pdftoppm

Convert PDF document pages to portable Pixmap (image formats). More information: https://manned.org/pdftoppm.

Specify the range of pages to convert (N-first page, M-last page):

pdftoppm -f {{N}} -l {{M}} {{path/to/file.pdf}} {{image_name_prefix}}

Convert only the first page of a PDF:

pdftoppm -singlefile {{path/to/file.pdf}} {{image_name_prefix}}

Generate a monochrome PBM file (instead of a color PPM file):

pdftoppm -mono {{path/to/file.pdf}} {{image_name_prefix}}

Generate a grayscale PGM file (instead of a color PPM file):

pdftoppm -gray {{path/to/file.pdf}} {{image_name_prefix}}

Generate a PNG file instead a PPM file:

pdftoppm -png {{path/to/file.pdf}} {{image_name_prefix}}
