What does the Open Graph Preview do?
Paste your page’s HTML source (or just its <head>) and click “Read tags” to extract og:title, og:description, og:image and Twitter tags — falling back to the <title> and meta description like social apps do. Or type values directly to experiment.
The tool shows Facebook/WhatsApp-style and X-style cards and lists problems such as a missing image or a long title. Browsers cannot fetch other websites’ HTML directly, which is why you paste it — this also keeps unpublished pages private.
How to use the Open Graph Preview
- Open your page, view its source (Ctrl+U) and copy it — or skip and type values.
- Paste the HTML and click “Read tags from HTML”.
- Review the card previews and warnings.
- Fix your tags with the Open Graph Generator if needed.
Examples
Missing image
A page with only a title tag shows a card with “No image” and a warning to add a 1200 × 630 og:image.
