Frequently asked questions
Will the same seed always give the same blob?
Yes — the generator uses a seeded random function, so a given seed, point count and size always reproduce the same shape.
Can I animate the blob?
The generated SVG is a static path; add your own CSS or SMIL animation to morph or rotate it.
Is this tool free to use?
Yes, completely free on FreeToolsNets, with no sign-up and no limits.
Is my data sent to a server?
No. Everything runs locally in your browser using JavaScript — nothing you enter is uploaded anywhere.
