Anvil to LevelDB Converter
Source | Report Issue | Chat

This is a converter between Anvil and LevelDB, which are the world save formats used on the Java and Pocket Editions respectively. The Nukkit and FAWE API are used for conversion.

What is currently supported:
- Remaps Blocks and rotation
- Copies most block NBT
- Copies level.dat

Some things may not work, so please let me know and I'll do my best to fix it.
Note: I do not check PMC regularly, please contact me on Discord or GitHub (links above).
Progress: 100% Complete

You should consider making an android app :) It would be quite useful... Anyway, very great and cool tool, really helped me :)
If your World is HUGE in size you need to use .bat file to run the program with more than 4GB of ram IF you even have more than 4GB of ram. if you don't know how much RAM your computer has. DO NOT COMPLAIN IF THE PROGRAM DOESN'T WORK.
I've tried multiple times to use this but I keep getting this error




(FAWE) [ERROR] Conversion failed, you will have to do it manually (Nukkit server + anvil2leveldb command)




I've rebooted my computer twice like someone else who had the problem attempted but it didn't help.

It would be cool if it would convert loottables and things like that.
It just stays on the loading screen. please help
Can the inventory be converted too? if you can do chests of course you can go into the nbt data of the player and do it too right?anyways, perfect!!! Try making it convert texture packs too? That'll make this amazing

Yes, it will (or should) convert NBT data from chests with items in them. But what you are asking for with converting the texture packs is up to the authors. That is not the point of this thread and tool. The point is to convert worlds to other platforms that have Minecraft.

There has never been a better time to convert worlds to other platforms for Minecraft! Seriously, the closest we got to this was MCEdit being able to edit old pocket edition worlds, but consoles too?? This is amazing, with help from Microsoft of course from them making the bedrock engine.
Dude when I press convert world it's stuck at Downloading levedb.jar and mappings (~4MB), please wait... and does not move
Fixed it by redownloading

I had the same problem with my world. to fix it, open cmd, write "java -jar -Xmx4G " without pressing enter, and with a space after G, then drag and drop the jar file into the cmd window, and press enter. That way you increase the amount of ram that program can access, which increases the heap space. Ofc, you can change the 4 to any number you want.
The program just crashes or refuses to work after you do this...

Then you are doing something wrong, it's a standard java argument.
I'm using macOS X High Sierra and when I do the thing(I copy-paste) It's stuck at Downloading leveldb and mappings(~4MB) Please Wait
Awesome work - looking forward to seeing this develop

Double clicking the jar should open the GUI.
