Does the Image Upscaler upload my photo to a server?

No. The upscaling pipeline is browser-first and runs locally on your device. Your image is not uploaded for processing.

What is the difference between 2x Safe Mode and 4x WebGPU?

2x Safe Mode is the broad-compatibility path that works on more devices. 4x WebGPU is the premium local path for browsers and hardware that support WebGPU acceleration.

What types of images work best with the Image Upscaler?

It is tuned for real photos such as portraits, product shots, travel images, and compressed camera photos. Logos, vectors, transparent design assets, and animated images are outside the v1 target.

Will the upscaled image look exactly like a native high-resolution original?

No. AI upscaling can recover clarity and detail, but it cannot recreate the full fidelity of an image that was originally captured at a much higher resolution.

Why is 4x disabled for some images?

Very large 4x jobs can exceed safe browser limits. When that happens, the tool keeps 2x available and asks you to switch to Safe Mode or crop first.
