Frequently Asked Questions
Is this generative AI upscaling?
No. It uses high-quality browser resampling plus sharpening. It cannot invent missing detail like a dedicated AI super-resolution model.
Will quality look perfect at 4×?
Larger scales look softer. Start with 2× when possible, or enhance brightness/contrast afterward.
Are images uploaded?
No. Upscaling runs in your browser.
