What types of files can I preview in Dropbox?

Dropbox can preview the types of files listed in this article. If a file type isn’t shown, you can still open it by downloading the file first.

We recommend searching this article for your file type by pressing control-f (Windows) or command-f (Mac) on your keyboard.

Why can’t I preview my file?

If you’re having trouble previewing a file, Dropbox may be unable to support your file type, or it might be too big to be previewed. Check the table in this article for size limits and file types that Dropbox supports.

You can also check this article for common error messages and fixes.

Notes:

Previews will be generated only for the file types available to the file owner. For example, if a user on a Dropbox Basic plan shares a .mxf file with a user on a Dropbox Professional Plan, the user on the Dropbox Professional plan will not be shown a preview, even though the Dropbox Professional plan allows previews for those file types.
Customers who have purchased the Dropbox Replay Add-On (formerly the Creative Tools Add-On) can preview files up to 150 GB in size.
