About Open Graph & meta tag previewer
Meta tag previewer shows what a link will look like before you share it. It reads the tags that link previews are built from: the HTML title and meta description, Open Graph tags such as og:title, og:description, og:image and og:site_name, X card tags such as twitter:card, and the theme color Discord uses for its embed stripe. It then draws seven previews: a Google search result, Facebook and LinkedIn link posts, an X card in large-image or summary format, a Slack unfurl, a Discord embed and an iMessage-style bubble.
When a field is missing, the previews fall back the way most platforms do, for instance from og:title to the page title, and the source is noted in the warnings. The image is checked too: its pixel size and type are read from the file header, so you learn whether it is below Facebook's 200 × 200 minimum, too large for X's 5 MB limit, an unsupported SVG, or the wrong shape for a 2:1 large card.
The Write tags tab works without fetching anything and outputs a ready block of meta tags. Previews are approximations: platforms change their designs, cache cards for days, and some show different text to signed-in users. To refresh a card that was already shared, use the platform's own debugger after you publish.
Privacy
In Check a URL, the address goes to our server, which downloads that page once and the first bytes of its og:image to read the tags and the image size; nothing is stored or logged. The preview images then load in your browser directly from the site that hosts them. Write tags runs only in your browser.
