"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."

Chloe M.

Freelance Illustrator

"My photography business relies on fast, accurate processing of images. With reaConverter’s Watch Folder, I drop my RAW photos into a folder and they’re instantly converted to high-res JPEGs with custom naming and watermarking. It’s streamlined my post-processing more than I imagined possible."

Emily R.

"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!"
