LinkedIn Post → Image Tool (Local Use)

This is a small local tool that converts LinkedIn embedded posts into downloadable images.

It loads a LinkedIn embed, renders it in a headless browser using Puppeteer, and saves a high-quality PNG screenshot.

Useful when you want to reuse LinkedIn posts as images for other platforms.

Notes

• The tool runs locally using Express + Puppeteer.
• A backend screenshot is required because browsers cannot capture cross-origin iframes like LinkedIn embeds.
