You can also use the “convert” command to convert PDF to image in the Linux system. We have to use the -rx and -ry command for that.įor the file we have used previously, the syntax is going to be: pdftoppm -jpeg -rx 300 -ry 300 Sample.pdf images_extracted_from_sample_pdf

Let us say we want to set the X resolution to be 300 and the Y resolution to be 350 also. To change that, we need to set the resolution of both of the axes individually. The pdftoppm command assumes the DPI value to be 150 by default. How to control that? Look at the syntax closely. Sometimes we need to control the DPI value of an image.

Usually, when the DPI value increases, the picture quality also increases but takes a large space to exist and vice versa. Customized Quality for the Converted Image FileĮach image we see has a DPI (Dots Per Inch) value related to that image. Only one image file will be created here. If we want to convert the fifth page to be converted, we have to write: pdftoppm -jpeg -f 5 -l 5 Sample.pdf images_extracted_from_sample_pdf Here x represents the page number we want to convert into PDF. This time, the starting and finishing page number is going to have the same numerical value. The syntax to convert a single page is the same. Converting a Single Page From a PDF to ImageĪctually, it is a derivative of the last procedure we have seen. The output name will be like this: images_extracted_from_sample_pdf-9.jpeg, and it will count up to 12. Writing the short form will cause errors here. The image type can be anything like png or any type of extension. So, how do we convert that whole PDF into images? Just write in the terminal: pdftoppm -jpeg Sample.pdf images_extracted_from_sample_pdf The ideal syntax to do so is as follows: pdftoppm convert pub to pdf linux

Each of them is going to be discussed below. We can convert a PDF file in various ways. Once you have poppler installed, for any Linux distro, that can be Ubuntu or Debian-based or Arch Linux, the rest of the syntax is the same for each of them.
