Files with the following extensions can be openend immediately after upload: swf, jpg, jpeg, png, gif, mp3, mp4, flv, m4v, f4v, f4a, f4b, f4p, mov (most), mp4v, m4a, 3gp (most), 3g2 and aac.

Out of that list you can choose to convert the following to a smaller, optimized size: mp4, flv, mov

Other filetypes can either be uploaded and converted, or just uploaded (and shared with others for download, for example).

Filetypes that can be uploaded and converted:
Office: doc, docx, ppt, pptx, pps, ppsx, xls, xlsx and also pdf, txt, and rtf
Video: avi, wmv, mpg, mpeg, asf, asx, fix, mkv, xvid and the filetype mentioned in the previous question (mp4, flv, mov)
Audio: wma, wav, wave, aif, aiff, mpa and ogg

For PowerPoint files

  • Make sure you do not include macros on your sildes. For safety reasons we have to disable all macros and that should work fine, but there can be cases where the presence of macros will cause the conversion to cancel.
  • Make sure you do not embed ActiveX components in your slides (such as external video). This causes stability issues with the converter.
  • Make sure you do not rely on external resources, such as CSS. Whilst this should usually not cause any issues with the conversion, we have seen cases which made the file nonconvertible.
