Xpdf is an open-source PDF viewer for the X Window System and Motif.[1][3] Xpdf runs on practically any Unix-like operating system. Xpdf can decode LZW and read encrypted PDFs. The official version obeys the DRM restrictions of PDF files,[4] which may prevent copying, printing, or converting some PDF files.[1] There are patches which make Xpdf ignore these DRM restrictions,[5] and these restrictions are patched out by the Debian distribution.[6]

Xpdf includes several programs that don't need an X Window System, including some which extract images from PDF files or convert PDF to PostScript or text. These programs run on DOS, Windows, Linux and Unix.[1]

Xpdf is also used as a back-end for other PDF readers frontends such as KPDF and GPDF,[3] and its engine, without the X11 display components, is used for PDF viewers including BePDF on BeOS, '!PDF' on RISC OS, on PalmPDF[7] on Palm OS[1] and on Windows Phones.[8]

Two versions exist for AmigaOS. Xpdf needs a limited version of an X11 engine called Cygnix on the host system. AmigaOS 4 included AmiPDF, a PDF viewer which is based on 3.01 version of the XPDF. However both Apdf and AmiPDF are native and need no X11.


The associated package xpdf-utils contains tools such as pdftotext and pdfimages.
