Good to know
How do I make a background transparent?
Drop your image in, let Lumisphere detect the background colour (or pick it with Pick from image), tune the edge if needed, and download a transparent PNG. For a person, use the AI mode.
Will it stay transparent when I download it?
Yes — the file is saved as a PNG, which supports transparency. Open it in Canva, Figma, PowerPoint or any editor and the background stays see-through.
Is there a watermark or sign-up?
No. It’s completely free, needs no account and adds no watermark — and you keep the full-size result (up to 2000 px), not a shrunken preview. Your image is processed on your device and never uploaded.
What kinds of images work best?
Logos, icons, product shots and graphics on a solid or near-solid background come out cleanest. For a person or portrait, the on-device AI mode is hair-aware.
