Open Graph Preview
Private by design — runs entirely in your browser
See exactly what a social-share card will look like before you publish. Type title, description, image and URL and the preview updates instantly.
Why doesn’t it fetch the URL automatically
Cross-origin fetches are blocked by browsers for most domains, so a one-click fetch would only work for sites that explicitly allow it. The tool keeps things deterministic by letting you paste the four fields you would otherwise extract from the page.
Will Facebook and LinkedIn show this exact card
Layout differs slightly per platform but the four fields drive every social card today. Facebook’s sharing debugger and LinkedIn’s post inspector reuse the same Open Graph values.
What image size works best
1200×630 pixels, less than 1 MB, JPG or PNG. The tool renders a 1.91:1 aspect ratio crop that matches what most platforms display.
