NSS BG

Getting Started

Getting started

Everything you need to remove your first background in under two minutes.

What you need

NSS Background Remover runs entirely in your browser. You don't need to create an account, install software, or pay for anything. All you need is a modern web browser and an image.

Recommended browsers: Chrome 94+, Edge 94+, Opera 80+, Firefox 90+, Safari 16.4+

Step 1 — Upload your image

Drop your image onto the upload zone on the home page, or click anywhere in the zone to open a file picker. You can also paste an image directly from your clipboard with Ctrl+V (or Cmd+V on Mac).

Supported formats: PNG, JPG/JPEG, WebP, AVIF, HEIC (iPhone photos).

Step 2 — Wait for the AI

After uploading, the AI model automatically removes the background. The first time you use the tool, it needs to download the model weights (~80 MB for Fast, ~180 MB for Best Quality). This takes a moment on slower connections but the weights are then cached, so future uses are instant.

A progress bar shows inference status. Most images finish in under five seconds on a modern computer.

Step 3 — Review the result

Once processing is complete, you'll see a preview with a checkerboard pattern behind the removed areas. That checkerboard means the background is truly transparent — not white, not black, genuinely empty.

Click the image to open it in the editor where you can:

  • Erase or restore areas with the brush tool
  • Refine edges with feathering and smoothing
  • Add a new background colour, gradient, or image
  • Export in PNG, WebP, AVIF, or JPG

Step 4 — Export

Click Export in the top right of the editor. Choose your format (PNG is usually best for transparency), and the file downloads instantly. No watermark, no upload to our servers — the file comes straight from your browser.

Tips for best results

  • For hair, fur, and fine details: select Best Quality (RMBG-2.0) before processing
  • If edges look rough: open the editor and use Edge Refinement → Feather
  • If colours look wrong near edges: turn on Decontaminate in Edge Refinement
  • For batch work: upload multiple images at once — they queue and process sequentially
