How does image upscaling work?

The image is drawn onto a Canvas at a higher resolution using drawImage with scaled dimensions. This is a simple upscale — for AI-powered super-resolution, more advanced tools are needed.

Will upscaling improve quality?

Simple upscaling increases pixel count but does not add detail. It makes images larger for printing or display, but won't magically add sharpness. Best for resizing small images.

Is my image uploaded to a server?

No. All processing happens locally in your browser using the Canvas API. Your images never leave your device.
