Frequently asked questions
Can upscaling truly improve quality?
Upscaling increases pixel dimensions and applies interpolation to add detail. Results are best for moderate enlargements (2x). Very large enlargements may show softness.
What is HD mode?
HD mode applies additional sharpening and edge-enhancement after upscaling to produce clearer, crisper results.
What is the maximum upscale factor?
The tool supports 2x and 4x upscaling. For best quality, 2x is recommended.
Will the file size increase?
Yes. Doubling dimensions roughly quadruples the pixel count and file size. 4x upscaling increases pixel count by 16x.
