How does in-browser AI image upscaling and restoration work?
Drop & Clean runs Real-ESRGAN Compact in your browser using WebGPU and WebAssembly. Images are processed locally and are not uploaded; anonymous diagnostics may be sent if enabled.
Will upscaling 4K images cause memory crashes or out-of-memory errors?
No. Our dynamic Tiling coordinator partitions high-resolution images into 256x256 patches with cosine blending, preventing WebGPU out-of-memory errors on any hardware.
Are my private photos and graphics secure?
Image restoration runs locally in your browser and images are not uploaded. Anonymous diagnostics may be sent according to your privacy settings; they do not include image contents.
