Open Graph tags control how your page appears when shared on Facebook, LinkedIn, Slack, and most other social platforms — get them wrong, and your shared link can show a blank image or a confusing snippet.
This tool previews your Open Graph title, description, and image as a social share card, with warnings if your text is likely to be cut off.
How it works
Enter your page's og:title, og:description, og:image URL, and page URL. The tool renders a preview of how the share card will typically look, and flags text that exceeds common display length guidelines.
- Enter your Open Graph title, description, image URL, and page URL.
- Click Preview Card.
- Check the length warnings and the live social card preview.
Examples
Previewing a blog post share
Entering a blog post's title, description, and featured image URL shows exactly how the link will look when someone shares it on Facebook or LinkedIn.
Who should use it
- Checking how a new blog post or landing page will look before sharing it on social media.
- Debugging a share card that looks wrong or shows the wrong image.
Industry applications
- Content marketing and social media management
- SEO and web development
Advantages
- Shows a live visual preview of the share card, not just character counts.
- Flags title and description length against widely used platform guidelines.
Limitations
- Cannot perfectly replicate every platform's exact rendering, since each one differs slightly.
Common mistakes to avoid
- Using a very long title or description that gets cut off awkwardly mid-sentence on most platforms.
- Forgetting to set an og:image, resulting in a plain, unappealing share card.
Best practices
- Keep your og:title and og:description concise and compelling — they function like a headline and subhead for your shared link, not just a copy of your page's meta tags.
Tips
- Always test your actual page's share preview using each platform's own debugging tool (like Facebook's Sharing Debugger) in addition to this generator, since platforms cache Open Graph data and may show stale previews.
