PNG Transparency Cleaner

Clean up the semi-transparent fringing and noise that often surrounds exported PNG assets. The tool applies two thresholds to the alpha channel: any pixel below the low threshold becomes fully transparent, any pixel above the high threshold becomes fully opaque, and pixels in between keep their smooth alpha for clean anti-aliased edges.

Features

Independent low and high alpha thresholds
Preserves smooth alpha in the middle range
Transparent-checkerboard preview
100% local processing

Use cases

Clean up sticker exports
Remove halos from chromakey results
Tighten edges on cut-out portraits
Prepare assets for sprite atlases
