# 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
bash lov-pdf2png/scripts/pdf2png.sh /path/to/file.pdf
```
Output: `/path/to/file.png` (same directory, same name, `.png` extension).
For multiple files:
```bash
bash lov-pdf2png/scripts/pdf2png.sh file1.pdf file2.pdf file3.pdf
```
### Step 3: Verify
Check the output file exists and report its size.
## CLI Reference
| Argument | Description |
|----------|-------------|
| `file1.pdf [file2.pdf ...]` | One or more PDF files to convert |
Output is always `<input>.png` in the same directory as the input file.

+
+ 运行前读取本 Skill 包的 `skill.yaml`，由宿主提供 `skill-runtime/v1` 上下文。字段解析顺序为：当前请求、项目上下文、个人 Preferences、品牌 Profile、通用默认值。
