Every year thousands of users around the world save thousands of hours using reaConverter.

"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!"

"We use reaConverter in our department to handle image and document conversions for multiple teams. The Watch Folders function is brilliant — I configured different folders for different workflows, and now everything happens automatically in the background. No more manual conversions or missed files. Rock-solid performance!"
