How Open Graph previews work and why they matter for social media engagement

This Open Graph preview tool fetches any URL from our server and renders simulated previews of how the page will appear when shared on Facebook/LinkedIn, Twitter, and Slack. It reads the live og:title, og:description, og:image, og:type, and Twitter Card tags and renders them exactly as each platform would display them. Including the domain attribution, image aspect ratio, and text truncation rules.

When someone shares your link on social media, the platform reads your OG tags to build the preview card. A missing og:image means no image shows up. Just a text-only card with much lower engagement. An incorrect image size means cropping or distortion. A missing og:title means the platform guesses a title from your page content. Getting OG tags right can double or triple click-through rates from social shares.

FAQ

Frequently asked questions about Open Graph tags and social media previews

What are Open Graph tags?
Open Graph (OG) tags are HTML meta tags in the <head> of a webpage that control how the page appears when shared on social media. They were created by Facebook and are now supported by LinkedIn, Twitter, Slack, Discord, WhatsApp, and most other platforms. The key tags are og:title (the headline), og:description (the summary), og:image (the preview image), and og:type (article, website, etc.). Without OG tags, social platforms scrape whatever content they find. Often resulting in ugly, irrelevant previews.
What image size should I use for og:image?
The recommended og:image size is 1200×630 pixels (1.91:1 aspect ratio). This renders well on Facebook, LinkedIn, Twitter, and most other platforms. The minimum size is 200×200 pixels, but small images are shown as tiny thumbnails. For Twitter cards specifically, summary_large_image requires at least 300×157 pixels. Use JPEG or PNG format, keep file size under 8MB, and use an absolute URL (https://) in the og:image tag.
What is a Twitter Card?
Twitter Cards are Twitter's equivalent of Open Graph tags. They control how your content appears when shared on Twitter/X. The main card types are: summary (small square image + text), summary_large_image (large banner image), app (for mobile apps), and player (for video/audio). Twitter reads og: tags as fallbacks if twitter: tags aren't present, so setting og: tags first covers both platforms. This tool shows both the Twitter Card preview and the Open Graph preview.
Why is my OG image not updating after I changed it?
Social platforms cache OG data aggressively. Facebook/LinkedIn cache for up to 7 days. To force a refresh: Facebook. Use the Sharing Debugger (developers.facebook.com/tools/debug) and click 'Scrape Again'. LinkedIn. Use the LinkedIn Post Inspector (linkedin.com/post-inspector). Twitter. The Twitter Card Validator tool. After refreshing, the platforms re-fetch and cache the new data. This tool shows the live current state of your OG tags, not the cached version that social platforms may be serving.
