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.
Why Lumisphere
Design assets you own, made in your browser.
Every visual here is generated from pure maths — SVG paths and Canvas pixels computed live, never a stock image dressed up. That has real consequences: the output stays razor-sharp at any size, the files are tiny and weightless to ship, and you can recolour or reshape a result without ever losing fidelity. Nothing you make is uploaded to a server — no sign-up, no logo burned into your exports, and no daily cap counting down in the corner. Where other tools gate the good export behind a sign-up or smear a logo over the preview, Lumisphere simply hands you the finished file. What you copy or download is plain, framework-neutral PNG, SVG or CSS — paste it into React, a static site, a Figma frame or a slide deck and it just works. The assets are yours to use, freely and without strings.
It’s built for the people who actually ship visuals: designers reaching for a backdrop, developers who’d rather not hand-write a gradient, and creators putting together a thumbnail before lunch. The rhythm is the same across every generator — explore, refine, export. Randomise until something genuinely sings, nudge the controls until it’s exactly right, then export in a single click. Start with the mesh gradient generator or layer up a few SVG waves and you’ll see the loop in seconds. The same care extends to the private image utilities: the image converter, the background remover and the favicon maker all run entirely on your device, so the files you drop in never leave the browser. No upload, no queue, no copy sitting on someone else’s disk — just the result, made locally and gone the moment you close the tab.
