About Open Graph Previewer
The Open Graph Previewer fetches any public URL and instantly shows how the page will appear when shared on LinkedIn, Twitter/X, WhatsApp, Slack, Discord, and in Google search results — all in one view, with no browser extension or plugin required.
When you paste a link into a message, the platform reads Open Graph meta tags from the page’s HTML to build the preview card: the image, title, and description. If those tags are missing, misconfigured, or the wrong size, the preview looks broken or generic — a plain URL instead of a polished card. This tool makes it easy to see exactly what people see before you share.
The tag inspector table lists every relevant OG and Twitter Card tag found on the page, its current value, character count, and a pass/warn/fail status. The OG score summarises how completely the page is configured, with specific deductions for common problems like a missing og:image (the single most impactful tag for click-through rates) or a description that exceeds the recommended 155-character limit.
Checking OG tags is useful any time you publish or update a page that will be shared: blog posts, product pages, landing pages, portfolio work, press releases, or any content you want to look its best in a feed. It is also useful when debugging why a cached preview looks wrong — paste the URL, confirm the current live tags are correct, then use the platform’s own cache-busting tools to force a refresh.
Free, no signup required, works on any public URL.
Frequently asked questions
Open Graph tags are meta tags in a page's HTML that control how the page appears when shared on social networks. Tags like og:title, og:description, and og:image determine the preview card shown on LinkedIn, Facebook, Twitter, and messaging apps.
Each platform has its own rules for which tags it reads and how it sizes the preview. LinkedIn prefers a 1.91:1 image ratio, Twitter uses either a large card or a small summary card, and WhatsApp and Slack have their own compact formats. This tool shows you all six views at once.
The recommended size is 1200×630 pixels, which gives a 1.91:1 ratio. This renders well on LinkedIn, Facebook, and Twitter large card. Images that are too small or the wrong ratio get cropped or scaled unexpectedly.
Platforms cache OG data aggressively. If you recently added or changed og:image, the old (empty) version may still be cached. Use platform-specific debug tools like the LinkedIn Post Inspector or Twitter Card Validator to force a refresh. This previewer always fetches fresh data.
