What is the difference between Open Graph and Twitter Cards?

Open Graph (og:) tags power previews on Facebook, LinkedIn, Slack and most platforms. Twitter/X uses its own twitter: tags but falls back to og: tags. This tool emits both so previews look right everywhere.

What image size should I use?

Use a 1200x630 pixel image (1.91:1 ratio) for the large summary_large_image card. Keep it under 5MB and use an absolute https URL, because crawlers cannot resolve relative paths.

Do I need og:url to be absolute?

Yes. og:url and og:image must be full absolute URLs including the scheme. Relative URLs are ignored by Facebook and Twitter crawlers and will break the preview.

Why is my preview not updating?

Platforms cache scraped metadata. After changing tags, re-scrape with Facebook's Sharing Debugger or post a fresh link, since old previews can persist for hours or days.

Are article tags required?

No, they are optional enrichments. For og:type article you can add article:published_time and article:author, which some platforms display, but the core og: tags are enough for a valid preview.

Open Graph Meta Tags Generator

Rich link previews in one paste

The Open Graph Meta Tags Generator produces the og: and twitter: meta tags that control how your page looks when shared. Without them, social platforms guess at a title and image — often badly. Fill in a few fields and copy a complete, valid block of head markup that renders a proper share card on Facebook, LinkedIn, Slack and Twitter/X.

How it works

Open Graph is a small vocabulary of <meta property="og:..."> tags read by crawlers when a link is shared. The four essentials are og:title, og:description, og:image and og:url, plus an og:type that classifies the page. Twitter layers its own tags on top:

<meta property="og:type" content="article" />
<meta property="og:title" content="My Page Title" />
<meta property="og:image" content="https://example.com/cover.png" />
<meta name="twitter:card" content="summary_large_image" />

Choosing a page type switches og:type (website, article, product, profile) and reveals type-specific extras such as article:published_time. Image and URL fields must be absolute https URLs or crawlers ignore them.

Tips and notes

Size your og:image at 1200x630 for the large card format.
Keep titles under ~60 characters and descriptions under ~155 so they are not truncated.
After editing tags, re-scrape with Facebook’s Sharing Debugger to clear the cached preview.
