Standard Scratch projects often compress assets to save space. By converting your project to a ZIP, you can manually "inject" higher-quality assets: High-Res Textures
When dealing with "quality" in the context of ZIP and SB3, the following features are key:
Converting a ZIP file to SB3 is primarily a matter of , as SB3 files (used by Scratch 3.0 ) are essentially ZIP archives containing project data. To ensure "extra quality" or a successful deep post-conversion, you must verify the internal structure of the archive. Core Conversion Steps
