Open Graph Preview Tester
Ever shared a link on Facebook or LinkedIn and the preview looked completely wrong? Maybe the image was missing, the title was cut off, or the description showed something embarrassing. Our OG Preview Tester lets you see exactly how your webpage will look when shared on social media before you hit send. Just paste your URL and get an instant preview showing the title, description, and image that will appear. No more ugly surprises in your feed. Test your page across multiple platforms and make sure your Open Graph tags are doing their job.
What Is
An OG Preview Tester is a tool that shows you exactly how a webpage will appear when shared on social media platforms like Facebook, LinkedIn, WhatsApp, and X. When someone pastes a URL into a social post, the platform fetches the page's Open Graph meta tags to build a rich preview card with a title, description, and image. If those tags are missing, incorrect, or poorly formatted, the preview can look broken — wrong image, truncated title, missing description, or just a plain text link. The OG Preview Tester simulates this process so you can see what others will see before you share. It pulls the Open Graph tags from your page and renders them in a visual preview that mimics how different platforms display shared links. This is incredibly useful because each platform has different display rules. Facebook might show a large image with the title below, while LinkedIn uses a different aspect ratio, and WhatsApp shows a smaller preview. A tag that looks perfect on one platform might get cropped awkwardly on another. Testing beforehand lets you catch these issues and fix your tags so your links always look professional and clickable.
How to Use
- Copy the URL of the webpage you want to test — make sure it's a publicly accessible page, not behind a login or on a local server.
- Paste the URL into the OG Preview Tester's input field and click the preview or test button to fetch your page's Open Graph data.
- Review the generated preview card showing the title, description, and image that will appear when your link is shared on social media.
- Check how the preview looks across different platform styles — some testers show Facebook, LinkedIn, and WhatsApp variations side by side.
- If anything looks off, go back and update your Open Graph tags, then re-test until the preview looks exactly how you want it to appear.

Frequently Asked Questions
Why does my shared link show the wrong image?
This usually happens when your page either doesn't have an og:image tag, the image URL in the tag is broken, or the image dimensions aren't ideal. Facebook prefers images at 1200x630 pixels. If your image is too small, Facebook might ignore it and pull a different image from your page instead. Always specify an og:image tag with a high-quality image at the recommended size to maintain control over what appears.
My page has Open Graph tags but the preview still looks wrong. Why?
Social platforms cache Open Graph data, so if you recently updated your tags, the old version might still be showing. Facebook's cache can last for days. Use Facebook's Sharing Debugger tool to scrape your page and clear the cache. Also double-check that your og:image URL is absolute (starting with https://) rather than relative, as some platforms don't resolve relative URLs correctly.
Can I test a page that's not live yet?
Most OG Preview Testers require the page to be publicly accessible on the internet. If your page is still in development, you can use a staging URL if it's publicly available, or temporarily deploy it to test. Some advanced tools also let you paste raw HTML or Open Graph tag code directly for testing without a live URL.
Do I need different Open Graph tags for different platforms?
The standard Open Graph protocol works across Facebook, LinkedIn, WhatsApp, and most other platforms. However, X (Twitter) uses its own Twitter Card tags in addition to OG tags. For best results everywhere, include both standard OG tags and Twitter Card tags. The core og:title, og:description, and og:image will cover most platforms, while twitter:card and twitter:image handle X specifically.
How long does it take for updated Open Graph tags to show up when I share?
Once you update the tags on your live page, they're technically available immediately. However, social platforms cache the data, so if you've shared the link before, the old preview might still appear. You'll need to use each platform's debugger tool to force a re-fetch. Facebook's Sharing Debugger, LinkedIn's Post Inspector, and Twitter's Card Validator all let you clear the cache and see the updated preview.
