What is a blob background generator?
A blob background generator builds abstract organic compositions out of overlapping rounded shapes ("blobs"). MagicPattern's blob composition tool lets you tweak each blob's color, gradient, outline and position independently, refresh for unlimited variations, and export the result as SVG, PNG or JPG for hero sections, social posts and product branding.

Hi fellow creator!
I'm Jim, the founder, designer & engineer behind the MagicPattern toolbox.
For many years, I was struggling to create engaging visuals for products, branding and interfaces. Their creation required pro design skills or many hours of practice.
That's why I build MagicPattern. My mission is to help people create pro graphics with no effort and no prior design knowledge.
