Google Web Designer is a free, professional-grade HTML5 authoring tool. We launched a completely revamped version of the product in August, 2014. The launch included updated Events, Timeline and Components functionality, as well as improved integrations with other Google products, such as Google Drive, DoubleClick Studio, AdWords and DoubleClick Campaign Manager. This video highlights the capabilities of the updated product.
