About Add White Background to Image

Useful details for choosing formats, browser settings, and privacy-safe local processing.

What Add White Background to Image does

Add White Background to Image separates the subject from its photo and rebuilds the scene on a flat background color, which is the usual requirement for marketplace and catalog listings.

The separation model runs in your browser through WebAssembly. The image itself is never uploaded — only the model file is downloaded, once, and then cached.

  • Best for: Amazon and Etsy listings, Shopify product photos, Catalog sheets, Marketplace compliance
  • Input: JPG, PNG, WebP, and browser-supported images
  • Output: JPG, PNG, or WebP on a solid background

Settings and output control

Choose the background treatment — transparent, white, or a custom color — and the export format for the queue.

The edge control tightens the alpha matte when a cutout looks soft. Smooth gradients are kept for hair and fur; a firmer setting cleans up hard-edged products.

  • Files stay on this device by default
  • Batch export is available after processing
  • Model runs on this device after a one-time download

Browser support and practical limits

Background removal uses a small ONNX segmentation model executed by onnxruntime-web with WebAssembly, so the browser does the work instead of a server.

The first run downloads the model and the inference runtime once. After that they are cached, and processing stays on this device. Desktop browsers handle batches best because mobile browsers have less memory.

  • Desktop batch: up to 50 images
  • Max image size: 8192 x 4096 px each
  • Mobile: smaller batches recommended

FAQ

Common questions

Is the white background really pure white?

Yes. The subject is cut out first, then composited onto the exact color you pick — #ffffff by default — so the background is a flat, uniform white rather than a brightened photo.

Which marketplaces accept this output?

Pure white backgrounds are the common requirement for Amazon, Etsy, and most catalog feeds. Export as JPG for listings, or keep PNG if you need transparency.

Are my product photos uploaded?

No. Everything runs in your browser. Only the segmentation model is downloaded, and it is cached after the first use.

Can I use another background color?

Yes. Switch the background control to Custom and pick any color — useful for brand-colored backdrops or pastel listing styles.

How many photos can I process?

Up to 50 images per batch on desktop. Mobile browsers have less memory, so smaller batches are recommended on phones.
