You can preview hundreds of file types with Dropbox, depending on whether you’re previewing a file on the web, your desktop, iPhone or Android. You can view .png, .gif, .tiff, .bmp., .jpg, .jpeg, .wav and .ogg audio files, .mov and .mpg video files and .txt extensions as text files.

You can use Dropbox as a file viewer across all Dropbox plans. However, currently, only Professional plans support the preview of .mxf and .dwg.
In the event you may not want your recipient to download the file you send, you can give them ‘view only’ only access to preview, but not download, the file. If you’re a Dropbox Professional or Business customer, you can set permissions on shared links. Keep in mind that Google Docs, Sheets, and Slides allow edit access by default, but you can change the access to ‘view only’ when you create the link.
