Linux / Unix Command: pdftopbm
Command Library


pdftopbm - Portable Document Format (PDF) to Portable Bitmap (PBM) converter (version 2.01)  


pdftopbm [options] PDF-file PBM-root  


Pdftopbm converts Portable Document Format (PDF) files to black-and-white image files in Portable Bitmap (PBM) format.

Pdftopbm reads the PDF file, PDF-file, and writes one PBM file for each page, PBM-root-nnnnnn.pbm, where nnnnnn is the page number.  


Pdftopbm reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /etc/xpdfrc (but this location can be changed when pdftopbm is built). See the xpdfrc(5) man page for details.  


Many of the following options can be set with configuration file commands. These are listed in square brackets with the description of the corresponding command line option.
-f number
Specifies the first page to convert.
-l number
Specifies the last page to convert.
-r number
Specifies the resolution, in DPI. The default is 150 DPI.
-opw password
Specify the owner password for the PDF file. Providing this will bypass all security restrictions.
-upw password
Specify the user password for the PDF file.
Don't print any messages or errors. [config file: errQuiet]
Print copyright and version information.
Print usage information. (-help and --help are equivalent.)


xpdf(1), pdftops(1), pdftotext(1), pdfinfo(1), pdffonts(1), pdfimages(1), xpdfrc(5)
