Adobe Acrobat Distiller is a computer program for converting documents from PostScript format to Adobe PDF (Portable Document Format), the native format of the Adobe Acrobat family of products. It was first shipped as a component of Acrobat in 1993. Acrobat 4, in 1999, added preset configuration files to Distiller, and Acrobat 5, in 2001, added improved color management. Originally a separate application, Distiller eventually became incorporated into a printer driver for creating PDF files that preserved the printed appearance of documents from other applications.
