Sharper, larger anime art and illustrations
Anime and illustration are made of confident outlines and flat colour fills. A good anime upscaler keeps those lines the same weight and the colour boundaries hard, instead of turning them into blurry gradients.

Why Deep Enhance suits anime artwork
Traditional interpolation averages neighbouring pixels, which softens every inked line. Deep Enhance uses Real-ESRGAN, which predicts where an edge should be at 4× resolution, so line art stays crisp and cel-shaded areas stay flat when you upscale anime frames.
Keep sharpening low
Line art already has strong edges; extra sharpening causes bright halos. Lanczos with sharpness under 30 is a good non-AI alternative.
Export as PNG
Flat colour areas compress poorly as JPG and pick up blocky noise. PNG keeps illustrations clean.
