SVG to Image

Convert SVG files to PNG or JPG. Useful when you have vector graphics (e.g. from map-grabber, diagrams, or design tools) and need a raster image to send in chat or use in documents.

Dependencies

  • cairosvg (SVG rendering)
  • Pillow (only for JPG output)

Setup: OpenClaw does not install Python packages automatically. After installing this skill, run once: pip install -r requirements.txt (from the skill folder). On Linux (e.g. Ubuntu/Debian), install the Cairo library first: sudo apt install libcairo2. If a script fails with ModuleNotFoundError or a cairo library error, install the missing package or system library.

Usage

Convert SVG to PNG or JPG

Parameters:

  • input: Path to the SVG file.
  • -o, --output: Output file path (default: same name as input with .png or .jpg).
  • -f, --format: png (default) or jpg.
  • --width, --height: Optional output size in pixels (keeps aspect ratio if only one is set).
  • --dpi: Scale for rasterization (default 96).
# SVG to PNG (default)
python3 scripts/convert_svg.py drawing.svg -o drawing.png

# SVG to JPG
python3 scripts/convert_svg.py drawing.svg -f jpg -o drawing.jpg

# Fixed width 800px (height auto)
python3 scripts/convert_svg.py map.svg -o map.png --width 800

Sending images to Telegram

Used from the OpenClaw Telegram conversation. Run the script with -o <path>.png or -o <path>.jpg, then send that file to the user via the OpenClaw message/media tool.

OpenClaw allowed paths: The message tool only sends files from allowed dirs (~/.openclaw/media/, ~/.openclaw/agents/, or /tmp). Use e.g. -o ~/.openclaw/media/out.png or -o /tmp/out.png; do not use the skill install directory or sending will fail.

Agent behavior: When the user asks to convert an SVG to PNG or JPG (or "send as image"), run the script directly with exec: use convert_svg.py <svg_path> -o <output>.png (or -f jpg) with output path under an allowed dir, then send the generated image. Do not ask for confirmation; execute and return the image.

Examples

User: "Convert this SVG to PNG so I can send it in Telegram."
Action: Run convert_svg.py <path> -o /tmp/out.png, then send the PNG to the user.

User: "Turn map.svg into a JPG, 1200px wide."
Action: Run with -f jpg -o /tmp/map.jpg --width 1200, then send the JPG.
