Xpdf is an open source viewer for Portable Document Format (PDF) files. The Xpdf distribution also includes a PDF text extractor, PDF-to-PostScript converter, and various other utilities. Xpdf runs under the X Window System on UNIX, VMS, and OS/2. The non-X components (pdftops, pdftotext, etc.) also run on Win32 systems and should run on pretty much any system with a decent C++ compiler. Xpdf is designed to be small and efficient. It can use Type 1, TrueType, or standard X fonts.
