It's a universal file converter that does conversions locally on your device. There are plenty of file conversion sites, but when you use them, you’re sending your files and data to their servers. I didn’t like that and I wanted to use local tools but with a drag and drop app, so non-programmers could use it!

It supports almost any file type. 2110 conversions are currently supported with more being added as they are suggested by the community, here.
