Understand converter limits and browser memory

Input size, selected volume, axis length, browser RAM and GPU capability all affect whether a conversion can finish.

01

What to do

  1. Input files are limited to 200 MB.
  2. A .schem export supports up to 200 million positions and 32,767 blocks on each axis.
  3. Very old pre-palette chunks and uncommon external or LZ4 region chunks are not converted.
02

Privacy and reliability

Files are parsed on your device. In the viewer, the original is also kept in your private library after the storage notice and stays private until you publish it; the standalone converter never uploads anything.

TipKeep a backup of the original. Browser conversion is convenient, but it does not replace world backups or source control.
