As users increasingly shift to cloud services, devices are less likely to be pre-loaded with applications that support the multitudes of different file types that exist today and are continuing to be created. Thus, embodiments are directed to editing and sharing unsupported files through an instantly generated preview without having to install applications that support each file type and/or subscribe to services. For example, in response to detecting a user's request to access a file that is stored locally and determining a lack of a local application or previewer associated with the file, a preview that includes a presentation of the file using a registered previewer may be instantly generated. The preview may be rendered such that the file can be edited and/or shared through the previewer based on a level of editing and/or sharing functionality, respectively, where the levels of functionality are based on the user's subscription status.
