About

Hey, it's Lucas 👋

While building Read to Me, I noticed how annoying it can be to convert audiobooks. It felt like one of those problems that should be simple, but somehow isn't. And since I was running into it, I figured other people probably were too.

So, being a software engineer - naturally - my response to a mildly annoying problem was to build a solution. That is how Audiobook Converter came to be, and hopefully it makes audiobook conversions a little less annoying for you too.
