Frequently asked questions
Is the social share preview checker free?
Yes. You can run up to 20 checks a day with no account, and up to 60 a day when you sign in with Google. No credit card required.
Why does my link show no image on WhatsApp or Facebook?
Usually a missing og:image tag, an image that fails to load, or one that is too small or too heavy. Paste your URL above and the checker will tell you which one it is.
What size should my og:image be?
1200x630 pixels (a 1.91:1 ratio) works everywhere: Facebook, X, LinkedIn, WhatsApp, and Discord. Below 600px wide, most platforms fall back to a tiny thumbnail.
Twitter's Card Validator is gone. Does this replace it?
Yes. X retired its validator's preview in 2022. This tool renders the X card from your twitter:card and og tags, the same fallback chain X itself uses.
Is the preview pixel-perfect?
It is a close approximation built from your real tags. Platforms restyle their cards constantly, so treat it as a reliable guide to what will show and what is broken.
