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