Previewing assets using the software interface

You can use Preview to see how a digital asset that you have uploaded looks when it is viewed by a customer in their own web browser. The default embedded, cross-device viewer that is assigned to the asset is used for the Preview.
A viewer is a collection of various settings or "presets," such as the viewer display size, zoom behavior, color schemes, borders, fonts, and so forth, that determine how users view rich-media assets on their computer screens and mobile devices.
Besides using the dedicated Preview feature for video, spin sets, and image sets, you can also preview an asset by using viewer presets that you have created. Or, use image presets to preview renditions of images.
When you are on a webpage (Sites) in AEM, you cannot preview assets in Edit mode. You need to go to Preview mode by clicking Preview in the upper right-hand corner of the page.
To enable or disable viewer presets in the user interface, see Managing Viewer Presets .
