Converter Interface

Steps Panel

Positioned at the top of the Converter is the Steps Panel. Its purpose is to indicate which step in the conversion process you are currently on as well as which steps you've already completed and which are still to come.


There are five steps that are completed in the following order: Input > Output > Options > Convert > Save.

Step Navigation

If at any point during the conversion process you need to go back to a previous step, or continue forward again, you can use the arrow buttons positioned at the left and right sides of the steps panel:


Step 1: Input

The Input step page has five buttons, one for each Minecraft edition. They can be clicked to select an input world for the converter.


Step 2: Output

The Output step page also has five buttons, one for each Minecraft edition. Only one can be selected as the desired output edition. When selected, the background turns green.


Version Selector

Below each of the five buttons is a dropdown menu. These menus are for choosing the desired output version for its respective edition.



The Next buttons throughout the Converter complete the current step and move you to the next one.


Step 3: Options

The Options step page has many different controls used to change how the converter operates during the conversion. For a full breakdown of these options, visit the LINK COMING SOON documentation page.



Here you will find 3 different types of control widgets:

  • Switchers behave as simple on/off checkboxes.
  • Named Switchers can represent multiple options beyond just on or off.
  • Number Boxes are for inputting numbers.


Basic Options

The left side of this page contains the different controls for controlling basic settings for the output world. Throughout the documentation, these controls will always be referred to as basic options because they don't control very technical aspects of the conversion process.


Advanced Options

The right side of this page controls the advanced features for the conversion. These work in the same way as the basic options, however, they control more technical aspects of the conversion. Therefore, question mark icons were placed beside each option that when clicked display a message providing more information on that option (indicated here in yellow).



Step 4: Convert

The Convert step page is where the conversion actually takes place. It has the conversion type display positioned at the top indicating the input edition and output edition/version. The status text is just beneath it. Beneath that is the progress bar indicating how far along the conversion is. Lastly is the Start/Stop Conversion button.


There are 3 states during this page:

  • Ready
  • Converting
  • Cancelled

Ready State

The ready state is indicated by the Ready to Convert status text and the button reading Start Conversion. This is the final step before the conversion begins. This state exists to let you double-check your conversion type before beginning. Clicking the button will move the converter from the ready state to the converting state.

Converting State

The converting state is indicated by the status text changing with the progress of the conversion. It will display how many chunks have been converted in total as the conversion progresses. The Start Conversion button will have changed to read Stop Conversion. Clicking it will abort the conversion and move the converter to the cancelled state. Otherwise, when the conversion completes it will move to the next step.


Cancelled State

The cancelled state is indicated by the Conversion Stopped status text and red progress bar. If during the conversion the Stop Conversion button was clicked, this state will be entered. From here, the only option is to click the Start Over button to return back to step 1.


Step 5: Save

The Save step page appears after the conversion has completed. Here you will either save the converted world to your computer or discard it and start over. It looks almost identical to the previous step except it now has the Save World button. It can be clicked to bring up one of the save world dialog windows.



The Universal Minecraft Tool's converter was designed to make Minecraft world conversion as easy as possible. It guides you through every step from start to finish while still providing both basic and advanced conversion options.
