Previews give you a comprehensive summary of your long document, video, or image album. They let you see what's inside your file at a glance.

The following information about previews in Zoho Docs will help you:

  • Use the preview toolbar.
  • Edit MS Office files.
  • Know supported file formats.
  • Understand preview errors.
  • Learn the allowed file size for different file types.

  • Sharing files
  • Printing files
  • Downloading files
  • Opening files in new tab
  • Viewing files full screen
  • Zooming in
  • Rotating images
  • Viewing file properties
  • Commenting on files

The drop-down menu contains additional options:

dropdown for file preview
  • Send Mail lets you email files from the preview screen.
  • Add tags or keywords for each file to help you find them easily.
  • Use Add Task to assign items to anyone on any file.
  • Check out a file so that no one else can edit it while you're working on it.
  • Upload new versions of files and create different names for each version.


Permission settings affect the available options for shared files. For example, the preview toolbar of a read-only file will not have the share option.
