Preview How Your Links Look on Social Media
When someone shares your page on Facebook, X, LinkedIn, or Discord, the preview card they see is controlled by your Open Graph and Twitter meta tags. Get them wrong and your link shows up as a bare, unclickable text snippet with no image — a real drop in engagement. This validator fetches any URL, reads its social tags, and renders pixel-accurate previews of how the link will actually appear on each major platform, so you can fix problems before you publish.
Because each platform sizes and styles its cards differently, the tool shows separate previews for Facebook, X/Twitter, LinkedIn, and Discord. You see the real title, description, image, and domain exactly as your audience will — no more guessing or repeatedly re-sharing a test link.
Catch Missing Tags and Sizing Problems
Beyond the visual preview, the validator runs a full checklist and gives you a clear pass, warning, or fail for each item: is there a title and description, is an og:image present, is it large enough for a big card, is twitter:card set, and is og:url declared? Each result comes with a plain-English explanation and the recommended fix.
It reads both Open Graph and Twitter Card tags, resolves relative image paths to absolute URLs, and falls back to the page title and meta description when social tags are missing — mirroring how platforms actually behave. Whether you are a marketer polishing a campaign, a developer shipping a new page, or an SEO auditing a site, this is the fastest way to make sure every shared link looks its best.

Frequently Asked Questions
Open Graph (OG) tags are meta tags in a page's HTML that control how the page looks when shared on social media — the title, description, and image that appear in the preview card on Facebook, LinkedIn, Discord, and more. Twitter/X uses its own similar set of twitter: tags.
Common causes are a missing og:image, an image that is too small or the wrong aspect ratio, a missing og:title or description, or the platform caching an old version. This validator checks all of these and shows you exactly what each platform will display, so you can spot the problem.
For a large, eye-catching card, use an image of at least 1200×630 pixels (a 1.91:1 ratio) and set og:image:width and og:image:height. This works well across Facebook, LinkedIn, and X's "summary_large_image" card. Smaller images may render as a tiny thumbnail or be ignored.
Yes. The tool reads both Open Graph and Twitter Card tags, shows a dedicated X/Twitter preview, and warns if twitter:card is missing. X falls back to Open Graph tags when Twitter-specific ones are absent, and the preview reflects that.
No. The tool fetches only the page head to read its meta tags through a secure server endpoint and stores nothing. The preview images are loaded directly from the target site in your browser.
