Open Graph Preview
When you share a link on Facebook, LinkedIn, WhatsApp or Slack, the app reads Open Graph tags to build a card. Enter your values (or paste your page’s <head> HTML) to preview a generic card and catch missing images or overly long text before you publish.

Frequently asked questions
Does this fetch my live page?
No. Browsers block reading other sites’ HTML from a web page, and we do not use a server. Paste the HTML or type the values yourself. If you enter an image URL, your browser loads that image directly to display it.
What image size works best?
1200 × 630 pixels (about 1.91:1) is widely recommended. Keep important content away from the edges because some apps crop to a square.
Is this exactly what Facebook shows?
No. It is a neutral approximation. Each platform styles and truncates cards differently and changes them over time.
