FAQ
Is my image uploaded anywhere?
No. The enlargement happens entirely in your browser on a canvas. Your image never leaves your device, so it works offline and stays private.
Is this AI upscaling?
No — this is high-quality classic enlargement: smooth resampling plus optional sharpening. It makes images larger and cleaner than a plain stretch, but it can’t invent detail that isn’t there the way a trained AI model can. (An offline AI option may be added later.)
When does it work best?
On logos, graphics and modest enlargements. Very low-resolution photos will still look soft when blown up a long way — sharpening helps the edges, but it can’t recover lost detail.
