A single seat license of ‘PDF Converter for Windows’ is available in Standard and Professional editions. The only difference is the PDF generating automation feature in the Professional edition. With this feature, the PDF Converter app can automatically convert documents from a watched folder to PDF files in an output folder, on-the-fly.
With the professional version, you can use 1 (one) watch folder to convert newly added files/documents into PDF files automatically. For unlimited watch folders, you need an enteprise license.
For more on this feature, refer to our other KB article – Enterprise PDF Automation.
