Uses a compact super-resolution neural network (ESRGAN-slim) that runs entirely in your browser to intelligently reconstruct detail when scaling an image up to 2x, 3x, or 4x its original size.

よくある質問 (FAQ)

How is this different from just resizing an image?
A regular resize stretches existing pixels and looks blurry. This uses an AI super-resolution model to reconstruct plausible detail, producing a sharper result.
Does this run on Anthropic or DCPIXEL servers?
No — the AI model downloads once to your browser (and is cached for next time) and all processing happens on your own device.
Is there a size limit?
Source images are capped at 10MB. Very large images take longer to process since everything runs on your device's hardware.
