Frequently Asked
Questions
Everything you need to know about social share preview.
Open Graph is a protocol Facebook introduced in 2010 that lets any web page control how it appears when shared on social media. You add <meta property='og:...'> tags to your page's <head>, and platforms like Facebook, LinkedIn, Discord, and Slack read them to build a preview card with title, description, and image. The protocol was extended by Twitter's 'Twitter Cards' and is now the de-facto standard for cross-platform link previews.
1200 × 630 pixels (1.91:1 aspect ratio) is the safe size for Facebook, LinkedIn, and Slack. X / Twitter uses 1200 × 675 (or 1200 × 600 for the smaller card). Discord and WhatsApp auto-crop, but starting with 1200 × 630 and using the central 1080 × 600 of the image for key content gives you the best results across all platforms. The maximum file size Facebook accepts is 8MB; the safe target is under 1MB for fast loading.
Each platform renders the og: tags slightly differently. Facebook shows the full card with image on top. X / Twitter truncates the description aggressively and sometimes shows a smaller card. LinkedIn shows a similar card but with a different font and domain label. Slack and Discord use the image prominently but truncate the description to one line. WhatsApp shows a tiny preview with just the title and domain. The only way to optimize for all is to keep your title under 60 chars and your description under 100 chars.
Each platform caches your preview image and metadata. Facebook uses a 'sharing debugger' at developers.facebook.com/tools/debug/ to force a re-scrape. X / Twitter has a 'Card Validator' at cards-dev.twitter.com/validator. LinkedIn uses a 'Post Inspector' at linkedin.com/post-inspector/. After updating your tags, run the URL through the platform's debug tool to clear the cache before sharing again. The cache is typically 7 days for Facebook, 7 days for X, 7 days for LinkedIn.
Yes on both. Completely free, no signup, no per-preview limit. 100% private — every preview renders in your browser. Your og: tags, image URLs, and page URLs are never sent to our servers, never logged, never used to train any AI. Open DevTools → Network while you use it: zero outbound requests carry your data. The only network activity is the og:image URL you provided, which the browser loads directly to render the preview — same as if you opened the URL in a new tab.
