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.

Check it yourself: open your browser’s developer tools, select the Network tab and use the tool. Your file never appears in an upload request.

Ads and anonymous visit statistics, when enabled, make their own requests, but they never receive your files or text.
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.
