What file types can I preview in Dropbox?

When you preview a file in Dropbox, you can view, comment on, and share files without downloading them. However, you can’t edit a file from a preview. 

If a preview doesn’t load, or doesn’t load correctly, your file is still accessible. You can open the file by clicking the Open with… button or by downloading it.

See the table in this article for a list of supported file types that preview with Dropbox both online and in the app. 

What if I can't preview my file? 

If you’re having trouble previewing your file, you can check this article for common error messages and fixes. 

Supported file types that preview

Because the list of file types is long, we recommend searching this article for your file type by pressing control-f (Windows) or command-f (Mac) on your keyboard.
