LinkedIn Post Inspector Alternative

What LinkedIn needs

LinkedIn builds the card from og:title, og:description, og:image and og:url.
Image: at least 1200×627 pixels, a 1.91:1 ratio, at most 5 MB.
The page is fetched by LinkedInBot; it has to reach the page without a login or a bot challenge.
LinkedIn documents Post Inspector as the way to refresh a preview after you change the tags.

LinkedIn link preview not showing or not updating?

No image or a small one? LinkedIn documents 1200×627 as the minimum — smaller images show small or not at all.
Keep the file under 5 MB and the URL absolute (https://).
Changed the tags? Paste the URL into Post Inspector (signed in) to make LinkedIn fetch the page again; existing posts keep their old card.
Check that robots.txt and your firewall let LinkedInBot in.
Avoid redirect chains and login walls on the shared URL: the crawler sees what an anonymous visitor sees.

A preview image for every page, on LinkedIn and everywhere else

Most broken previews have no image at all. Shareglint renders one for every page from its title — one meta tag, no code — at a size that passes every documented limit (the sizes). 100 images a month free.

Questions

Can I use LinkedIn Post Inspector without an account?

No, Post Inspector needs you signed in to LinkedIn. This page previews the LinkedIn card from your tags with no account; to force LinkedIn itself to refresh its cache, you still need Post Inspector.

What is the LinkedIn link preview image size?

LinkedIn documents a minimum of 1200×627 pixels, a 1.91:1 ratio and 5 MB at most. 1200×630 meets all three.

Why does LinkedIn show an old image?

LinkedIn caches previews. Run the URL through Post Inspector after the change; a post you already published keeps the card it had.
