Filestar*

Filestar was created to make everyday work with all kinds of files easier. It is software for file conversion and other things you would like to do with files. You can convert, merge, split, transform, compress or extract one or many files with a few simple clicks. This desktop application has over 30,000 skills available.

Add your preferred files, select the desired operation or define a new "skill" for the application.

The available operations offered by the program are aptly named "skills" and in case the right one is not found for the specified files, a new one can be "suggested" which directs the new skill to the developer feedback program.

Filestar* supports 819 different file types.

Limitations in the free version: the Freemium version only allows users to perform 10 conversions per month.
