File types that preview on dropbox.com

We add to this article frequently, so check back occasionally for your favorite file types.

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

For our advanced users

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 text files:

  • .htm and .html files do not preview in public links shared via the public folder

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, Pro, 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.
