LinkedIn Post Inspector alternative

SocialImageKit is an independent tool — not affiliated with LinkedIn. LinkedIn’s official Post Inspectorstill owns cache refresh. What we add: an instant, no-login preview of the tags crawlers see so you fix the page before you scrape.

How it works

How LinkedIn builds a link preview

When someone posts a URL, LinkedIn’s crawler fetches the public HTML and reads Open Graph tags. The usual fields are og:title,og:description, og:image andog:url. Twitter Card tags are not a substitute for LinkedIn.

For the image, aim for about 1200×627 (1.91:1). LinkedIn’s help docs treat that size as the working floor for a full-width card. Absolute minimums around200×200 exist, but small files often become thumbnails. Keep the file under 5 MB (closer to 200–800 KB is kinder to mobile).

Stuck preview

Why your LinkedIn preview is not updating

  • Cache. LinkedIn can keep a scraped card for roughly a week. Editing a post alone does not force a new fetch. After the live page is correct, usePost Inspectorto scrape again.
  • Wrong image size. Far-from-landscape files get cropped or shrunk. Rebuild near 1200×627.
  • Image not public. Hotlink protection, signed URLs, or a 403 to bots looks like “no image” in LinkedIn.
  • robots.txt. If LinkedInBot is disallowed, Inspector cannot read the page you think you fixed.
  • Relative og:image. Paths like /og.jpg fail; use a full https URL.
  • Redirects. Long redirect chains or a different final URL than the one you inspected can leave the feed on an old scrape.

No LinkedIn login

Paste the public URL into the Link Preview Checker. Confirm title, description and image, then scrape with official Post Inspector if the feed is still stale.

Before you post

Checklist before you post

  • Canonical https URL opens without login.
  • og:title, og:description, og:image and og:url are in View Source (not only after JS).
  • og:image is an absolute https URL returning 200 anonymously.
  • Image is about 1200×627 (1.91:1), under 5 MB (aim under 1 MB).
  • Important text sits inside a safe margin — LinkedIn crops edges.
  • If you changed artwork, use a new image path so caches cannot reuse the old file.
  • Run this site’s Link Preview Checker, then scrape with official Post Inspector.

Troubleshoot

Common problems and fixes

Scroll sideways on small screens. Start with cache and absolute URLs — they cause most “not updating” reports.

Frequently asked questions

Answers about LinkedIn cache, image crop, Post Inspector, and how this independent checker fits in.

How do I clear LinkedIn cache for a link?

Update the live page first (absolute og:image, preferably a new image path). Then open LinkedIn’s official Post Inspector, paste the canonical https URL, and request a scrape. Share again in a new post if the feed still shows the old card.

Why is my LinkedIn image cropped?

LinkedIn lays out a wide card near 1.91:1. Tall or square files get cropped. Keep the headline and logo inside a ~10% inset and design at about 1200×627.

Is the LinkedIn Post Inspector free?

Yes. LinkedIn’s official Post Inspector is free and does not require a paid LinkedIn plan to scrape a public URL. This site’s checker is also free and does not require a LinkedIn login.

What size should a LinkedIn link preview image be?

Use about 1200×627 pixels (1.91:1). LinkedIn’s help docs treat 1200×627 as the working minimum for a full-width card; images under roughly 401px wide often collapse to a thumbnail. Stay under 5 MB.

Why is my LinkedIn preview not updating?

Usually cache: LinkedIn can keep an older scrape for roughly a week. Other causes are relative image URLs, files that need a login, robots.txt blocking LinkedInBot, or tags that only exist after JavaScript runs.

Is SocialImageKit affiliated with LinkedIn?

No. SocialImageKit is an independent site. We are not affiliated with, endorsed by, or sponsored by LinkedIn or Microsoft. Use official Post Inspector when you need LinkedIn’s own cache refresh.
