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!

reaConverter's automation tools have completely changed how I manage my projects. I often work with large batches of illustrations and used to spend hours converting and organizing them. Now, with Watch Folders, I just set the rules once and everything is handled automatically, exactly how I need it. This is pro-level automation made simple.
