Frequently Asked Questions
What is a blob shape?
A blob is an organic, rounded shape with irregular but smooth edges. Blobs are popular in modern UI design for adding visual interest and a friendly, approachable feel to layouts. They are commonly used as background decorations, image masks, and illustration elements.
Can I control the complexity of the blob shape?
Yes, the generator provides a complexity slider that controls how many points define the blob's outline. Lower values create simpler, smoother blobs while higher values produce more irregular, complex organic shapes.
How do I use blob shapes as image masks?
Export the blob as SVG and use it as a CSS clip-path or SVG clipPath element to mask images into organic shapes. This technique is widely used in portfolio sites, about pages, and team member photos.
