PotatoPeeler review
A focused, free utility for protected, low-risk Anvil chunk trimming.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PotatoPeeler is an open-source Java command-line utility for removing unused chunks from Minecraft Java Edition worlds. It processes Anvil region files by evaluating each chunk’s InhabitedTime against a configurable threshold, helping reduce storage use in local game saves or server worlds. The tool runs on Windows and Linux, is self-hosted, and is distributed as downloadable JAR files. It fits administrators and technical users who need targeted world cleanup rather than a general-purpose Minecraft editor.
Its strongest area is controlled cleanup. PotatoPeeler can protect force-loaded and custom-specified chunks, along with coordinate ranges and wildcards, so administrators can define areas that must remain intact. Dry-run mode allows a cleanup operation without writing changes, while separate output directories provide an alternative to immediate in-place modification. For workflows involving multiple worlds, the utility can process multiple world directories. It can also run as a Minecraft server wrapper, and it creates backups before in-place region-file writes.
PotatoPeeler is free and open source, with no paid tiers described. The published project supports Minecraft Java Edition only, and the listed platforms are Windows and Linux. A compatible Java Runtime Environment is required, so setup is better suited to users comfortable with command-line tools and Java-based downloads. The latest listed release is PotatoPeeler 1.3.0, which adds support for the newer Java Edition 26.1 save structure. Choose it for specialized, protected Anvil cleanup with dry-run and backup options; choose another tool if you need a graphical interface, broader edition support, or a different world-editing focus.
