OverdrawSmith

OverdrawSmith is a sprite atlas optimizer that counts every wasted texel in your atlas.

Upload your atlas PNG and it finds transparent pixels inside sprite frames, oversized padding eating your texture budget, and pixel-identical duplicate sprites you could merge. Then it renders a texture overdraw heatmap showing exactly where your fill-rate bleeds, and hands back ranked repack suggestions with honest projected savings — plus a pre-trimmed packing list your atlas tool can import. OverdrawSmith also interchanges with Atlasmith's real exporter format, so it drops straight into an existing pipeline.

Everything runs offline in a single HTML file: your art never leaves the tab.

This is the free demo: 1 atlas analysis, with exports locked. Ready for unlimited analyses and all exports? Upgrade to OverdrawSmith Pro: https://theluckyduck666.itch.io/overdrawsmith-pro
