LinkedIn Post Preview & OG Tag Checker
Preview how your link appears as a LinkedIn post card and check the Open Graph tags LinkedIn reads. Helps fix cached old images, wrong images, and sub-minimum image sizes.
LinkedIn Post Preview & OG Tag Checker
LinkedIn reads standard Open Graph (og:) tags to build its link card and recommends an image around 1200 × 627. It caches the first preview it scrapes aggressively — often for about 7 days — so changes won't appear in new posts until the cache expires or you force a refresh.
Paste your URL to preview the LinkedIn card and inspect the tags it reads. To bust LinkedIn's cache, run the URL through the official Post Inspector at linkedin.com/post-inspector, which forces a fresh scrape.
Frequently asked questions
How do I clear LinkedIn's cache for a link preview?
Use the LinkedIn Post Inspector at linkedin.com/post-inspector — paste your URL and it forces LinkedIn to re-scrape the page and refresh its cached preview. LinkedIn caches previews for roughly 7 days, and the Post Inspector is the only reliable way to bust that cache before then. After inspecting, the new image should appear in fresh posts.
What image size does LinkedIn want for link previews?
Use 1200 × 627 pixels (essentially the standard 1.91:1 OG ratio) for a full-width LinkedIn link card. The image should be at least 1200 × 627; smaller images may render as a small thumbnail or be rejected. LinkedIn reads standard og:image tags, so a 1200 × 630 image works fine too.
Why does LinkedIn keep showing my old image after I updated it?
LinkedIn aggressively caches the first version of a preview it scraped, so changes won't appear until the cache expires (about 7 days) or you force a refresh. Run the URL through the Post Inspector to re-scrape it immediately. If that still shows the old image, append a query parameter (e.g. ?v=2) so LinkedIn treats it as a brand-new URL.
Why does my image work in Post Inspector but not when I actually post?
This usually means LinkedIn had already cached an older or broken preview before you fixed your tags — the Inspector shows the fresh scrape while the composer still serves the cached one. Re-run the Inspector to refresh the cache, then start a new post. A wrong-size or inaccessible image, or og: tags injected by JavaScript, can also cause "Cannot display preview" in the app.
Why is LinkedIn pulling the wrong image from my page?
LinkedIn either cached a previous og:image or, if no valid og:image is found, falls back to grabbing some other image on the page. Make sure you have one explicit, absolute og:image tag in the server-rendered HTML, then re-scrape with the Post Inspector to overwrite the cached wrong image. Confirm the image meets the 1200 × 627 minimum so it isn't skipped.
