Convert coordinates between the Nether and the Overworld (÷8) plus tips for linking portals.
Travelling through a portal into the Nether changes the world's scale: X and Z coordinates are divided by 8. The return trip multiplies them by 8 again.
Y is not scaled, but it must fall inside the valid range: 0–128 in the Nether, and −64 to 320 in the Overworld from 1.18.
The tool converts the coordinates, validates the height and suggests safe spots for the destination portal.
Choose the travel direction: Overworld to Nether, or back.
Enter the X, Y and Z coordinates.
Get the converted destination coordinates and a ready teleport command.
Optionally use the X suggestions — a portal needs a 4×5 frame and a roof.
Only the horizontal plane is scaled. Height carries over unchanged, but is bounded by the world's limits.
Portals standing at the same X and Z in their respective worlds link automatically. An offset on any axis breaks the link.
The tool raises the value to the valid minimum — there must be at least two blocks of clearance under a portal or it won't activate.
X and Z are divided (or multiplied) by 8. Y is unchanged but must land within the world's height.
