What is SVG Blob Generator?

A tool for generating organic, naturally curved blob-shaped SVGs. Add softness to modern designs as background decorations or logo bases for websites.

Simply select a color with the color picker and adjust smoothness and edge count with sliders to create unique shapes. Change parameters while viewing the real-time preview, and try various variations with the shuffle function to find shapes that match your design vision. Generated SVG code can be copied or downloaded with one click and used immediately in websites or design projects.

Use Cases

Blob shapes add organic impressions to linear designs, creating visual approachability.

• Hero section backgrounds: Eye-catching decoration for landing pages and homepages
• Service introduction cards: Add accents to product or service description sections
• Logo design base: Incorporate distinctive shapes into company or brand logos
• Social media backgrounds: Add visual elements to Instagram or Twitter post images
• App UI decoration: Use as backgrounds or illustrations in mobile and web apps

Also useful for blog featured images and presentation materials, achieving simple yet memorable designs.

Basic Usage

1. Select color: Set the blob fill color with the color picker
2. Adjust shape: Change appearance with smoothness and edge count sliders
3. Shuffle: Generate random shapes to explore ideal designs
4. Copy or Download: Get the SVG code for shapes you like

Generated SVG code can be directly embedded in HTML or used as a CSS background-image.

<!-- Embed directly in HTML -->
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
  <path fill="#f05672" d="M 50, 100 C 50, 80..." />
</svg>

For CSS backgrounds, Base64 encoding the SVG code or loading it as an external file is convenient.

Parameter Details

Smoothness

A parameter that adjusts the roundness and randomness of blob shapes. Larger values create smooth curves close to perfect circles, while smaller values create irregular, organic shapes.

• 8-10: Soft and gentle impression. Suitable for corporate sites and service introductions
• 4-7: Moderate randomness, versatile. Easy to use in many design scenes
• 0-3: Impactful irregular shapes. For art sites and creative expressions

Edge Count

Sets the number of vertices that make up the blob. More edges create complex, smooth curves, while fewer edges create simple, geometric shapes.

• 3-5: Simple shapes close to triangles or polygons. For icon or logo bases
• 6-10: Well-balanced organic shapes. Recommended for background decorations and card elements
• 11-20: Fine, complex curves. Suitable for large background areas and artistic expressions

Why Choose SVG Blobs

High Quality at Any Size

Vector format means no quality degradation when scaling. Ideal for responsive design, displaying beautifully at any resolution from smartphones to 4K displays.

Lightweight and Fast Loading

Overwhelmingly lighter than PNG or JPEG images. Typical blob SVGs are only a few KB, so they don't affect page load speed and maintain performance even when using multiple blobs.

Flexible Customization

Edit SVG code in text editors even after generation, making color changes and gradient additions easy. Combine with CSS animations or JavaScript to achieve interactive expressions like shapes that change on mouse hover.

Browser Support and Compatibility

SVG is supported by all major browsers and requires no additional plugins or libraries. Embedding directly in HTML eliminates external file loading, allowing simple implementation.
