What you get
Progressive resampling
The image is enlarged in repeated small steps with smooth interpolation, which preserves far more edge detail than a single hard stretch.
Edge-aware sharpening
An unsharp-mask pass restores the micro-contrast that any enlargement softens, with strength you control.
Honest about what it does
This is high-quality resampling, not generative AI invention. It will not hallucinate detail that was never captured — which is exactly what you want for client work.
