Enter a title, description and image URL, or paste <head> code, to preview the link as a search result, a large-image social card and a messenger card. Checks text length and the 1.91:1 image ratio, and writes the meta tags.
Paste the <head> of a page's source and the fields fill from og:title, og:description, og:image, og:site_name, og:url and canonical. This tool never fetches other sites for you.
Processed in your browser only. What you type is never uploaded. For the preview, only the image itself is loaded from its address.
Good to know. The previews imitate common link card layouts, so each service crops text and images a little differently. Services also cache link previews, so a fix may not show up right away.
No. It never fetches another site's HTML for you. Copy the <head> from the page source and paste it in to read the og tags. Only the image is loaded from its address for the preview.
1200 × 630px (1.91:1) is the most widely used. Other ratios get cropped in large cards, and images under 600px wide often show as a small thumbnail instead.
Around 60 characters for the title and 155 for the description are safe. Services cut by pixel width, so the exact limit varies.
Services cache link previews for a while. Use the service's preview refresh tool, or share the URL with something like ?v=2 added so it's read again.
