Technical limits and privacy
Engine: U2NetP 320, ONNX Runtime Web 1.27.0 WASM. WebGPU is disabled in this release because of the strict dynamic-code security rule.
JPG cannot preserve transparency. AVIF decode and encode support varies by browser. Above 12 MP, optional low-memory mode reduces the working and output copy; the default mode preserves full resolution.
