Background Remover

Clean cut-outs, careful edges

Choose a fast local model or a detail-first pass, then refine the mask and export real transparency.

Difficult cases

Compare the edge before you process

Cycle through hair, fur, glass, plastic, shadows, jewellery, fabric, people, and products. Each bundled fixture opens with known local settings.

Built for serious work

Real-tool features without server costs or subscriptions.

Layers

Drop multiple files, reorder, blend modes, opacity, lock, rename. Layer keyboard shortcuts (Ctrl+J, Ctrl+Shift+]/[).

3D preview + relief

Orbit the canvas as a flat 3D plane, or generate a depth-displaced bas-relief mesh. Record 360° orbit as WebM.

Edge refinement

Feather, smooth, and decontaminate cut-out edges; brush erase / restore and magic-wand for pixel-perfect masks on hair, fur, and glass — then run a BiRefNet best-quality pass.

One-time use by design

Nothing persists after you close the tab — no accounts, no stored projects, no session history. Open the tool, do the work, download the result, done.

Studio environments

Switch the editor between Photo, Real Estate, and Lifestyle modes — furniture staging and scene backgrounds run on the same layer engine as the cut-out tools.

Video object remover

Click an object in a clip — AI outlines it. Remove, blur, or pixelate it across frames with tracking, plus one-click license-plate blur. Edits persist on the timeline and each can be undone.

Offline PWA

Install once, work offline. Service worker pre-warms AI models so first-run is fast and subsequent runs are instant.

Browser-local media

WebAssembly + WebGPU media processing runs on your device. Files are never uploaded; optional analytics and advertising are controlled separately.

Why NSS is different

A connected set of private browser tools: inspect real outputs, manage downloaded models, continue into an editor, and keep control of every file.

100% Private

Everything runs on your device using in-browser AI. Nothing is transmitted to any server — not the file, not metadata, not filenames.

True Alpha Channel

We export straight (non-premultiplied) alpha so transparent PNGs open with a real checkerboard in Photoshop and Figma — no black halos.

Free Forever

No paywall, no watermark, no premium tier. The full-quality AI is free, supported by non-intrusive ads.

Works Offline

Once loaded, the app and AI models cache locally. Process files without an internet connection. Installable as a desktop or mobile app.

On-device by design

Your media stays where it belongs

Images and videos are decoded and processed locally. Background removal downloads its selected model once, stores it in browser cache, and exposes that storage through Downloads & storage so you can inspect or delete it at any time.

Local input

Media is opened from your device; it is not uploaded for processing.

Visible storage

Downloaded model size and cache state are manageable from one place.

Local handoff

Processed video results open in the editor without another upload.

How it works

One local workflow, four simple stages

  1. 01

    Choose a focused tool

    Start from the remover, an editor, an enhancer, or a compact utility.

  2. 02

    Process on your device

    Canvas, WebAssembly, WebGPU, and browser codecs do the work locally.

  3. 03

    Inspect the real result

    Preview the actual output, its format, dimensions, and processing diagnostics.

  4. 04

    Continue or export

    Download immediately or carry the processed blob into the matching editor.
