Frequently asked
What is Lumisphere?
Lumisphere is a free studio of generative visual tools for designers & creators. Make mesh gradients, glassmorphism, SVG waves, blobs, noise textures and seamless patterns, then export them as PNG, SVG or CSS — all in your browser.
Is it really free?
Yes — every generator and image tool is free, with no sign-up, no watermark and no usage limits. You own whatever you export and can use it in personal and commercial projects.
What can I export — PNG, SVG or CSS?
Most tools export all three: a transparent PNG for slides & social, an SVG for crisp vector use, and a CSS snippet (or data-URI background) to paste straight into a site. Pick whichever your project needs.
Are my files private?
Completely. The image converter and background remover run entirely in your browser — nothing is uploaded, nothing is stored on a server, and they work offline once the page has loaded.
