Design the image and preview card that appear when your link is shared on social media. Build a perfect 1200×630 Open Graph image, see how it looks on X, Facebook, and LinkedIn, and copy the meta tags. All in your browser.
When you paste a link into a tweet, a LinkedIn post, a Slack message, or an iMessage, the big image-and-title card that pops up isn't magic — it's pulled from Open Graph meta tags in your page's HTML. Get them right and your links look professional and get more clicks; leave them out and you get a sad, blank rectangle. This tool builds both halves: a polished 1200×630 share image and the exact tags to make it show up.
It runs entirely in your browser. Your headline, artwork, and any uploaded image are composited on a local canvas and never sent to a server.
og: and twitter: tags for your page's <head>.og:image, and you're done.A link with a strong preview card stands out in a crowded feed and clearly signals what's on the other side — which means more clicks and more trust. The 1200×630 dimension is the sweet spot that renders crisply as a large summary card across every major platform.
No account, no upload, no watermark — design it, download it, paste the tags.
