How can I convert all PDF files in a folder to JPG or PNG format using pdftoppm on Ubuntu?

I’ve been trying to figure out a way to convert all the PDF files in a specific folder to JPG or PNG format using pdftoppm on my Ubuntu system, but I keep hitting a wall. I’ve read a bit about pdftoppm and it seems like it should be a good tool for this, but I’m not quite sure how to make it work effectively for batch conversions.

I have a folder packed with several PDFs that I need to go through for a project. The PDFs are a mix of educational materials and some old reports that I want to archive as images. I know I could convert them one by one using some command line magic, but honestly, that sounds way too tedious. I really just want to run a command or a script that takes care of everything at once, you know?

I found a couple of tutorials online, but they were either too basic or didn’t quite cover what I needed to do. I keep getting stuck on the command syntax or figuring out how to make it loop through all the files without having to type everything out for each one. At one point, I thought about writing a small shell script, but I’m a bit rusty with that sort of thing.

So, what I have in mind is something like this: I want to point pdftoppm at my folder, have it convert all the PDFs to JPG or PNG in a single command, and ideally, all the images should be saved in the same folder or a new one I specify. I’ve seen hints about wildcard characters or maybe using `*.pdf` to select all files, but I can’t seem to get the exact command structure right.

If anyone has a simple solution or a set of commands that would do the trick, I’d really appreciate the help! If possible, could you explain it like you’re talking to someone who’s a little confused? Thanks a ton!

    1. PDF to JPG/PNG Conversion Help


      Convert PDF to JPG/PNG using pdftoppm

      Alright, let’s tackle this together! You’re on the right track thinking about using pdftoppm for batch converting your PDFs to images. Here’s how you can do it:

      Step-by-Step Guide

      1. First, open a terminal. You can usually find it by searching for “Terminal” in your applications menu.
      2. Navigate to the folder that contains your PDF files. You can do this using the cd command. For example:

        cd /path/to/your/pdf/folder
      3. Now, you can run the command to convert all PDF files in that folder. If you want to convert them to JPG, use:

        pdftoppm -jpeg *.pdf output

        This command will create JPG images. The images will be named output-1.jpg, output-2.jpg, and so on, for every page in your PDFs. If you want PNG format, simply replace -jpeg with -png:

        pdftoppm -png *.pdf output
      4. If you want these images saved in a different directory, you might want to create a folder first:

        mkdir ../output_images

        Then modify your command slightly:

        pdftoppm -jpeg *.pdf ../output_images/output

      A Quick Breakdown of the Command

      • pdftoppm: The tool you’re using to convert PDFs.
      • -jpeg or -png: This tells pdftoppm the format to convert to.
      • *.pdf: This is the wildcard that tells it to look for all PDF files in the folder.
      • output: This is what you want to name the output files, and pdftoppm will append the page numbers to it.

      Notes

      Remember to ensure that pdftoppm is installed on your Ubuntu. You can install it if it’s not already there by running:

      sudo apt-get install poppler-utils

      That’s it! Just tweak the paths and names to fit your needs, and you should be good to go! This should save you plenty of time compared to doing it one at a time. Good luck! 🚀



    2. To convert multiple PDF files in a folder to JPG or PNG format using pdftoppm, you can create a simple shell script that automates the process. Open your terminal and use a text editor, like nano or vim, to create a new script file. For example, you can create a script called `convert_pdfs.sh` with the command: nano convert_pdfs.sh. Inside this file, you can write the following lines:

      #!/bin/bash
for file in /path/to/your/folder/*.pdf; do
    pdftoppm "$file" "${file%.pdf}" -jpeg
done

      This script uses a for loop to iterate over each PDF file in the specified folder (`/path/to/your/folder/*.pdf`). The command pdftoppm takes each PDF file and converts it into JPEG format. The output image files will be named the same as the original PDF files, just with the addition of the “.jpg” extension. If you prefer PNG format, simply replace -jpeg with -png. After saving the script, make it executable by running chmod +x convert_pdfs.sh. Finally, execute it with ./convert_pdfs.sh. This will convert all the PDF files in that folder into images without you having to type commands for each individual file.
