Chunkoid

Chunkoid is a free, open-source Android app for converting Minecraft worlds and resource packs between Bedrock and Java formats without a PC. It handles conversions in either direction and supports version upgrades and downgrades across Minecraft versions from 1.8.8 through 1.21+ and 26.x. The app can decrypt NetEase-encrypted worlds. Conversion controls include logs that show steps, output management, dimension pruning, a background wake lock, and a low-memory mode intended to reduce crashes. Supported inputs include folders, ZIP files, MCWORLD files, and resource packs. Chunkoid requires Android 8.0 or later; Android 10 or later is recommended. The download page also recommends at least 2 GB of free storage and 6–8 GB or more of RAM. The listed Android release is v2.0.0 at 63.7 MB. The project is licensed under GNU GPL v3.0, and its about page says maintenance was transferred to DICECAN (EncoreTeam). For technical discussion and bug reports, the project directs users to its QQ community.

Chunkoid suits Android users who need to convert Minecraft worlds or resource packs between Java and Bedrock without a PC. It also suits users handling supported version changes or NetEase-encrypted worlds.

Chunkoid is a free Android app for converting Minecraft worlds and resource packs between Java and Bedrock editions, as well as across supported game versions. It suits players who want to move or adapt worlds on a phone rather than use a PC. Its broad conversion range is compelling, provided the Android device meets its storage and memory recommendations.

Overview

Chunkoid brings world conversion, resource-pack conversion, and version changes into one Android app. It supports Java-to-Bedrock and Bedrock-to-Java workflows, can decrypt NetEase-encrypted worlds, and covers Minecraft versions from 1.8.8 through 1.21+ and 26.x. That makes it a focused option for players managing worlds across editions or versions, not a general-purpose Minecraft utility.

The project is licensed under GNU General Public License v3.0. Its about page says the app was donated and transferred to DICECAN (EncoreTeam) for ongoing maintenance. Technical discussion is directed to a QQ community; bug reports should include error logs and steps to reproduce the issue.

Key features

• Two-way world and version conversion: Convert between Java and Bedrock formats, and upgrade or downgrade supported worlds. The wide version span is useful for older saves and newer releases, though conversion needs can vary by world.
• Resource-pack conversion: Convert packs between Java and Bedrock editions, making Chunkoid more useful than a world-only converter for players moving a broader set of content.
• NetEase decryption: The app includes decryption for NetEase-encrypted worlds, a specific advantage for users working with those saves.
• Conversion controls and logs: Logs expose conversion steps, while output management and dimension pruning give users control over results. A background wake lock supports longer work, and low-memory anti-crash mode is intended for devices under memory pressure; neither removes the need to meet the app's hardware recommendations.
• Supported inputs: The download page lists folders, .zip files, .mcworld files, and resource packs. The latest listed Android release is v2.0.0 at 63.7 MB.

Pricing

Chunkoid is free: the Free plan costs nothing and provides the Android app. There is no free trial because the app is already free. There are no paid tiers, seat counts, or quotas described; the practical limits are device compatibility and the work the app supports.

Platforms

Chunkoid runs on Android 8.0 or later. Android 10 or newer is recommended, along with at least 2 GB of free storage and 6–8 GB or more of RAM. Those requirements make it a better fit for a reasonably capable phone or tablet than an older, storage-constrained device. It is designed to convert worlds without a PC.

Who it's for

Choose Chunkoid if you need to convert Java and Bedrock worlds or resource packs directly on Android, especially if NetEase decryption, version changes, or conversion logs matter to your workflow. Look elsewhere if you need a Windows, Mac, Linux, or browser-based workflow, or if your Android device falls short of the recommended resources.

Pros and cons

• Pro: Free, two-way world and resource-pack conversion keeps several common migration tasks in one Android app.
• Pro: Support for versions from 1.8.8 through 1.21+ and 26.x covers a broad range of older and newer saves.
• Pro: Logs, output management, dimension pruning, and low-memory mode provide useful visibility and controls during conversion.
• Con: Android-only support rules it out for users who need a desktop or web workflow.
• Con: The recommended 6–8 GB or more of RAM and 2 GB of free storage may exclude lower-spec devices.

Alternatives

Minecraft World Converters is a useful starting point if you want to compare tools by workflow and platform.

• LCEStudio is a free Windows option if you need a desktop tool rather than Android.
• MC Version Converter is a free source-code option for Linux, macOS, or Windows when the task is converting Java Edition 26.x worlds to versions 1.18.2–1.21.11.
• Java2Nukkit World Converter is a free desktop choice for Java Edition 1.15.2 worlds when optimized worlds and Java 1.8+ suit your setup.
• Server to Singleplayer World Converter is a free browser-based option for Java and Bedrock world conversion.
• WorldSwitch suits browser users with smaller uploaded files: its Mini plan is free per conversion for files up to 70 MB, while Small costs €1.99 per conversion for files from 71 MB to 300 MB.
• Bridger is a free, open-source desktop alternative for Linux, macOS, or Windows.
• Chunker is a free, open-source option for Linux, macOS, web, or Windows.
• je2be is a free option for web or Windows users.

Verdict

Chunkoid is the right pick for Android users who need free, bidirectional Java–Bedrock world and resource-pack conversion, with version changes and NetEase decryption in the same tool. Its main reason to look elsewhere is its narrow platform reach: choose a desktop or browser alternative if you cannot or do not want to convert on a sufficiently capable Android device.
