.sb downloader downloads Scratch 1 (sb), Scratch 2 (sb2), or Scratch 3 (sb3) projects. Just paste the project's ID or URL into the input below and press the download button.
Legacy version of projects
The "legacy version" of a project is the last version of the project before it was modified with Scratch 3. This is usually only available for projects created before January 2, 2019.
When Scratch 3 was released, existing projects weren't converted to sb3 files, but re-saving a project will always convert it to an sb3. Sometimes this causes issues because the conversion process isn't perfect, which is when downloading the legacy version can be useful.
Unshared projects
