File types that preview on dropbox.com

There are many file types that can preview on dropbox.com. We update this article when we start supporting new file types, so check back occasionally to see the latest.

Preview a file

You can preview a supported file on dropbox.com in two ways:

  • Click the name of the file.
  • Click the checkbox next to the file. Then click the viewer icon (an eye) that appears.

Note: It isn't possible to edit a file from its preview on dropbox.com. Instead, you can download the Dropbox desktop app to quickly open files on your computer and edit them. If you want to edit a Microsoft Office file, try our Office Online integration.

To preview files on Dropbox using Chrome, make sure that Chrome is not set to Block third-party cookies and site data. You can adjust this setting on Chrome's Content settings page under Cookies.

Special considerations for image and video files:

  • For .psd files, we recommend saving your files with the preference to maximize compatibility.
  • Video codec created via GoToMeeting can be previewed.
  • When you save a video in your Dropbox you will be able to watch the full video from a preview page.
    • If a Dropbox Business user creates a shared link to a video, the recipient can view the entire video on a preview page. This does not apply to videos created by users on a Dropbox Business trial.
    • If a Dropbox Basic, Plus, or Business trial user creates a shared link to a video, the recipient can only view up to 15 minutes on a preview page. Recipients can download the file to their computer or add it to their own Dropbox account to view the entire video.
