Free Open Graph Checker

LinkedIn Preview Tool

Check how a public URL may appear when shared on LinkedIn. Find missing required tags, canonical problems, redirects, image issues, and the correct next step for stale previews.

The page must be public and use HTTPS. No account is required.

How it works

Check a LinkedIn link preview in three steps

01

Enter your URL

Paste the full HTTPS address of a public page.

02

Check the metadata

The tool reads the page status, canonical URL, and Open Graph tags.

03

Fix the warnings

Review missing tags, text length, image size, and redirect details.

Open Graph guide

What your page should include

A clear title

og:title controls the main headline in the preview. Keep it specific, readable, and consistent with the page.

A useful description

og:description should explain why somebody should open the link. Do not repeat the title or fill it with keywords.

An absolute image URL

og:image should use a complete HTTPS URL. A 1200 by 627 pixel image is a reliable target for a wide LinkedIn preview. Keep important text and faces away from the edges because cropping can vary.

The canonical page URL

og:url and the canonical link should point to the preferred public version of the page. Avoid tracking parameters and redirecting URLs.

LinkedIn currently lists all four tags as required. Its sharing guidance specifies a maximum image file size of 5 MB, minimum dimensions of 1200 by 627 pixels, and a recommended 1.91:1 ratio. This browser-based check cannot reliably confirm the compressed file size.

Troubleshooting

Fix the most common LinkedIn preview problems

The old image still appears

Confirm the live page returns the new og:image, then submit the final canonical URL to LinkedIn Post Inspector. A refresh changes previews for new posts, not posts that already exist.

No image appears

Check that og:image exists in the page source and that the image is public. LinkedIn warns that protected directories or access rules can prevent it from retrieving an otherwise valid image.

The image becomes a thumbnail

Use an image that meets LinkedIn's sharing requirements. LinkedIn states that images below 401 pixels wide display as thumbnails, while its current sharing guidance calls for at least 1200 by 627 pixels.

The wrong URL or content appears

Inspect the final URL after redirects. Make og:url and rel=canonical agree, and do not submit a tracking URL when a stable canonical URL is available.

The title or description is missing

Add dedicated og:title and og:description tags to the HTML source. A browser title or meta description is useful as a fallback, but LinkedIn lists the Open Graph tags as required.

The preview differs after publishing

Treat this page as a diagnostic simulation. LinkedIn controls its final rendering and may crop or truncate content. Confirm the actual result in LinkedIn before publishing.

Important difference

Preview checker versus LinkedIn Post Inspector

This is an independent preview and Open Graph diagnostic tool. It shows the metadata your page returns and highlights common problems before you share the link.

It cannot clear LinkedIn's cache. If LinkedIn is still showing an old title or image after you update the page, use the official LinkedIn Post Inspector. That tool asks LinkedIn to inspect the URL again.

First fix the warnings shown here. Then use LinkedIn's official tool when you need its cached preview refreshed.
