Convert SB2 to EXE

A Windows user may need to distribute a Scratch project as a file that launches by double-clicking, without requiring the Scratch editor or a browser. Packaging the project as an .exe also provides an offline Windows copy for classrooms, demonstrations, or archival use.

What the SB2 format is

.sb2 is the project format used by Scratch 2.0. It is a ZIP-based package containing block scripts, sprites, costumes, sounds, stage data, and project metadata. Scratch 2.0 users, educators, and archives still encounter SB2 files, especially in projects downloaded before Scratch 3.0 became standard.

What the EXE format is

.exe is a Windows Portable Executable file. A packaged Scratch application can launch by double-clicking and can include the project, its assets, and a Scratch-compatible runtime, so the recipient does not need the Scratch editor. This is runtime packaging, not native compilation: the Scratch blocks are not rewritten as native Windows code.

An EXE is intended for Windows. macOS and Linux require their own package or export format, and an EXE normally cannot run on those systems without a compatibility layer or virtual machine.

How to convert SB2 to EXE

Use TurboWarp Packager

TurboWarp Packager is the practical current option for creating a Windows executable from a Scratch project. It is available as a browser-based packager and as a desktop application. The web version is convenient for non-sensitive projects; the desktop version avoids uploading the project.

1. Keep a backup of the original .sb2 file.
2. Open TurboWarp Packager and use its project-open or upload control.
3. Select the .sb2 file. Verify that the sprites, scripts, costumes, sounds, stage, and required extensions load correctly.
4. Choose the Windows executable output, usually shown as a Windows or .exe packaging format.
5. Set available application options such as the program name, icon, window dimensions, fullscreen behavior, and visible controls.
6. Choose the package or export command and save the generated .exe.
7. Test the file on a Windows computer that does not have the original project or Scratch editor installed.

Menu names and available packaging formats can change between TurboWarp releases, so use the current output label shown by the installed packager rather than relying on an old menu path.

Convert through Scratch 3 when necessary

If the packager does not accept a particular SB2 file, open it with the Scratch 3 online editor using its project-upload command. Scratch can import many SB2 projects and then save or download the result as .sb3. Load that .sb3 file into TurboWarp Packager and select the Windows executable output.

This intermediate conversion is not guaranteed to preserve every Scratch 2 feature. The Scratch 2 Offline Editor can also help inspect or recover an old project, but it is legacy software and is not itself a current SB2-to-EXE exporter.

Compatibility and quality limits

The generated application contains a runtime and the project assets, so it is usually much larger than the original .sb2 file. Packaging does not improve graphics or audio quality; imported assets retain the limitations and compression of the source project.

Test projects that use Scratch 2 extensions, webcam or microphone access, cloud variables, networking, external URLs, broadcasts tied to timing, or browser-specific behavior. A packaged application may lack browser permissions, online services, or extension support. Cloud variables generally require a compatible online backend and should not be assumed to work offline.

Check the project at its intended window size and frame rate, and test keyboard, mouse, sound, fullscreen, save-data, and network behavior on the target Windows versions. Windows may show an unknown-publisher warning because a self-generated EXE normally has no code-signing certificate.

No trustworthy general-purpose converter is needed when TurboWarp Packager is available. Avoid uploading private projects to unknown online conversion sites: an SB2 package can contain unpublished media, personal information, or embedded credentials.
