Social share preview checker
Paste a link and see the card people get on LinkedIn, X, WhatsApp, Slack and iMessage before you post. We read the tags each app reads and flag what's missing or cut off.
Tips
- Use 1200×627. Smaller images show as a thumbnail on LinkedIn and X.
- Keep titles under 70 characters. Longer titles get cut mid-word in most apps.
- Changed your image? Apps cache previews. Share the link with ?v=2 on the end to force a fresh card.
Questions
Why does my link show no image on LinkedIn?
The page has no og:image tag, the image is too small (under 1200×627 shows as a thumbnail), or LinkedIn cached an old version. Fix the tag, then re-share with ?v=2 on the end of the link.
How do I refresh a cached preview?
Apps cache previews for days. LinkedIn has a Post Inspector; for WhatsApp and Slack, share the link with a harmless query like ?v=2 so it's treated as new.
Are these real screenshots?
They're faithful look-alikes built from the tags apps read. Each app crops a little differently, so leave a margin around important text in your image.
