About ZeroBG

Version 1.0 — 2026

What it does

ZeroBG removes the background from any image in seconds. Upload a photo — a portrait, a product shot, a character reference — and the AI isolates the subject and returns a clean PNG with a transparent background, ready to use anywhere.

How it works

ZeroBG runs entirely inside your browser using RMBG-2.0, a state-of-the-art image segmentation model by BRIA AI, loaded and run via the Hugging Face Transformers.js library. When you first visit, your browser downloads the model directly from Hugging Face's CDN — around 170 MB, cached locally after that. Every subsequent use is instant. Processing happens on your device via WebGPU or WebAssembly.

No images are sent to any server. No account required. No watermarks. No limits.

Why in-browser AI?

Running AI on the client means your data stays with you. There is no backend that stores, logs, or processes your images. It also means the tool is free to use with no usage limits — the compute is yours, not ours.

Best results

• Clear subject against a distinct background
• Good lighting, minimal motion blur
• Portrait, product, and character shots work best
• Supported formats: JPG, PNG, WEBP up to 20 MB
