Generate SVG Blobs - Free Organic Shape Generator Tool

SVG blobs are organic, abstract shapes perfect for modern web design. They add visual interest to backgrounds, hero sections, and decorative elements. Our generator makes it easy to create unique, scalable blob shapes with just a few clicks. Here's your complete guide:

What Are SVG Blobs?

SVG blobs are smooth, organic shapes created using mathematical curves (Bézier curves). Unlike geometric shapes, blobs have an irregular, natural appearance that adds a modern, playful touch to designs. Because they're SVG (Scalable Vector Graphics), they remain crisp at any size and have tiny file sizes.

Getting Started

1. Click Randomize: The easiest way to start is clicking the "Randomize Shape" button. This generates a completely new blob with random curves and points. Keep clicking until you find a shape you like as a starting point.
2. Adjust Complexity: Use the complexity slider to control how many points (corners) your blob has. Fewer points (3-4) create simple, smooth shapes. More points (8-12) create complex, intricate forms. Most designs work best with 5-7 points.
3. Control Randomness: The randomness slider determines how wild or smooth your blob is. Low randomness (0-30%) creates gentle, flowing curves. High randomness (70-100%) creates dramatic, abstract shapes. Medium randomness (40-60%) offers a balanced, organic look.
4. Set Your Size: Adjust the blob size to match your design needs. The size only affects the preview - SVG files scale perfectly to any dimension without quality loss.

Customizing Colors

Solid Colors: Choose "Solid Color" from the fill type dropdown and select your color using the color picker. Click the preset color buttons for quick access to popular design colors.

Linear Gradients: Select "Linear Gradient" to blend two colors in a straight line. Choose your two colors and adjust the gradient angle (0° is horizontal, 90° is vertical, 45° is diagonal). Gradients add depth and visual interest to your blobs.

Radial Gradients: Choose "Radial Gradient" for colors that radiate from the center outward. This creates a spotlight or glow effect, perfect for eye-catching hero sections.

Using Quick Presets

Not sure where to start? Try our presets: Simple (3-4 points, low randomness) for clean, minimal designs; Organic (6 points, medium randomness) for natural, flowing shapes; Complex (10 points, medium randomness) for intricate, detailed forms; Smooth (6 points, low randomness) for gentle curves; or Wild (8 points, high randomness) for dramatic, abstract shapes.

Downloading and Using Your Blob

Download SVG: Click "Download SVG" to save the blob as an SVG file. Use this in design software (Figma, Sketch, Illustrator) or directly in your website code. SVG files are tiny (usually under 1KB) and scale perfectly.

Copy SVG Code: Click "Copy SVG Code" to copy the raw SVG markup. Paste this directly into your HTML for inline SVG, or save it as a .svg file. Inline SVG allows you to animate and style the blob with CSS.

Implementation Examples: Check the usage examples tabs for ready-to-use code snippets. We provide examples for HTML (inline SVG), CSS (background image), and React (component). Simply copy and paste into your project.

Best Practices

For website backgrounds, use larger blobs (600-800px) with subtle colors that don't overpower content. For decorative elements, smaller blobs (200-400px) work well. Layer multiple blobs with different colors and opacities for depth. Use gradients to add dimension. Keep complexity moderate (5-7 points) for most designs - too many points can look chaotic. Test your blobs on both light and dark backgrounds to ensure they work in your design.

Common Use Cases

Hero Section Backgrounds: Large, colorful blobs behind hero text create modern, engaging headers. Use 2-3 overlapping blobs with gradients for depth.

Section Dividers: Place blobs between content sections to add visual interest and break up long pages. Use colors that match your brand palette.

Decorative Elements: Small blobs as decorative accents near buttons, images, or important content draw attention without being distracting.

Loading Animations: Animate blob shapes with CSS or JavaScript for unique loading indicators or background effects.

Social Media Graphics: Use blobs as backgrounds for social media posts, profile pictures, or story templates. They add a modern, professional touch.

Advanced Tips

Combine multiple blobs with different opacities for layered effects. Animate blobs using CSS animations or JavaScript libraries like GSAP. Use CSS filters (blur, brightness) for additional effects. Export multiple variations and switch between them for dynamic backgrounds. Adjust blob colors to match your brand using the color pickers.
