Frequently asked questions
Is this AI upscaling?
No — it uses high-quality mathematical resampling, which keeps edges smooth and natural but can't invent detail that isn't in the original.
What's the largest output?
Up to about 40 megapixels (for example 4× a 1600×1000 image).
Is my image uploaded?
