What is OpenGraphPreviews.com?

What are Open Graph tags?
Open Graph (OG) tags are HTML meta tags placed in the head of a webpage that control how links appear when shared on Facebook, LinkedIn, Twitter/X, Discord, WhatsApp, and Slack. The core tags are og:title, og:description, og:image, and og:url. Without them, platforms guess — producing broken or unappealing link previews that hurt click-through rates.
How to add Open Graph tags to your website
Use the OG Tag Generator to create ready-to-paste HTML: fill in your title (40-60 chars), description (120-160 chars), a 1200x630px image URL, and your page URL. Copy the generated snippet and paste it into your page head tag or CMS SEO field.
Social card previews for every platform
Preview Builder shows live social card previews for Facebook, LinkedIn, Twitter/X, and Discord. The URL Inspector checks any live URL and extracts all OG meta tags. The Image Validator confirms your og:image is reachable and the right size. The OG Tag Generator outputs complete HTML with both Open Graph and Twitter Card tags.
Recommended Open Graph image size
The optimal og:image size is 1200 x 630 pixels (aspect ratio 1.91:1). Minimum for large cards: 600 x 315 pixels. Keep the file under 1MB. Use JPG, PNG, or WEBP formats. Below the minimum, Facebook shows a tiny thumbnail instead of a large social card.
Why Open Graph tags matter for SEO and click-through rates
Open Graph tags directly improve click-through rates when links are shared on social media. A compelling og:image and og:title produce rich social card previews instead of plain URL text. Higher CTR from social shares improves referral traffic and brand visibility, making OG tag optimisation one of the highest-ROI technical SEO tasks.
Frequently Asked Questions
- Is OpenGraphPreviews.com free?
- Yes, completely free with no account, no sign-up, and no usage limits.
- How do I check my Open Graph tags for free?
- Use the URL Inspector tab. Paste any public URL and click Inspect — the tool fetches the page and extracts every OG and Twitter Card meta tag, flagging missing or malformed values.
- Is this a Facebook Sharing Debugger alternative?
- Yes. OpenGraphPreviews.com works for all platforms simultaneously and requires no login, unlike the Facebook Sharing Debugger. Get previews for Facebook, LinkedIn, Twitter/X, and Discord side by side.
- Why does my Facebook link preview look wrong?
- Usually caused by a missing og:image, an image that is not publicly accessible, or Facebook serving a stale cached version. Use the URL Inspector to diagnose the issue, then use Facebook's Sharing Debugger to force a cache refresh.
- How do I fix my LinkedIn link preview?
- Ensure og:title, og:description, and og:image are all set. After updating your tags, paste the URL into LinkedIn's Post Inspector to clear the cache. Preview the result in the Preview Builder tab here first.
- What is the difference between Twitter Cards and Open Graph?
- Twitter Cards use twitter:* meta tags but fall back to OG tags if none are present. Best practice is to set both. The OG Tag Generator outputs both sets automatically.
- How do I add Open Graph tags to WordPress?
- Use Yoast SEO, Rank Math, or All in One SEO — they add OG tags automatically. For manual control, generate your tags here and paste them into your theme's header.php or a custom header plugin.
- What size should an Open Graph image be?
- 1200 x 630 pixels (1.91:1 aspect ratio). Minimum 600 x 315 px. Under 1MB file size. JPG, PNG, or WEBP format.
- Can I generate Open Graph tags automatically?
- Yes. The OG Tag Generator tab outputs a complete, copy-ready HTML block with all Open Graph and Twitter Card tags filled in.
- Does this tool store my data?
- No. The Preview Builder and OG Tag Generator run entirely in your browser. The URL Inspector fetches page HTML only to extract meta tags and immediately discards it — no URLs or data are stored.
