Frequently Asked Questions
What is OpenGraph?
OpenGraph is a protocol created by Facebook that allows web pages to control how they appear when shared on social media. By adding og:title, og:description, and og:image meta tags to your HTML, you control the title, description, and image shown in link previews across Facebook, Twitter/X, Slack, Discord, LinkedIn, WhatsApp, iMessage, and more.
What are Twitter Cards?
Twitter Cards are Twitter/X's version of link previews. They use twitter:card, twitter:title, twitter:description, and twitter:image meta tags. The two main types are summary (small image) and summary_large_image (large image). Twitter falls back to OpenGraph tags if Twitter-specific tags are missing.
What is the recommended OG image size?
1200×630 pixels (1.91:1), PNG or JPEG, under 5MB. X crops the large card to 2:1 from the centre, Facebook and LinkedIn use about 1.91:1, and chat apps sometimes cut a square, so keep the message in the middle and 60px or more from every edge. SVG and AVIF pictures are not shown by X, Facebook or LinkedIn. The Image tab shades what each platform crops.
Why does X show a plain link instead of my preview?
Usually one of: no twitter:card tag (X then shows the small layout), a player card (X only draws it for approved domains), robots.txt blocking Twitterbot or the picture, a picture over 5MB or in an unsupported format, a page that answers Twitterbot slowly or differently than a browser, or a cached failure: X keeps a link's preview for about a week, and there is no longer a validator to clear it, so add something like ?v=2 to the link you post. Choose X under “Look at it as” and the Checks tab names the cause.
Which meta tags should every page have?
At minimum, every page should include: og:title, og:description, og:image, og:url, og:type, plus twitter:card for Twitter/X. Also include a standard <title> tag and meta description for search engines.
Is this tool free?
Yes, the Viewert OpenGraph Previewer is completely free. No account, no sign-up, no limits. Just paste a URL and preview your link instantly.
How does this tool work?
When you enter a URL, our server fetches the page (just like Google, Facebook, or Slack would), extracts all meta tags from the HTML, and renders platform-accurate previews. We don't store your URLs or any fetched content. The tool includes SSRF protection and only fetches public HTTP/HTTPS URLs.
