PreviewChecks

PreviewChecks is a free tool for testing link previews before you publish or share a URL. It shows how your page appears across Open Graph, X cards, Pinterest and chat apps, then highlights missing images, weak titles, broken descriptions, wrong thumbnails and metadata issues. Unlike basic meta tag checkers, it focuses on the real previews people see when links are shared. Use it before launches, blog posts, landing pages and campaigns to avoid broken previews and make every shared link look polished.
