No. The photo itself never leaves your device, processing happens entirely in your browser via WebAssembly. What does come from a server is the ML model (~170 MB), fetched once from staticimgly.com. After that it's in your browser cache.

On a fast home connection: 15-25 seconds the first time. On mobile 4G: 2-3 minutes. After that, zero: your browser caches the model and loads it instantly on subsequent uses. We deliberately use the largest model (isnet full-precision), the smaller variants produce visibly weaker edges.

The model is strong on people, products, and pets. A portrait, a product shot on a plain background, or your dog in the garden, it's stable there. Architecture (white siding + white sky), glass, thin objects like hair or branches against a busy backdrop, or photos with similar luminance on both sides of the edge are harder. The model 'guesses' and you get semi-transparent patches or missed edges. A different photo with more colour contrast between subject and background often works much better. For critical cut-out work (product photos for your store) a professional tool is still worth it.

JPG, PNG, WebP. HEIC (iPhone photos) get auto-converted to JPG before processing. Output is always PNG, with transparency or a solid background colour of your choice.

Yes. We use @imgly/background-removal, an open-source library with a self-trained model. No API calls, no credits, no rate limits. For commercial use, check the library license.
