Out-of-the-Box Asset Types

Assets in Contentstack provides a comprehensive set of system-defined asset types out of the box. Each asset type maps to a MIME type and file extension, giving your team immediate support for standard file formats without the need for additional configuration.

You can associate these asset types with fields to capture metadata relevant to your workflows.

The following categories include supported asset types, their MIME types, and file extensions.

Note Some file types are flagged as restricted (for example, .exe, .sh, .bat, .php, .js, .py) because they may introduce security risks or require special handling. These formats are blocked by default to prevent malicious uploads. Administrators can explicitly enable them in settings if business requirements demand it.

Once enabled, they behave like any other type, but you should use them with caution.
