Live checker
Test a URL in the Link Preview Checker
Use LinkPeek as a link preview checker when you want to see how a URL will appear before it is shared in feeds, chat apps, workspaces, DMs, or launch posts. It combines visual social card previews with a metadata audit, so you can fix title, description, image, crawler, and cache issues from one workflow.
See the share card before your audience does
A link preview is often the first visual impression of a page. If the title is vague, the image is missing, or the description is stale, people may ignore the link even when the page itself is strong.
- Preview title, description, thumbnail, image crop, and destination URL
- Compare multiple app-style cards in one place
- Use audit findings to patch weak or missing metadata
Useful for marketers, founders, agencies, and developers
Link preview QA matters for product launches, campaign pages, newsletters, blog posts, documentation, communities, and client reporting. LinkPeek gives non-technical users a clear visual check and gives developers precise metadata problems to fix.
- No sign-in required for quick checks
- Works across public URLs and local development workflows
- Pairs single-page inspection with bulk launch QA
Move beyond generic tag output
Raw metadata can be technically valid but visually weak. LinkPeek shows the card itself so teams can judge whether the headline reads well, the image crop works, and the preview supports the share intent.
- Catch truncation before posting
- Check cross-platform card differences
- Export or share results during review workflows

Common issues this page helps debug
The link preview is blank
Blank cards usually mean metadata is missing, hidden behind JavaScript, blocked by robots, or served with an image URL crawlers cannot fetch.
The wrong image appears
Look for stale cache, multiple OG images, canonical mismatches, or old CMS data.
The preview copy is not page-specific
Generic site descriptions are common. Use page-level title and description values for important URLs.
Only one platform is broken
Each app has its own crawler and card rules. A preview can work on X but fail on WhatsApp or Slack.
Frequently asked questions
How do I check a link preview?
Paste the URL into LinkPeek and run a scan. The tool fetches metadata, renders social card previews, and reports missing or weak tags.
Which social previews can LinkPeek check?
LinkPeek previews WhatsApp, LinkedIn, X, Slack, Discord, Instagram-style cards, Twitter Cards, and Open Graph metadata.
Does a link preview checker update cached previews?
No. A checker diagnoses and verifies metadata. Some platforms still require a cache refresh or cache-busted URL after fixes.
Can I check multiple URLs?
Yes. Use the Bulk Link Preview Checker to scan up to 100 public URLs in one run.
