Adobe Spark is predominantly a web-based application, which means that its full functionality typically requires an internet connection to access its features, templates, and resources. However, Adobe Spark does have mobile applications that allow users to create and edit projects on their smartphones and tablets. While these mobile apps may offer some offline capabilities, certain features, such as template browsing and the ability to save new elements from the web, may be unavailable without an internet connection.
For the best experience and to access all the available assets, it is generally recommended to use Adobe Spark while online. Users looking to find specific details about offline capabilities or updates should consult the official website, as it may have the most current information regarding functionality and any changes that might enhance the offline experience.
