Chunkoid

Chunkoid is a free Android utility for players who need to move Minecraft worlds or resource packs between Java and Bedrock, or adjust a world’s game version. Its main advantage is handling those jobs on a phone; the Android-only platform and substantial memory recommendation make device fit the key caveat.

Overview

Chunkoid combines two-way Java–Bedrock world conversion with version upgrades and downgrades, resource-pack conversion, and decryption for NetEase-encrypted worlds. That breadth makes it a useful single-purpose tool for players managing saves across editions, but it is not an option for someone who needs a desktop workflow.

The app is open source under GNU General Public License v3.0. It is maintained by DICECAN (EncoreTeam) after being donated and transferred to them. Technical discussion goes through a QQ community, and bug reports should include error logs and reproduction details, a practical route for users who can supply enough context to diagnose a problem.

Key features

• World and version conversion: Convert worlds in either direction between Java and Bedrock, and upgrade or downgrade supported Minecraft versions, from 1.8.8 through 1.21+ and 26.x. This range suits players working with older saves as well as newer versions, though users should confirm their intended version falls within the supported span.
• Resource packs and encrypted worlds: Bidirectional Java–Bedrock resource-pack conversion and NetEase-world decryption extend the app beyond world files. It is a stronger fit for players handling several kinds of Minecraft content than a converter limited to worlds.
• Conversion controls: Logs expose the steps in a conversion, while output management, dimension pruning, a background wake lock, and low-memory anti-crash mode provide ways to manage the process. These controls are useful on a phone, but the low-memory mode does not remove the app’s recommended RAM threshold.
• Input formats: The download page supports folders, .zip files, .mcworld files, and resource packs, covering common packaged and folder-based inputs.

Pricing

Chunkoid has one plan: Free — free. The Android app includes its conversion features without a paid tier, making it an uncomplicated choice for an Android user who needs these tools. There is no free trial because the app is free; no seat or conversion quota is attached to the plan.

The trade-off is platform and device dependence rather than a cheaper feature-restricted plan. Chunkoid requires Android 8.0 or later, recommends Android 10 or later, and suggests at least 2 GB of free storage and 6–8 GB or more of RAM. The latest listed Android release is v2.0.0 at 63.7 MB.

Platforms

Chunkoid runs on Android only. Android 8.0 is the minimum, while Android 10+ is recommended; the suggested 2 GB of free storage and 6–8 GB or more of RAM are meaningful considerations for large worlds or devices with limited headroom. Choose another converter if you need to work from Windows, macOS, Linux, or a browser.

Who it's for

Chunkoid is best for Android users who want a PC-free way to convert Java and Bedrock worlds, change supported Minecraft versions, or convert resource packs. Its decryption and conversion controls add value for users with those specific needs. It is a poor fit for users without a compatible Android device or enough storage and memory, and for anyone whose workflow depends on a computer or browser.

Pros and cons

• Pro: One free app handles two-way world and resource-pack conversion, version changes, and NetEase-world decryption.
• Pro: Logs, output management, dimension pruning, and low-memory mode give users practical conversion controls.
• Con: Android is the only supported platform, so desktop and browser users need another tool.
• Con: The recommended 6–8 GB or more of RAM and 2 GB of free storage may rule out constrained phones.

Alternatives

Minecraft World Converters is the broader directory for comparing tools in this category.

• Chunker is worth considering if you need Linux, macOS, Windows, or web access; it is also free and open source under the MIT license.
• MC Version Converter is a desktop choice for Java Edition 26.x worlds that need conversion to versions 1.18.2–1.21.11. It is free, but its stated scope is narrower than Chunkoid’s two-way edition and resource-pack conversion.
• Bridger is another free desktop option for Linux, macOS, and Windows, with its code and development hosted through GitHub.
• Java2Nukkit World Converter suits a narrower Java-to-Nukkit workflow: it targets Minecraft Java Edition 1.15.2, requires optimized worlds and Java 1.8+, and is free under the MIT-licensed plan.
• je2be is a free alternative for web or Windows users; its web repository is released under AGPL-3.0.
• LCEStudio is a free Windows option for users whose needs fit that platform.
• Server to Singleplayer World Converter is a free browser-based choice for Java and Bedrock world conversion.
• WorldSwitch is a web alternative with a free Mini plan for uploads up to 70 MB per conversion, without sign-up; choose it when browser access and that file limit suit your workflow.

Verdict

Choose Chunkoid if you want a free, Android-based way to convert Minecraft worlds and resource packs between Java and Bedrock, with version conversion and useful process controls in the same app. Look elsewhere if you need desktop or browser support, or if your phone falls short of its storage and memory recommendations.
