What types of files can I preview on dropbox.com?

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

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.

Supported file types include:

Document files

.doc, .docx, .csv, .pps, .ppsx, .ppt, .pptx, .rtf, .xls, .xlsx

Image and video files

.ai, .bmp, .eps (web only), .gif, .jpg, .jpeg, .png, .psd, .tiff, .tif, .svg

.3gp, .3gpp, .3gpp2, .avi, .dv, .flv, .m2t, .m4v, .mkv, .mov, .mp4, .mpeg, .mpg, .mts, .ts, .vob, .wmv

Special considerations for image and video files:

  • When saving .psd files you can set a preference to maximize compatibility, which is recommended
  • Video codec created via GoToMeeting can be previewed
  • There is no file size limit for video file previews
  • When you save a video in your Dropbox you will be able to watch the full video from a Dropbox preview page

    • Dropbox Business users who receive a shared link to a video can view the full length on a preview page
    • Dropbox Basic and Pro users who receive a shared link to a video can view the first 15 minutes on a preview page (these users can download the file to their computer to view the full length)

Audio files

.aac, .flac, .m4a, .mp3, .oga, .wav, .wma

Code and text files

.c, .coffee, .cpp, .css, .diff, .htm, .html, .js, .java, .less, .markdown, .md, .mdown, .mkdn, .php, .py, .rb, sass, .scss, .sh, .sql, .txt, .vb, .xhtml, .xml
