What Open Graph fields does this preview?

It simulates link cards using og:title, og:description, og:url, og:image, og:site_name, and og:type, then emits matching meta property tags you can copy.

Does the tool fetch my og:image?

No remote fetch. The image area is a layout placeholder. Paste an absolute image URL into the HTML output for real crawlers; this UI does not download the file.

Will Facebook or Slack match this layout exactly?

No. Each platform crops and caches differently. Treat this as a structural preview for drafting tags, not a pixel-perfect guarantee.

Why must image URLs be absolute?

Most social crawlers require absolute https URLs for og:image. Relative paths often fail silently when links are shared.

Is Twitter Card markup included?

This tool focuses on Open Graph. Many platforms fall back to OG tags; add twitter:card tags separately if you need platform-specific control.

No remote fetch

Image areas are placeholders—this tool does not fetch og:image.

Open Graph Preview helps you draft og:title, description, URL, image, and type tags with simulated link-card layouts—locally in the browser, without fetching remote images or pages.

How it works

Fill Open Graph fields and review Facebook-style and compact card mockups. The tool generates meta property HTML for copy or download. Image slots are placeholders; no network request is made for og:image.

Benefits

Side-by-side large and compact card layout mocks
Copyable Open Graph meta property tags
No remote crawl or image download
Type selector for website, article, product, and profile

Use cases

Prep OG tags before shipping a landing page
Review share copy with marketing without deploying
Export starter meta tags for a static site head
Check that titles remain readable when truncated

Best practices

Use absolute https URLs for og:url and og:image
Prefer ~1200×630 images for large link previews
Keep titles specific; avoid duplicating the entire H1 twice
Re-scrape caches on platforms after you change tags

Common mistakes

Assuming this mock equals every network’s final card
Using relative image paths that crawlers cannot resolve
Leaving og:description empty when the page has weak excerpt text
Forgetting to update cached previews after edits

Privacy

Open Graph Preview processes your inputs locally. ToolHub does not fetch your page or image URL for this tool.
