ps2pdf, pdf2ps – convert between PostScript and PDF

ps2pdf [ gs–options ] [ input–file [ output–file ] ]

pdf2ps [ –e ] [ gs–options ] [ input–file [ output–file ] ]

Ps2pdf and pdf2ps convert from PostScript to PDF and back by invoking gs(1). If output–file is not specified, they write to standard output. If neither input–file nor output–file is not specified, they read from standard input and write to standard output.

Under –e, pdf2ps emits Encapsulated Postscript (eps).

The gs–options are passed to Ghostscript unaltered. The most useful option to ps2pdf is –dCompatibilityLevel=level, which sets the version of PDF to be written. The default is 1.2; 1.3 and 1.4 are also possible. Similarly, the most useful option to pdf2ps is –dLanguageLevel=level, which sets the version of PostScript to be written. The default is 2; 1 and 3 are also possible.

Ps2pdf produces output competitive with Adobe Distiller in most cases, and it accepts all the embedded PDF–generation hints that Adobe Distiller does.

Pdf2ps produces a PostScript file containing one large bitmap per page. For a more direct and smaller translation, use Adobe Acrobat's –toPostScript command–line option.



Gs's pdfwrite sometimes emits bad PDF at the default level 1.2. Adding '–dCompatibilityLevel=1.4' should cure it.
