ConvertAPI - High-Performance File Conversion API

When I started programming, I found that document conversions from one file format to another are incredibly tricky. While digging the web, I noticed many people losing their heads about it and no simple solution that suits all. Most of the approaches I found were clumsy and outdated, so I came up with the decision to write my own conversion processor. And that's how the ConvertAPI was born. Your ideas and feedback would be greatly appreciated here. Feel free to collaborate to make this wonderful product even better!
