How PNG upscaling works
PNGs include both opaque pixels and transparent pixels. This workflow keeps alpha clean by separating the transparency, processing edges carefully, then recombining and exporting a clean PNG.
1) Alpha channel separation
The workflow separates RGB from transparency so upscaling doesn’t smear color into transparent regions.
2) Edge-aware upscaling
At the boundary between opaque and transparent pixels, edges are enhanced without adding halos.
3) Recombination & export
The processed RGB and alpha mask are recombined and exported as a clean, transparent PNG.
