I made an app that converts almost any file.

Now it does more conversions than any other app

I made howtoconvert.co

It’s a universal file converter that performs conversions locally on your device.

It does over 3000 document, video, image and audio conversions. How? By letting you run multiple command-line file conversion tools from a simple drag and drop app (imagemagick, libreoffice, ffmpeg and pandoc).

You don't have to touch the command-line to use them.

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. The alternatives are command-line tools that run locally. I wanted to use these tools but with a drag-and-drop app so non-programmers could use it.
