- Where do I put the generated tags?
- Paste them inside the head section of your page's HTML, then publish. If you use a site builder or CMS, look for an SEO or custom head code setting where you can add them. They must be on the live page for platforms to read them.
- I updated my tags but the old preview still shows. Why?
- Platforms cache previews to load them quickly, so your change may not appear until they re-fetch your page. Most offer a debugging or refresh tool that forces an update. Our social preview checker helps you see the current card and points you to the right refresh option.
- What image size should I use?
- For a large card, 1200 by 630 pixels is the widely supported size. Use a publicly hosted image URL, not a local file, because platforms fetch it from the web. A landscape image works best. Small or oddly shaped images may show as a thumbnail or not at all.
- Does this handle both Facebook and X?
- Yes. It writes Open Graph tags, which Facebook, LinkedIn, WhatsApp, Slack and most platforms read, and Twitter Card tags for X, from the same inputs. You get one block of HTML that covers both.
- Is my data sent anywhere?
- No. The generator runs in your browser. What you type is used to build the tags on your device and is not sent to us or stored. The preview image URL you supply is simply written into the tags; we never fetch or host the image.
