Paste page source — or fetch a live URL — and confirm the exact tags Facebook, X, LinkedIn and messengers use for link previews.
🔒 Privacy-conscious by design. This tool needs an internet connection for part of its work (for example, fetching a public resource). Only the data required for that step leaves your device — nothing is logged or stored, and everything else runs locally.
Platforms cache previews aggressively. Re-scrape the URL in the Facebook Sharing Debugger or X Card Validator to refresh.
1200×630 is the safe universal choice — it fills large cards on Facebook and LinkedIn without cropping surprises.
