Social Share Card Previewer
Preview how a shared link will look on Twitter/X, Facebook, LinkedIn and Discord, and generate the matching Open Graph / Twitter Card meta tags.
About this tool
When you paste a link into X, Facebook, LinkedIn, Discord, WhatsApp or Slack, the site fetches your page and reads its Open Graph (og:*) and Twitter Card (twitter:*) tags to build the preview. Fill in the fields to see close approximations of each platform's card and get the tags to paste into your page's <head>, including the image size and alt text and a canonical link.
The image and page addresses must be full https:// URLs, because each platform fetches them from its own servers; the tool only loads images from full addresses, and you can preview an image from your device before uploading it. Use an image of 1200 × 630 px (a 1.91:1 ratio) so nothing important is cropped. Platforms cache previews, so after changing your tags use each one's debugging tool (such as Facebook's Sharing Debugger or LinkedIn's Post Inspector) to refresh it. Card designs change from time to time, so treat the previews as a close guide rather than pixel-perfect copies.
