About Abstract Header Generator
What It Does
Creates abstract layered header images by stacking translucent colored bands over a solid background. Each generation produces a unique composition — no two images are the same. Perfect for blog posts, social media banners, and page headers where you need something visually interesting without hiring a designer or using AI image generators.
Features
- 10 preset palettes — Sunset, Ocean, Forest, Midnight, Candy, Monochrome, Autumn, Arctic, Earth, and Neon. Or build your own with 2-8 custom colors.
- 3 curve styles — Flowing waves (smooth bezier curves), diagonal bands (geometric stripes), and organic blobs (amorphous shapes).
- 6 size presets — Blog/OG Image (1200×630), LinkedIn Banner (1584×396), Notion Page Banner (1500×300), Twitter/X Header (1500×500), YouTube Thumbnail (1280×720), or any custom dimensions up to 4000px.
- Save & load — Save the full layout (curve geometry + colors + settings) as a JSON file. When loading, choose to restore everything or just the layout while keeping your current palette.
- Dual export — PNG for immediate use in any platform, SVG for infinite scaling and further editing in design tools.
- Adjustable layers — Control how many overlapping bands to generate (3-12).
