What is Social Media Preview?
Social Media Preview shows how your link will look when it is shared, rendering Google, X, LinkedIn, and Facebook cards side by side from your title, description, URL, and image. Character counters flag titles and descriptions that run past the usual truncation points, and a ready-to-paste block of Open Graph and Twitter meta tags is generated as you type. It is a visual mockup that runs entirely in your browser, so nothing you enter is uploaded.
How to use Social Media Preview
Enter your page details
Type the page title and meta description. Live counters show 60 characters for the title and 160 for the description, turning red when you go over the recommended length.
Set the URL
Paste the page URL. The tool extracts the domain and displays it exactly as it will appear on the cards.
Add a social image
Drop in a 1200 x 630 image, or click Use placeholder to generate a gradient stand-in on a local canvas. The image is used only for the preview and is never uploaded.
Review each platform card
See how the link renders as a Google search result and as X, LinkedIn, and Facebook link cards, so you can catch awkward cropping or truncation before publishing.
Copy the meta tags
Copy the generated Open Graph and Twitter card meta tags and paste them into your page's <head> so real platforms render the card the way you intended.
Common uses
- Check how a blog post or landing page will look when shared before you publish
- Tune a title and description to fit within each platform's visible length
- Generate correct og: and twitter: meta tags without writing them by hand
- Compare the same link across Google, X, LinkedIn, and Facebook at a glance
- Preview a share card for a client or teammate for quick sign-off
- Sanity-check a social image's aspect ratio and cropping
