"Before reaConverter, I was the ‘File Conversion Guy’ at work — a title I never asked for and definitely didn’t want. Then I found the Watch Folders feature, and suddenly I was free! Now, files convert themselves while I sip coffee and pretend I'm still working hard. My coworkers think I'm a wizard. Thanks reaConverter, for saving my sanity and boosting my fake productivity!"
