About this tool

Paste raw HTML or fetch a URL — the tool extracts the OpenGraph, Twitter Card and classic <meta> tags, then renders a mocked-up share-card preview for seven platforms side-by-side (Facebook, Twitter summary, Twitter summary_large_image, LinkedIn, Slack unfurl, Discord embed, iMessage). Pure CSS mockups — no live screenshot.
