HTML & Open Graph Code Snippet
Open Graph Standards & Social Sharing Documentation
Why do major platforms recommend 1200 × 630 px for <meta property="og:image">?▼
The 1200 × 630 pixel dimension represents the golden 1.91:1 aspect ratio officially standardized by Facebook, LinkedIn, Twitter/X, and Discord. Delivering an image at this resolution ensures crisp, high-DPI (Retina) display on 4K monitors and mobile screens without pixelation or ungraceful stretching.
How does Twitter/X card fallback and summary_large_image work?▼
Twitter looks first for explicit <meta name="twitter:image"> tags. If absent, it seamlessly falls back to <meta property="og:image">. Setting twitter:card to summary_large_image renders a full-width visual card that achieves up to 3x higher click-through rates (CTR) compared to standard small square thumbnails.
Why do social crawlers cache previews, and how do you clear them?▼
To reduce network traffic, platforms like Facebook, Twitter, and LinkedIn cache Open Graph metadata and images on their edge servers for days or weeks. When you update an image, you must force-refresh the platform crawler cache using the official Facebook Sharing Debugger, LinkedIn Post Inspector, or by appending a cache-busting query parameter (e.g., ?v=2) to the image URL.
Privacy & Zero-Upload Client-Side Guarantee▼
All image parsing, metadata rendering, safe-zone bounding checks, and high-DPI mockup canvas rasterization occur 100% locally inside your web browser using HTML5 Canvas and native JavaScript FileReader/Blob APIs. No uploaded banners or draft descriptions are ever transmitted to external servers.
