Free Social Card Preview Tool: See How Your Link Looks When Shared

Use 1200×630 pixels (a 1.91:1 ratio). This size is great on X (Twitter), Facebook, LinkedIn and Slack, but keep your text and logo away from the edge, since platforms often crop images.

Add og:title, og:description, og:image and og:url for most platforms. For X (Twitter), also add twitter:card (set to summary_large_image), twitter:title, twitter:description and twitter:image.

Social platforms will save (cache) the first version of your link. Once you've changed your Open Graph or Twitter tags, you need to re-scrape the URL with the X Card Validator, Facebook Sharing Debugger or LinkedIn Post Inspector to refresh the card.

Yes, this free link preview tool runs in your browser and doesn't need any sign-up. You simply enter your page's URL and preview your title, description and image.

Add an og:image tag with the full https URL to a public 1200×630 JPG or PNG image, and add og:image:alt (a description of the image). Then re-scrape your link on X, Facebook or LinkedIn to see the changes.

Keep your Open Graph title to about 70 characters and your description to about 200 characters to prevent it from being cut off.
