See your link before you share it
Paste a URL. We read its tags and rebuild the card Google, X, Facebook, and WhatsApp will each show — then tell you what is missing. A 404ing og:image looks fine in your HTML and terrible in a group chat.
One page fetch and a partial read of the image it points at. Nothing is stored.
Questions people actually ask
Why does my link show no image on WhatsApp but works on Facebook?
WhatsApp drops the thumbnail on images over roughly 300 KB, and it will not resolve a relative og:image path. Facebook is more forgiving on both counts, so the same tags can render on one and not the other.
Why is my share card showing the old title after I fixed the tags?
Every network caches what it scraped. Re-share after clearing the cache in Facebook’s Sharing Debugger or by requesting the URL again with a cache-busting query string.
What size should an og:image be?
1200×630 pixels, under 300 KB, served over HTTPS at an absolute URL. That size earns the full-width card everywhere and stays inside WhatsApp’s thumbnail ceiling.
Does this change anything on my site?
No. We request the page once, read its tags, and request the first few kilobytes of the image it points at. Nothing is stored and nothing is published.
