THE PROCESS

HOW IT
WORKS.

01

SELECT YOUR IMAGE

Drag and drop or click to browse. Backgrone supports JPEG, PNG, WebP, and HEIC formats. Your image is read directly into browser memory using the File API — it never touches a server.

AI PROCESSES LOCALLY

Our neural network runs entirely in your browser via WebAssembly (WASM). Choose from three AI engines — Precision (ISNet fp16), Lightweight (ISNet uint8), or Balanced (RMBG-1.4) — each optimized for different quality and speed requirements.

BROWSER COMPATIBILITY

Backgrone requires a modern browser with WebAssembly and SIMD support. Chrome 91+, Firefox 89+, Safari 16.4+, and Edge 91+ are fully supported. WebGPU acceleration is available in Chrome 113+ for even faster processing.
