Frequently Asked Questions

Browsers enforce CORS (Cross-Origin Resource Sharing), which prevents client-side JavaScript from directly fetching HTML from arbitrary URLs. The PHP proxy (or allOrigins fallback) solves this by fetching the page server‑side, where CORS doesn't apply.

Some sites (especially SPAs built with React/Angular) inject OG tags dynamically via JavaScript. Our PHP proxy does a basic HTTP fetch and won't execute JavaScript. For SPAs, use tools like the Facebook Sharing Debugger which renders the page fully before scanning.

Facebook recommends 1200×630 pixels (1.91:1 aspect ratio). Twitter recommends 1200×675 for summary_large_image cards. Images smaller than 600×315 may not be displayed at all.
