NetherLink

Convert Overworld <> Nether coords and map linked portals - fully offline.

NetherLink helps you link Minecraft portals without guesswork.

Convert coordinates between the Overworld and the Nether using the game’s 8:1 horizontal scale (Y stays the same). Save portals, see which ones actually link, and visualize routes in a diagram or 3D preview.

Features • Instant Overworld ↔ Nether conversion • Copy and share coordinates • Calculation history • Portal Network: save portals, mutual vs one-way links, ghost “new portal” targets • Link diagram with pinch-zoom and pan • Optional 3D preview (can be turned off in Settings) • Export / import portal backup JSON • Works fully offline — no account, no tracking
