Frequently Asked Questions
Everything you need to know about the background replacer.
- Is the background replacer really free?
- Yes, completely free with no signup required. The AI model runs entirely in your browser — we never see your photos and there's no premium plan.
- Are my images uploaded to a server?
- No. All processing happens locally in your browser using WebAssembly and the Canvas API. Your images never leave your device.
- What image formats are supported?
- Both subject and background images accept PNG, JPEG, and WebP. The output is always a high-quality PNG.
- What is the maximum image size?
- Up to 20 MB per image. For best results keep images under 4000×4000 px. Larger images may take longer to process.
- How does the AI remove the background from the subject?
- GenieTools uses an on-device WebAssembly AI model (the same one powering the Background Remover) to detect and cut out the subject with pixel-level precision.
- Can I use any image as the new background?
- Yes. Upload any PNG, JPG, or WebP as the background. The tool automatically scales and centres it to fit the subject image dimensions.
- Can I use the result for commercial purposes?
- Yes. The processed image is entirely yours. Just ensure you hold the rights to both the subject photo and the background image.
- Why is the first replacement slower?
- The first run downloads the AI model (~30 MB) to your browser. Subsequent replacements are much faster because the model is cached.
