What is a WB file?

A WB file is a development project created by Web Blox, a modified version of MIT Scratch 1.4. It contains a webpage created using the Scratch programming language. WB files can be opened only in Web Blox, and not in the default version of Scratch.

Scratch is a block-based development environment used by children (and other novice programmers) learning how to code. Web Blox is a version of Scratch 1.4 that has been modified to allow developers to create HTML webpages, using custom Scratch blocks.

While the default version of Scratch 1.4 saves developers' projects as .SB files, Web Blox saves developers' projects as WB files. This custom extension denotes that the project was created by (and can be opened only by) Web Blox.

How to open a WB file

You can open a WB file with Web Blox (Windows). To do so, select File → Open from the program's menu bar. Then, navigate to and open your WB file.

How to convert a WB file

You can use Web Blox to convert the webpage a WB file describes to an .HTML file, which you can then open in your web browser (or any other program that supports HTML files). To do so:

  1. Open your WB file with Web Blox.
  2. Select Compile → Compile.
  3. When the Compiler window appears, click Compile.

Web Blox will then save the HTML version of your webpage in the same folder as your WB file.
