Compress PNG images while preserving transparency and quality

PNG is the go-to format for graphics that need transparency or pixel-perfect detail, but these files tend to be much larger than JPEGs. RoundCut optimizes PNG compression in the browser, trimming excess data while keeping alpha channels and crisp edges intact.

Great for web graphics, logos with transparent backgrounds, screenshots for documentation, UI design assets, game sprites, and icon sets.
