Preview your ad or HTML page
As you're building your ad or HTML page you can preview it in your favorite browser to see how it will work and look when it's published. A preview is generated directly from Google Web Designer, and can't be saved as a separate file. To share a file, you need to publish it.
To preview your work, click the preview button at the top of the screen.
Google Web Designer recognizes the supported browsers on your system and lets you choose which of them you want to use.
To choose the browser that you want to preview your work in, click the selection arrow to the right of the preview button, and choose the browser from the pop-up list.
