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.
Set the og:title, og:description, and og:image meta tags in your page's head. This tool designs the image at the standard 1200x630 size, previews the card as each platform renders it, and hands you the exact tags to paste.
1200 by 630 pixels is the standard that renders well everywhere. The designer works at exactly that size, so nothing critical gets cropped by a platform's aspect ratio.
Either the og tags are missing or the platform cached an old scrape. Add correct tags (this tool generates them), then use the platform's sharing debugger to refresh the cache.
Adding twitter:card and its siblings alongside the og tags guarantees X renders the large summary card. The generated snippet includes both sets, ready to paste.
Yes: live mockups show your card as Twitter/X, Facebook, and LinkedIn will draw it, so the first impression is checked before the link goes anywhere.
