What file types can I preview in Dropbox?

You can sync any type of file to your Dropbox account. However, only certain file types can be previewed on dropbox.com or the Dropbox mobile apps. This article lists those file types.

Before you get started:

  • You can search this article for a file type by pressing control-f (Windows) or command-f (Mac) on your keyboard
  • We update this article when we start supporting new file types, so check back occasionally to see the latest
  • If a preview doesn’t load, or doesn’t load correctly, you can download the file on dropbox.com or open it in another app on your phone or tablet
