How the Browser-Side AI Works
Unlike remove.bg or Canva, this tool runs a real neural network inside your browser using WebAssembly and WebGL. The AI model (RMBG-1.4) is downloaded once (~40MB) and cached for instant reuse.
This means your photos never leave your device. There's no server, no API call, no upload. The processing happens on your GPU (or CPU), making it faster than most cloud services for high-resolution photos.
E-commerce Background Tips
- Amazon: Requires pure white (#FFFFFF) background, product filling 85% of frame
- Shopify: White or light gray works best; enable "Soft Shadow" for depth
- eBay: White or light solid color; no logos or text allowed
- Etsy: More creative freedom; try custom brand colors
- Headshots: Use transparent PNG and compose on any background in Canva
- Logos: Export as transparent PNG for use on any website
Frequently Asked Questions
Is this really free with no limits?
Yes! The AI runs in your browser using your device's processing power. We don't need servers, so we don't charge. No resolution limits, no watermarks.
How does the manual brush work?
Switch to Erase mode to remove areas the AI missed, or Restore mode to bring back areas that were incorrectly removed. Adjust brush size with the slider.
Can I add a white background for Amazon?
Yes! Click the white background button to add a pure #FFFFFF background, which meets Amazon product photo requirements.
