Does BG-Zero upload my images to a server?

Accepted Answer

No. All AI processing runs locally in your browser using WebAssembly technology. Your images never leave your device, ensuring complete privacy and data security.

Question 3

Which AI engines does BG-Zero support?

Accepted Answer

BG-Zero offers three AI engines: imgly (IS-Net model, ~40MB, compatible with all browsers), Transformers.js (RMBG-1.4, ~176MB, best quality, requires WebGPU), and rembg-web (7+ models from 4.7MB, MIT licensed).

Question 4

Can I use BG-Zero offline?

Accepted Answer

After the first visit, AI model files are cached in your browser. Subsequent visits can process images even without an internet connection, as long as the model cache hasn't been cleared.

Question 5

What image formats are supported?

Accepted Answer

BG-Zero supports JPG, PNG, WebP, and BMP formats. The maximum file size is 25MB. Results are exported as transparent PNG files.

Question 6

What's the difference between Auto and Manual mode?

Accepted Answer

Auto mode uses AI to detect and remove backgrounds with one click — perfect for most images. Manual mode lets you pick specific colors with an eyedropper and use Flood Fill for precise removal, with a mask brush to protect areas you want to keep.
