Check the tags that decide your link preview
LinkPeek reads your page metadata and shows the title, description, image, URL, and card layout that social crawlers rely on.
- Validate og:title, og:description, og:image, og:url, and og:type
- Catch missing absolute image URLs before the link is shared
- Compare Open Graph output against Twitter/X, LinkedIn, WhatsApp, Slack, Discord, and Instagram-style cards
Useful before launch and after metadata changes
Use the checker while building a new page, refreshing a landing page, or debugging a card that is already cached on social platforms.
- Paste a production URL or a localhost URL
- Review platform-specific warnings in the audit panel
- Copy fix tags for your framework or CMS head section
Frequently asked questions
What is an Open Graph preview tool?
An Open Graph preview tool checks the metadata social apps use to generate link cards, including title, description, image, and canonical URL.
Can LinkPeek preview OG images before publishing?
Yes. LinkPeek can test a live URL and also supports localhost preview workflows for checking metadata before a public deploy.
Why does my Open Graph image not show?
Common causes include a missing og:image tag, a relative image URL, a blocked crawler, an unsupported image format, or an image that is too small or too large for the target app.
