Link Preview is a web infrastructure technique that fetches and parses Open Graph metadata, title, description, and thumbnail from a target URL to generate a rich card preview for display in social feeds, chat applications, or note-taking tools. APIs and Python libraries such as linkpreview and URLMeta automate this extraction, enabling knowledge graphs and collaborative platforms to surface contextual summaries alongside raw hyperlinks.
