lovstudio pdf2png — PDF to Vertically Concatenated PNG
Convert multi-page PDF files into a single tall PNG image. All pages are rendered at 2x scale (Retina quality) and stitched vertically. Uses macOS CoreGraphics directly — no pdftoppm, no ImageMagick, no Ghostscript.
When to Use
- User wants to convert a PDF to a single PNG image
- User needs a long screenshot-style image of a PDF
- User wants to share PDF content as an image (WeChat, social media, etc.)
Workflow
Step 1: Identify PDF files
Locate the PDF file(s) the user wants to convert. If multiple PDFs or output
location choices are ambiguous, use AskUserQuestion to confirm the path(s)
before running conversion.
Step 2: Execute
bash sgc-pdf2png/scripts/pdf2png.sh /path/to/file.pdf
Output: /path/to/file.png (same directory, same name, .png extension).
For multiple files:
bash sgc-pdf2png/scripts/pdf2png.sh file1.pdf file2.pdf file3.pdf
Step 3: Verify
Check the output file exists and report its size.
