Free Social Media Preview
See how your link looks when shared.
What is the Social Media Preview?
When someone shares your link, a preview card decides whether anyone clicks — the image, the headline, the description. Miss the Open Graph tags and your link shows up as a bare URL or a random cropped image, killing the click-through you worked for.
This social media preview tool fetches any URL and shows you exactly how it will look when shared on Facebook, LinkedIn and X, built from the page's real tags.

What does this tool do?
You enter a URL and the tool fetches the page and reads its Open Graph and Twitter Card tags — image, title, description and site name.
It renders preview cards the way each platform would, and warns you when a key tag is missing so links don't fall back to something unflattering.

Built from the page's actual OG and Twitter tags.

Benefits
- It shows the real card before you post, not after.
- It catches a missing image that would flatten your card.
- It previews multiple platforms in one place.
- It helps you raise click-through with a strong card.
Tips
- Set og:title, og:description and og:image on every shareable page.
- Use an og:image around 1200×630 for the sharpest large card.
- Add twitter:card as summary_large_image for a bigger X preview.
- Keep social titles punchy — they're often truncated.
- Use an absolute https URL for og:image.
- After changing tags, re-scrape in each platform's sharing debugger to clear the cache.
- Twitter falls back to Open Graph, so OG tags cover both.
- Give each important page its own tailored image and copy.
