Can I use this tool to make white background passport photos?

Yes! Select the Solid White background option to meet US Visa, Schengen, and India Passport requirements instantly.

Does background removal send my private photos to cloud servers?

No. The neural network model executes entirely inside your browser memory using WebAssembly and WebGPU.

What image formats work best for AI background removal?

JPG, PNG, and WEBP portraits with clear lighting contrast between subject and background yield best results.

Can I smooth hair strands or fine edges on cutouts?

Yes! Our WebGL shader applies anti-aliased edge smoothing for realistic hair strand isolation.

HMPO UK Visa Image Requirements & Resizer

British immigration authorities rely on automated biometric scans, making it critical that your UK visa photo possesses a plain cream or light grey backdrop rather than pure white. Our system meticulously calibrates your upload to the exact 45x35 millimeter standard, saving you from frustrating delays at the Home Office. 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.
