Open Graph, Twitter Cards and WebP

Social scrapers are not Chrome. For public sharing, a 1200×630 JPEG (or PNG) `og:image` is still the reliable choice. Convert every image *on the page* to WebP so the URL you are sharing is fast when someone actually clicks.

Unfurl ≠ LCP

The card image is fetched by Facebook, Slack, LinkedIn. The hero is fetched by the user. Optimise them independently.

Why it matters

  • Broken unfurls look unprofessional.
  • A WebP-only OG image still fails in some tools.
  • The click-through lands on your fast WebP page.

How to do it

  1. Create 1200×630 JPEG <300 KB for og:image and twitter:image.
  2. Convert page assets to WebP.
  3. Absolute HTTPS URLs in meta tags.
Convert a batch in your browser. Nothing is uploaded.
