Open Graph & Social Preview
Free, no signup. See which tags each social surface will use, where the text is likely to truncate, and whether the image is ready to share.
The selected UA is stated above. This is a point-in-time fetch from this site — not Facebook, X, or LinkedIn’s cache.
Checks run from our server; we fetch the URL you enter and don't keep the results. The page URL is sent to this site's bounded fetcher. Image dimensions load in your browser; only image type and declared size are probed server-side. Anonymous run-level outcome counters may be used for aggregate research; URLs, domains, IPs, and identifiers are never included, and no statistic is released below 100 runs.

How to use it
- Fetch a public URL, paste staging HTML, or start from scratch.
- Compare the eight cards and their stated source fields.
- Edit the fields and copy the tag block.
- Test the published URL in the platform's own debugger.
How it works
The tool parses fetched or pasted HTML locally for og:, twitter:, title, and meta-description fields. Live URL runs can also probe the chosen image.
Features
- Eight platform cards with source provenance.
- URL, pasted HTML, blank-editor, and fictional-example entry points.
- Live editing and copyable meta tags.
Sample report
The fictional example seeds a 1200×630 image, title, and description and uses the same readiness scorer as a live run.
Limitations
- This cannot reproduce private platform caches or experiments.
- Pasted HTML cannot verify headers, redirects, image bytes, or crawler access.
- Use each platform's debugger for final validation.
Frequently asked questions
Does this refresh a platform cache?
No. It fetches the page directly and shows a local simulation. Use the linked Facebook Sharing Debugger or LinkedIn Post Inspector to request a refresh from those platforms.
Why can my real share card differ?
Platforms fetch from their own IP ranges and caches, may use a different user-agent or region, and apply undocumented rendering details. This preview makes its source keys explicit, but cannot reproduce every platform cache.
Does the image leave my browser?
The entered page is fetched through this site’s bounded HTML fetcher. The image itself loads directly in your browser for dimensions; a small server-side probe checks its type and declared size.

よくある質問
SNSで同じ見た目になることを保証しますか？
いいえ。SNSのキャッシュ、クロール、画像制限、プラットフォーム仕様により表示は変わります。
編集したタグはページへ書き込まれますか？
いいえ。ブラウザー内のコピー用編集です。公開するには自分のサイトで変更してください。
取得に失敗するのはなぜですか？
robots、認証、リダイレクト、TLS、User-Agentの分岐などでレスポンスが得られない場合があります。
