Open Graph Preview
Paste a URL — see exactly how it previews on Twitter/X, LinkedIn, Slack, and Facebook. Catches the most common cause of broken social shares: a missing or malformed og:image.
Frequently asked questions
Why don't all platforms show the same preview?
Each platform reads a different combination of tags. Twitter prefers twitter:* tags but falls back to og:*. LinkedIn reads only og:*. Slack uses both plus oEmbed. Facebook uses og:* exclusively. A URL can look great on one platform and broken on another.
What size should my og:image be?
1200×630 pixels (1.91:1 aspect ratio). This is the size that works across every platform. Anything smaller gets upscaled (blurry). Anything wildly different may be cropped or rejected.
Why is my og:image showing the old version after I updated it?
Facebook and LinkedIn cache OG images aggressively. Update by submitting your URL to https://developers.facebook.com/tools/debug/ and https://www.linkedin.com/post-inspector/ to force a re-scrape.
Do I need both og:title and twitter:title?
Strictly no — Twitter falls back to og:title. But if you want different copy per platform (longer for LinkedIn, punchier for Twitter), setting both lets you control each separately. Most sites just set og:* and let everything cascade.
