Convert PDF files to JPEG images with pdftoppm, support optional page ranges, and bundle generated JPGs into a zip archive for sharing. Use when a user wants to turn a PDF into page images, extract selected pages, or package the results. Requires poppler-utils / pdftoppm.

pdf2jpg

Overview

Convert a PDF into JPEG page images using pdftoppm from poppler-utils, then optionally zip the generated JPGs.

Requirements

  • pdftoppm must be available in PATH
  • Install the poppler-utils package before running the scripts

Install poppler-utils

  • Debian / Ubuntu:

    sudo apt update
sudo apt install -y poppler-utils

  • Windows:

    • Install Poppler via a package manager, then make pdftoppm.exe available in your PATH
    • Common options:
      • winget install -e --id oschwartz10612.Poppler
      • choco install poppler
      • scoop install poppler

  • macOS:

    brew install poppler

Standard workflow

  1. Convert the PDF with scripts/pdf2jpg.sh
  2. Bundle the output images with scripts/zip_jpgs.sh if needed
./scripts/pdf2jpg.sh input.pdf
./scripts/pdf2jpg.sh input.pdf 2 5
./scripts/zip_jpgs.sh input.pdf
./scripts/zip_jpgs.sh input.pdf /tmp/output.zip

Scripts

scripts/pdf2jpg.sh

  • Prompts for the PDF path if none is supplied
  • Verifies the input file exists
  • Verifies pdftoppm is installed and prints a poppler-utils install hint if not
  • Writes JPEGs beside the PDF using the PDF basename as the output prefix
  • Accepts optional first and last page arguments

scripts/zip_jpgs.sh

  • Finds matching basename-*.jpg files for the PDF
  • Creates a zip archive containing those JPGs
  • Uses ${base}-jpgs.zip by default when no output path is supplied

Notes

  • Output files follow the pdftoppm naming convention, typically basename-1.jpg, basename-2.jpg, etc.
  • If you need different image quality, output naming, or archive behavior, edit the bundled scripts rather than reimplementing the command inline.
