Convert Bedrock Seeds to Java Edition
Transform your Minecraft Bedrock Edition seeds into Java Edition compatible formats with our easy-to-use converter tool.
Minecraft’s Bedrock and Java Editions don’t always speak the same language when it comes to world seeds—especially if your seed is negative. If you want to explore the same world with friends (or just keep your favorite landscape), you’ll need to convert it. That’s what this tool is for!
Paste your Bedrock seed above and we’ll handle the rest. It’s quick, easy, and you’ll be back to building in no time.
- Positive seeds: Good news—these work the same in both versions. No changes needed!
- Negative seeds: Just add

This is the same trick Minecraft uses behind the scenes to convert 32-bit seeds to 64-bit ones.
| Bedrock Seed | Conversion | Java Seed |
|---|---|---|
| -12345 | -12345 + 4294967296 | 4294954951 |
| 98765 | Already positive | 98765 |
| -2147483648 | -2147483648 + 4294967296 | 2147483648 |
- Terrain generation may still differ slightly between versions
- Structure locations might not be exactly the same
- Some biomes may generate differently
- Village layouts and compositions might vary
- Always test the converted seed before starting a major project
This is normal due to different generation algorithms. Try exploring further from spawn.
Structure generation varies between versions. Try using /locate command to find similar structures.
Double-check the conversion math and ensure you're using the correct Minecraft version.
Understanding Minecraft Seeds: Java vs. Bedrock
What is a Minecraft seed? A seed is a unique code (number or text) that determines how your Minecraft world is generated. Entering the same seed in different versions of Minecraft can create similar—but not always identical—worlds.
Java Edition vs. Bedrock Edition: While both editions use seeds, the world generation algorithms and features can differ. Positive seeds usually work the same in both, but negative seeds and large numbers may generate different terrain. Structures, biomes, and even spawn points can vary between editions and game updates.
- Java Edition: Used on PC, Mac, and Linux. Supports mods and snapshots. World generation changes with major updates (e.g., 1.18 Caves & Cliffs, 1.20 Trails & Tales).
- Bedrock Edition: Used on Windows 10/11, consoles, and mobile. Cross-platform multiplayer. Some features and structures may appear differently than in Java.
Why do seeds sometimes look different? Each update can change how terrain, biomes, and structures are placed. Even with the same seed, a world in Minecraft 1.16 will look different from 1.20. Bedrock and Java also use different randomization for some features.
Tips for using seeds across editions:
- Always check your Minecraft version—worlds may not match after major updates.
- Negative seeds need conversion for Java/Bedrock compatibility (use the tool above!).
- Some rare seeds produce unique terrain only in one edition.
- For multiplayer, make sure everyone is on the same edition and version for best results.
