# View object metadata

Adobe Reader lets you view the metadata information of certain images, and objects within a PDF document. An image’s metadata is created in the application that made the image. You cannot edit image metadata in Reader.You use the Object Data tool to view object data of Microsoft Visio custom properties. To view object metadata, choose Tools > Data > Object Data tool. Place the pointer over an object and click when the pointer changes to a cross hair; the Object Data window displays information about the item. If the pointer doesn’t change to a cross hair, then the item doesn’t contain Visio object data.
