FAQ
How does background removal work?
We use an AI segmentation model (ONNX) that runs entirely in your browser. It identifies the foreground subject and removes the background, producing a transparent PNG. No data is sent to any server.
Can I remove backgrounds from multiple images at once?
Yes! Select multiple files at once or add more after the first. Each image is processed sequentially through the AI model, and you can download results individually or all at once.
Is there a file size limit?
There's no hard limit since processing happens in your browser. Images up to 4000x4000 pixels work well on most devices. Very large images may take longer.
What output format do I get?
The result is always a PNG with a transparent background, which you can use in design tools, presentations, or on the web.
Why does the first image take longer?
The AI model (~40MB) needs to download once on first use. After that, it's cached in your browser and subsequent removals are much faster (typically 2-10 seconds).
Is my image data private?
Yes. Everything runs locally in your browser using WebAssembly and ONNX Runtime. Your images are never uploaded to any server. We cannot see or access your images.
Can I choose a background color after removing the background?
Yes. After removal, you can switch between transparent (checkerboard preview), white, black, red, blue, or any custom color using the color picker. The result updates instantly without re-running the AI model.
What download formats are available?
You can download as PNG (supports transparency, recommended for most uses), JPEG (smaller file size, white background applied automatically if you chose transparent), or WebP. PNG is selected by default.
How accurate is the background removal?
The tool uses the RMBG-1.4 model, which works well for clear foreground subjects — portraits, products, animals. After processing, an edge quality indicator (1-5 scale) shows how sharp the cutout edges are. For complex cases like wispy hair against busy backgrounds, results may be imperfect.
Does it work on mobile phones?
Yes, but performance varies. The AI model requires ~40MB of memory. Modern iPhones and Android flagships handle it well. Older or low-RAM devices may be slow or fail on large images. Reduce image size with our <a href="/ai/image/resize">Image Resizer</a> before processing if you hit issues.
How does this compare to remove.bg or Canva?
remove.bg and Canva upload your images to their servers and limit free usage. Our tool runs the AI model entirely in your browser — no upload, no privacy concerns, and unlimited free use after the initial model download.
Can I remove backgrounds and then add a watermark?
Yes. Remove the background first, download as PNG (to keep transparency), then open the result in our <a href="/ai/image/watermark">Watermark tool</a> to add text or logo overlays.
What image formats can I upload?
JPEG, PNG, and WebP. The output is always PNG with transparency by default. You can also download as JPEG (transparent areas become white) or WebP from the format selector.
Can I replace the background with a custom image?
Not directly in this tool. Remove the background here, download the transparent PNG, then use a design tool like Figma or Canva to place it on a new background. You can also use our <a href="/ai/image/watermark">Watermark tool</a> for simple overlays.
