How It Works

Our Facebook link preview generator fetches the Open Graph meta tags from your URL and renders a pixel-accurate preview of how your link will appear on Facebook.

Paste your URL: Enter any public web address — a blog post, product page, landing page, or homepage.
Click "Preview Link": Our server fetches the page using Facebook's own crawler user-agent and extracts the og:title, og:description, og:image, og:site_name, and og:type tags.
See the preview: View a Facebook-style link card exactly as it would appear in a post or message.
Check the analysis: The Meta Tag Analysis table shows which tags are present and which are missing, so you know exactly what to fix.

Why Open Graph Tags Matter

Click-Through Rate

Links with a compelling image and clear title get significantly more clicks than plain-text links. A well-crafted preview is the difference between a post that gets ignored and one that drives real traffic.

Brand Credibility

A polished link preview — with a proper logo or featured image, a sharp title, and a concise description — signals professionalism and builds trust before anyone even clicks.

Control Your Message

Without OG tags, Facebook picks a random image and snippet from your page — often something that looks broken or confusing. OG tags let you control exactly what people see.

Works Everywhere

Open Graph tags aren't just for Facebook — they also power link previews on Twitter/X, LinkedIn, WhatsApp, Slack, and iMessage. Fix them once and look great everywhere.

Frequently Asked Questions

What are Open Graph tags?

Open Graph tags are HTML meta tags placed in your page's <head> section that define how your page appears when shared on social media. The key ones for Facebook are og:title, og:description, and og:image. Without them, Facebook has to guess — and usually gets it wrong.

Why is my Facebook link preview showing the wrong image?

Facebook caches link previews aggressively. Even after fixing your og:image tag, the old preview may persist for days. Use Facebook's Sharing Debugger to force a cache refresh. Also make sure your image is at least 1200×630 pixels and publicly accessible (not behind a login).

Why is my og:image missing from the preview?

A missing og:image is usually caused by: (1) the og:image tag not being in the HTML at all, (2) a relative image URL instead of an absolute one like https://example.com/image.jpg, (3) the image server blocking crawlers, or (4) the image being too small. This tool shows you whether the tag is present and what URL it contains so you can diagnose the issue quickly.

How do I fix my Facebook link preview?

Step 1: Add the missing tags to your page's <head>. Step 2: Ensure og:image is a full absolute URL pointing to a 1200×630 image. Step 3: Use Facebook's Sharing Debugger to clear the cache. Step 4: Run this tool again to confirm everything looks right.

What is the ideal og:image size for Facebook?

Facebook recommends 1200×630 pixels at a 1.91:1 aspect ratio. The minimum is 600×315 pixels — below that, no image will show. Keep the file size under 8MB and use JPEG or PNG. Avoid putting important text near the edges, as Facebook may crop the image slightly depending on placement.

Is this Facebook link preview tool free?

Yes, completely free to use. No account or signup required. Paste your URL and see your Facebook link preview instantly. Guest users can check up to 20 URLs per day.
