Convert multi-page PDFs into a single vertical long image by concatenating all pages. Use when the user asks to convert PDF to long image, combine PDF pages into one image, or create a scrolling screenshot from a PDF document.

PDF to Long Image

Convert multi-page PDFs into a single vertical long image, useful for sharing documents as scrolling images or creating visual summaries.

Quick Start

# Basic usage
uv run python ~/.openclaw/skills/pdf-to-long-image/scripts/pdf_to_long_image.py input.pdf

# Specify output path
uv run python ~/.openclaw/skills/pdf-to-long-image/scripts/pdf_to_long_image.py input.pdf output.png

# Higher resolution
uv run python ~/.openclaw/skills/pdf-to-long-image/scripts/pdf_to_long_image.py input.pdf output.png --scale 3

How It Works

  1. Opens the PDF using pymupdf (fitz)
  2. Renders each page at the specified scale (default 2x for clarity)
  3. Vertically concatenates all pages into a single image
  4. Saves as optimized PNG

Options

Option Default Description
input (required) Path to the PDF file
output input_long.png Output image path
--scale 2.0 Render scale factor (higher = more detail)

Dependencies

The script requires these packages (install with uv):

uv pip install pymupdf pillow

Example Output

Converting 32 pages from document.pdf...
  Page 1/32: 1684x1190
  Page 2/32: 1684x1190
