Background Remover

About the Background Remover

Background Remover separates the main subject of a photo from its background and gives you a PNG with a transparent background. It uses U²-Net-p, a compact open-source salient-object segmentation model, running through ONNX Runtime Web inside a background worker in your own browser tab.

The engine files (about 15 MB) are only downloaded from this site the first time you click “Remove background”; after that your browser can reuse them. Your image is never uploaded. Results depend on the picture: a clear subject on a contrasting background usually works well, while fine hair or fur, glass and other transparent objects, backgrounds similar in colour to the subject, and busy scenes can need manual touch-up in an image editor.

How to use

1. Click the upload area or drag in a JPG, PNG or WebP image (up to 25 MB and 16 megapixels).
2. Click Remove background. The first run loads the engine and shows its progress; later runs start straight away.
3. Compare the Original and Result previews, then drag the before/after slider to inspect the edges.
4. Click Download PNG to save the cut-out with its transparent background.
5. Use Reset to clear the image and result and start again.

Key features

• Real on-device segmentation with the U²-Net-p model — not a simple colour-key or a fake checkerboard preview.
• Runs in a Web Worker, so the page stays responsive while the model works.
• The engine loads only when you ask for it, from this site — no CDN or third-party service.
• Side-by-side previews plus a before/after comparison slider.
• Full-resolution PNG output with an 8-bit soft-edged alpha channel.
• Clear messages for unsupported, damaged and oversized files.

Best practices

• Use a photo where the subject is in focus and clearly separated from the background.
• Good, even lighting and a contrasting background give cleaner edges.
• Check hair, fur, fingers and thin objects with the comparison slider before using the result.
• For product shots, crop close to the product first with the Image Cropper & Rotator.
• Keep the PNG for transparency; convert to JPG only after placing the cut-out on a new background.

Benefits

• Private: the image stays on your device from start to finish.
• No watermark, account or credit system.
• No usage limits — process as many images as you like.
• Quick cut-outs for listings, slides, thumbnails and profile pictures.
