What types of files can I upload to Koofr?

You can upload any type of file to Koofr. There are no limits.


You can preview the majority of RAW image files (NEF, CR2, etc.) and see the thumbnails for HEIC images in Koofr.

You can also see thumbnails of many popular video file formats as well as see two possible icons on top of them. The play button on the video files that are playable in the browser and a video icon on top of the video files that will be downloaded on click. The Koofr webapp supports playback of all video formats that are supported for playback in the browser.
