1. Convert PDF Document to Image

The syntax for converting an entire pdf is as follows:

$ pdftoppm -  
$ pdftoppm -  

In the example below, the name of my document is Linux_For_Beginners.pdf and we will convert it to PNG format and name the images as Linux_For_Beginners.

$ pdftoppm -png Linux_For_Beginners.pdf Linux_For_Beginners


Each page of the PDF will be converted to PNG as Linux_For_Beginners-1.png, Linux_For_Beginners-2.png, etc.

2. Convert Range of PDF Pages to Images

The syntax for specifying range is as follows:

$ pdftoppm - -f N -l N  
$ pdftoppm - -f N -l N  

Where N specifies the first-page number to covert and -l N for the last page to convert.

In the example below, we will convert pages 10 to 15 from Linux_For_Beginners.pdf to PNG.

$ pdftoppm -png -f 10 -l 15 Linux_For_Beginners.pdf Linux_For_Beginners

The output will be images named Linux_For_Beginners-10.png, Linux_For_Beginners-11.png, etc.

4. Adjust DPI Quality to Conversion

Pdftoppm converts PDF pages to images with a DPI of 150 by default. To adjust, use the rx number which specifies the X resolution, and -ry the number which specifies the Y resolution, in DPI.

In this example, we adjust the DP quality of Linux_For_Beginners.pdf to 300.

$ pdftoppm -png -rx 300 -ry 300 Linux_For_Beginners.pdf Linux_For_Beginners

To see all the choices available and supported in pdftoppm, run the commands:
