How AI Blur & Background Bokeh Tool Works in Your Browser

Unlike conventional online conversion websites that upload your files to remote cloud servers, Lumino processes your media 100% client-side inside your browser sandbox using modern WebAssembly (WASM), WebGPU, and the HTML5 Canvas 2D API.

This means your sensitive photos, identity cards, passport scans, and proprietary design files are processed directly on your local device hardware (RAM/GPU) and are never transmitted across the internet.
