How it works

        

        

            

                Values you type are turned into og:* and twitter:* tags and rendered
                into a card preview using the same rules the major platforms use: a large image card near
                1.91:1, or a compact square summary card. Length and URL checks flag the issues
                that most often make a shared link look broken. Nothing is uploaded or requested — the
                page works fully offline once loaded.
