Why convert DDD to PDF?
A .ddd file is a control or configuration file inside Adobe Acrobat Distiller's PostScript-to-PDF pipeline; the actual document content lives in an accompanying PostScript (.ps) file. .pdf is the intended output of the whole workflow - it is portable and viewable on any device, while PostScript requires a specialized renderer.
How to convert DDD to PDF
Adobe Acrobat Pro (Distiller) APP
Open Distiller via Acrobat Pro, set the PDF settings, then drag the PostScript (.ps) file onto the Distiller window or go to File > Open to process it; the PDF is written to the output folder.
Ghostscript FREE
Run ps2pdf input.ps output.pdf on the PostScript file; Ghostscript does not use or need the .ddd file and works free on Windows, macOS, and Linux.

- The .ddd file is not the document - if you received only a .ddd with no accompanying .ps file, there is nothing to convert; the PostScript source must be present.
- In a watched-folder Distiller setup, the .ddd is folder configuration; place the .ps file in the In subfolder and Distiller writes the PDF to the Out subfolder.
- Standalone Distiller Server was discontinued by Adobe; Distiller now ships exclusively inside Acrobat Pro.
