PDFing runs on a Microsoft® Windows PC and receives spooled-files sent to it by standard OS/400 and i5/OS commands. These spooled-files are converted to PDF and other file formats, including MS Excel. PDF files produced by PDFing may be saved to specified storage-locations, printed or sent as email attachments to selected recipients. The output PDF may be enhanced by applying graphic images , applying the page(s) of other PDF files and changing font sizes. Spooled-files may also be split or "burst" into a series of separate PDF files each with different destination address. PDFing complies with the following IBM standards: i5/OS and OS400 version 3.1 or later, *SCS, *AFPDS and *USERASCII spooled-files, the Internet standard LPR/LPD for receiving spooled-files, the Internet standard SMTP for sending email and the PDF specification from Adobe®. PDFing can be a server for any (reasonable) number of concurrent OS400 jobs on any number of AS400 or iSeries machines.

PDFing is supported by PDFing on all editions of Windows 10.
