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 lovstudio-pdf2png/scripts/pdf2png.sh /path/to/file.pdf

Output: /path/to/file.png (same directory, same name, .png extension).

For multiple files:

bash lovstudio-pdf2png/scripts/pdf2png.sh file1.pdf file2.pdf file3.pdf

Step 3: Verify

Check the output file exists and report its size.

CLI Reference

Output is always <input>.png in the same directory as the input file.

Finder Quick Action

This skill can also be installed as a macOS Finder Quick Action for right-click conversion. See lovstudio/mac-pdf2png for the Automator workflow.
