Synopsis

pdftoppm [options] PDF-file PPM-root

Description

Pdftoppm converts Portable Document Format (PDF) files to color image files in Portable
Pixmap (PPM) format, grayscale image files in Portable Graymap (PGM) format, or monochrome image files in Portable Bitmap (PBM) format.

Pdftoppm reads the PDF file, PDF-file, and writes one PPM file for each page, PPM-root–nnnnnn.ppm, where nnnnnn is the page
number.

Configuration File

Pdftoppm 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, /etc/xpdf/xpdfrc. 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.
