeneratorGenerate procedural fire and flame effects with the FX Labs Fire Generator, a tool that creates physically-inspired flames directly in your browser. Shape your fire with width, height, taper, and base position controls to produce anything from a narrow candle flame to a roaring bonfire. The turbulence system uses multi-octave fractal noise with adjustable warp intensity and scale to create the organic flickering and dancing motion that makes fire look alive. Control the fill density to determine how solid or transparent the flame body appears. Temperature-based coloring gives you independent control over the bright core and cooler outer edges of the flame, with an intensity multiplier for overall brightness. The integrated smoke system adds wispy smoke tendrils rising above the flame with separate density, rise speed, and spread parameters, so you get a complete fire-and-smoke effect in a single render. The flicker control introduces the random brightness variations that make fire feel dynamic even in a still image. Every render is seed-based for perfect reproducibility. Export your fire effects as transparent PNG overlays at up to 4K resolution, ready for compositing in After Effects, Photoshop, Nuke, or any video editor. Perfect for campfire and torch overlays in film production, game asset creation, social media graphics, Halloween and horror themed content, and any project that needs convincing procedural flames.
Control width, height, taper, and base position to create anything from a candle to a bonfire.
Use multi-octave fractal noise with warp controls to create organic flickering and dancing motion.
Adjust core and edge temperatures for realistic coloring and enable the integrated smoke system.
Select up to 4K resolution, enable transparency, and download your fire overlay.
The Fire Generator can produce a wide range of flame effects including candle flames, campfires, torch fire, bonfires, and abstract flame shapes. Adjust width, height, taper, and turbulence to control the overall form, and use temperature controls to set the color palette from deep red embers to bright white-hot flames.
Yes. The Fire Generator has a built-in smoke system with separate controls for smoke density, rise speed, and spread. This produces realistic wispy smoke tendrils above the flame without needing to composite a separate smoke layer, giving you a complete fire-and-smoke effect in a single render.
Yes. Set the Background option to "Transparent" to export a PNG with the fire and smoke visible on a fully transparent background. This is ideal for overlaying fire effects onto footage, photos, or game scenes in any editing or compositing application.
Core Temp controls the color of the hottest inner part of the flame, with higher values producing brighter yellow-white. Edge Temp controls the cooler outer edges, with lower values creating deeper orange-red tones. Together they define the thermal gradient that makes fire look realistic.
You can export at 720p (1280x720), 1080p (1920x1080), 1440p (2560x1440), or 4K (3840x2160). The procedural nature of the rendering means the fire looks sharp and detailed at any resolution without pixelation or scaling artifacts.
Flicker introduces random brightness and shape variations across the flame body, simulating the natural dancing movement of real fire. Higher flicker values create more dramatic variation between bright and dim areas, making the flame appear more dynamic and alive even in a still image.
Absolutely. Export fire effects as transparent PNG files and use them as sprite textures, particle system sources, or UI elements in Unity, Unreal Engine, Godot, or any game engine. The deterministic seed system lets you generate consistent asset sets with matching visual style.
For a natural campfire, use moderate Width (0.3-0.4), Height around 0.5-0.7, Taper at 0.5-0.6, and Base Y at 0.1-0.15. Set Core Temp high (0.85+) and Edge Temp low (0.2-0.3). Enable smoke with moderate density and rise. Use 5-6 octaves of turbulence for organic detail.
