Our mission
About NSS Background Remover
A free, privacy-first tool that does one job exceptionally well.
What we built and why
NSS Background Remover exists because the free tools already out there cut a corner that most users don’t notice until it’s too late: they export premultiplied alpha. Your transparent PNG looks fine in a browser but shows a black background the moment you open it in Photoshop, Figma, or any professional design tool. We built a tool that gets this right by default — every export uses straight alpha, validated automatically before the download starts.
The other commitment is privacy. Every other free tool either uploads your images to a server or charges you for “offline” mode. We built ours so that the AI runs entirely in your browser using WebAssembly and WebGPU. Your images are never transmitted anywhere — not to us, not to anyone. This isn’t a policy promise; it’s an architectural one. There is no server that could receive your image even if we wanted to.
It’s free because we believe quality tools shouldn’t require a subscription. NSS Background Remover is ad-supported — non-intrusive display ads help keep the lights on without compromising the experience or your privacy.
Our principles
- Privacy is structural, not a policy
- The app is designed so that transmitting your images is technically impossible. No promises to trust — just architecture.
- Quality is the brand
- True alpha, soft edges, no color spill. If an export would embarrass a professional, it does not ship. The Cardinal Test: cut out a Yorkshire Terrier with our best quality model and open it in Photoshop. Natural fur, no halo, no black edges.
- Free means free
- No watermarks, no usage limits, no "premium" quality tier. The same AI model runs for your first image and your thousandth.
- Cutout-first, but a full suite around it
- Background removal is the centre of gravity, but every adjacent tool — image and video editors, image and video upscaling, and 30+ utilities — runs by the same client-side, no-account, no-upload rules.
