Frequently Asked Questions
Yes, completely free. There are no subscriptions, no daily limits, no watermarks, and no account sign-ups required. You can remove backgrounds from as many photos as you need.
No. Unlike most background removal tools, SizeHex runs the AI model directly in your browser using WebAssembly (Wasm) and ONNX Runtime. Your images never leave your device — they are processed entirely on your local CPU/GPU. This means 100% privacy and zero risk of your photos being stored or accessed by third parties.
Our background remover accepts JPG, JPEG, PNG, and WebP images as input. The output is always a transparent PNG file — the standard format for images with transparent backgrounds, compatible with virtually all design software, social media platforms, and web apps.
Yes! Our AI model is specifically trained to handle complex edges including curly hair, straight hair, fluffy fur, and fine details. It performs significantly better than basic tools that only handle simple solid-background cutouts. After AI processing, SizeHex applies additional edge refinement to eliminate common color fringing artifacts for the cleanest possible result.
Because the AI model runs locally in your browser, the processing speed depends on your device's CPU and available RAM. On first use, the model also needs to be downloaded (around 10–20MB) and cached in your browser. Subsequent uses will be much faster. For best performance, close other heavy browser tabs and use a modern browser like Chrome or Edge on a desktop or laptop.
AI-based background removal works best on images with a clear subject and a reasonably distinct background. If the result isn't perfect, try using a photo with better lighting, higher contrast between subject and background, or a simpler background color. For complex composites, we recommend downloading the PNG and doing minor cleanup in a free tool like GIMP or Canva's background eraser.
