How to preview Open Graph and social card meta tags before publishing?

Use AnyTool OG Image Preview: paste a page's head HTML or its og: and twitter: meta tags, or fill the form, and instantly see faithful Facebook, X, LinkedIn, Slack, Discord, WhatsApp, Telegram, Pinterest and Google cards. It validates tags and generates clean meta code, 100% in your browser with no upload.

  • Preview 9 social cards live as you type, with per-platform title and description truncation
  • Works on localhost, staging or behind-auth pages by pasting their head - no public URL needed
  • Validates missing, duplicate and oversized tags and reads og:image dimensions locally
  • 100% in your browser - no upload, no signup, works offline

Frequently Asked Questions

No. Everything is parsed and previewed locally in your browser - nothing is uploaded.

No. AnyTool OG Image Preview parses your pasted HTML or meta tags with the browser-native DOMParser and renders every card on your device. No HTML, tags or images are sent to a server, so even unpublished or internal pages stay private.

Yes. Paste the page head HTML or meta tags and it previews instantly, no public URL required.

Yes. Because the tool reads tags from text you paste rather than fetching a URL, you can preview localhost, staging or behind-auth pages by copying their head HTML. You can also upload an unpublished og:image as a private blob URL to see it in every card.

No. Browsers cannot read another site's HTML due to CORS, so you paste the head or tags instead.

No. A browser cannot fetch an arbitrary cross-origin site's HTML to read its tags because CORS blocks it. The private, always-works path is to open the page, View Source, and paste its head or meta tags. For a live server re-scrape after publishing, link out to the official Facebook and LinkedIn debuggers.

Fill the form fields, then copy the generated, HTML-escaped OG and Twitter meta block into your head.

Switch to the form, fill og:title, og:description, og:image, og:url, twitter:card and related fields, and the tool produces a clean, HTML-attribute-escaped meta block. Copy it and paste straight into your page head; a live validator flags anything missing, duplicated or wrongly sized as you edit.

Detailed Explanation

How It Works

Client-Side Open Graph and Social Card Preview

AnyTool OG Image Preview turns og: and twitter: meta tags into faithful visual cards for nine surfaces: Facebook, X/Twitter (summary and large image), LinkedIn, Slack, Discord, WhatsApp, Telegram, Pinterest and a Google search result. Input comes from pasted head HTML, raw meta tags, or a form, parsed with the browser-native DOMParser. Every card re-renders live on each edit, applying each platform's own image aspect ratio and title and description truncation rules.

  • Nine platform cards rendered from one set of meta tags
  • Parses pasted HTML or tags with native DOMParser - extracts og:*, twitter:*, title, description, canonical, theme-color and favicon
  • Live validator flags missing, duplicate and oversized tags and checks the 1.91:1 image ratio
  • Generates a clean, HTML-attribute-escaped OG and Twitter meta block to copy
Use Cases

Previewing Localhost, Staging and Unpublished Pages

Because the tool reads tags from pasted text rather than fetching a live URL, it can preview pages that are not publicly reachable, such as localhost, staging environments or pages behind authentication. Users open the page, View Source, and paste its head. An og:image that is not yet deployed can be uploaded locally and shown in every card as a private blob URL.

  • Preview localhost, staging and behind-auth pages by pasting their head HTML
  • Upload an unpublished og:image as a private blob: URL
  • Image natural width, height and aspect ratio are read locally with a plain Image load
  • No public URL, signup or login required
Limitations

Honest Limit: No Cross-Origin URL Fetch or Cache Refresh

A browser cannot fetch an arbitrary cross-origin site's HTML to read its meta tags because CORS blocks it, so the tool does not auto-fetch a third-party URL; pasting the page head or tags is the primary, private path. Likewise, a client-side tool cannot force Facebook or LinkedIn to re-scrape and refresh their server-side cache, so the tool links out to the official debuggers for that one action. Cross-origin og:images that the host blocks may fail to load, in which case the user can upload the image locally.

  • Cannot read another site's HTML directly - CORS prevents cross-origin fetch
  • Cannot bust Facebook or LinkedIn server caches - links to official debuggers instead
  • Card chrome is a faithful visual approximation, not a byte-identical render
  • Parsing, validation, code-gen and previews all run offline with no upload
