Open Graph Checker & Preview
Enter a URL to check its Open Graph and Twitter Card tags, or fill in the fields yourself. Either way you see the exact link card Facebook, X/Twitter, LinkedIn, and Slack will render, plus copy-ready meta tags to fix what's missing.

Why Open Graph tags matter
When someone shares your URL, social platforms read your Open Graph (og:) and Twitter Card meta tags to build the link card — the title, description, and image people actually see. Without them, your link shows up bare or with whatever the platform guesses, tanking click-through.
Preview before you ship
Fill in your title, description, image URL, and site name, and the tool renders the link card the way major platforms display it. Catch a truncated title or a wrong-aspect-ratio image before it's live, not after it's been shared a hundred times.
Copy-paste meta tags
The tool outputs a complete, correctly-named set of og: and twitter: meta tags ready to drop into your page's head. Use a 1200×630 image for the cleanest card across platforms.
Frequently asked questions
An Open Graph image of 1200×630 pixels, a 1.91:1 ratio, is the safe default. That size renders cleanly as a large card on Facebook, LinkedIn, and Slack, and as a summary image on X/Twitter.
X/Twitter falls back to Open Graph tags, but adding twitter:card and twitter:image gives you explicit control over how the card renders. This tool generates both sets for you.
Social platforms cache scraped metadata, so an old image can linger. After updating your tags, run the platform's debugger, such as Facebook's Sharing Debugger, to force a re-scrape.
Open Graph tags go in the head of your HTML document, alongside your other meta tags.
X retired its Card Validator's preview in 2022, so the practical check is a tool like this one: enter your URL, confirm twitter:card and twitter:image resolve, and review the rendered card. Posting the link in a private test post is the final confirmation.
Enter any public URL in the checker above and the tool fetches the page and lists every og: and twitter: tag it finds, flagging missing or malformed ones. Viewing source works too, but the checker also renders the resulting card so you see what a share would look like.
