SVG Blob Generator Online

                    
Updated 2026-07-09

                            
Generate organic SVG blob shapes online for free. Drag the complexity and randomness sliders, pick a
colour, and randomize until you find a shape you like — then copy or download the SVG. Everything runs
in your browser, so nothing you create is uploaded.


Those soft, irregular blob shapes are everywhere in modern web design, but drawing a smooth organic
outline by hand is fiddly. This generator places points around a circle at random distances and joins
them with a smooth spline, so every click gives you a clean, scalable blob — ready to drop in as a
background shape, an image mask, or a decorative accent.

No. The blob is generated entirely in your browser, so nothing you create leaves your machine.

                                

                                                            

                                    
                                    
Points are placed around a circle at slightly random distances, then joined with a smooth Catmull-Rom spline so the outline flows naturally. More points and more randomness give a more irregular shape.

                                

                                                            

                                    
                                    
Complexity sets how many points form the outline, so higher values allow more lobes. Randomness sets how far each point strays from a perfect circle, so higher values make the blob more organic and uneven.

                                

                                                            

                                    
                                    
Yes. The SVG uses a single fill attribute you can change in code or a design tool, and because it is vector it scales to any size without losing quality.

                                

                                                            

                                    
                                    
Paste it inline in HTML, use it as a background shape, an avatar mask, or a decorative section divider, or import it into design tools that accept SVG.
