Asset Catalog Tinkerer lets you open asset catalog files (
.car) and view the images that they contain. You can also copy and export individual images out or export all images from an asset catalog.
You can also install it with Homebrew by running
brew install asset-catalog-tinkerer!
Asset Catalog Tinkerer was designed with images in mind, so it doesn't support some of the more modern asset catalog features, such as PDFs, SVGs, or colors. It may or may not be updated in the future to support those.
The app also includes a QuickLook PlugIn so you can see previews of asset catalogs in QuickLook.
The app can open any
.car file, usually located within an app's
Once you have an asset catalog opened, you can drag individual assets out or export the entire catalog / selected images to a directory.
Since version 2.2, Asset Catalog Tinkerer can now read theme store files, not only catalog files.
Theme store files contain assets for UI components, you can find examples of them in
/System/Library/CoreServices/SystemAppearance.bundle. The app also supports ProKit's theme stores found inside
LunaKit.framework and other folders within pro apps.
