# PDF to PNG — OpenClaw Plugin
Convert PDF pages to PNG, JPG, or WebP images using the [PDFAPIHub](https://pdfapihub.com) API. This OpenClaw plugin renders PDF pages as images with full control over DPI, dimensions, and format — plus quick presets for thumbnails and social media previews.
## What It Does
Render any PDF page as an image — perfect for thumbnails, social previews, print-ready exports, and document previews without embedding a PDF viewer.
### Features

- **Page Selection** — Convert specific pages or ranges (e.g. `1-5`, `1,3,5`)
- **Resize** — Set custom width/height for thumbnails or social media
- **Background Color** — Fill transparent PDF backgrounds with any hex color
- **Thumbnail Preset** — One-command first-page thumbnail at 200px
- **OG Image Preset** — One-command 1200x630 social media preview
- **Image to PDF** — Reverse: combine images into a PDF with page layout
- **Page Size Control** — A4, Letter, original for image-to-PDF
