100KB Extension v1.1.1: Compress & resize files in 0ms directly in Google Chrome
Remove background from images and passport photos online for free in full original quality. Unlike other expensive alternatives, we do not reduce quality.
Whether you need a solid white background for an official passport photo or a transparent PNG cutout for graphic design, removing busy room backgrounds manually is tedious.
100kb.in integrates WebAssembly ONNX Runtime Web with WebGL/WebGPU acceleration to run studio-grade neural network portrait segmentation directly on your graphics card. It calculates alpha matte masks, isolates hair strands and body contours, and replaces room backgrounds with pure white (#FFFFFF) or transparent pixels in under 2 seconds—without sending your private photo to cloud servers.
| Processing Mode | Neural Model / Engine | Alpha Channel Depth | Output Format | Precision Ceiling |
|---|---|---|---|---|
| Portrait Cutout | ONNX Runtime Web (U-Net AI) | 8-bit Smooth Alpha Matte | PNG (Transparent) | Studio Hair & Edge Cutouts (<15ms) |
| White Background Composite | Solid Color Canvas Rasterizer | 24-bit RGB (White #FFFFFF) | JPG / PNG | 100% (Passport, Visa & ID Portals) |
| E-commerce Product Isolation | Edge Contrast & Boundary Detection | 8-bit Anti-Aliased Mask | PNG | Shopify, Amazon & Etsy Product Photos |
