Open Graph checker
Check the Open Graph tags and share card of any page
Paste a public URL. The checker reads og:title, og:description and og:image, measures the share image and draws the card for LinkedIn, Facebook, X and messaging apps.

LinkedIn approximation
What one check gives you
The three required tags
og:title, og:description and og:image, each with the value found on that fetch. A tag that is not there is listed as Missing.
The real image size
With Verify image URL ticked, the share image is fetched and its width and height are read from the PNG or JPEG file, then compared with og:image:width and og:image:height.
Share cards per platform
Cards for LinkedIn, Facebook, X and messaging apps, or just one pair. Each card is labelled an approximation, because networks crop and cache on their own.
Warnings the check can raise
- og:title, og:description or og:image is missing
- The image address does not return an image content type
- The image was fetched, but its PNG or JPEG size could not be read
- The declared width or height differs from the real one

Checking the title, text and image behind a shared link
What you check in one run
You paste a page URL or upload the page's HTML. One page is checked per run. The tool reads the Open Graph tags for title, description and share image from that page. Every value it reports comes from what it actually found on that fetch. A redirect or a 404 on the address shows up as such, rather than as missing metadata.
How to read the cards
Each card is labelled as an approximation. Networks crop and cache previews on their own schedule, so the cards show what your tags declare, not a promise of what a given network will draw.
What the tool will not do
Nothing is sent to any platform, and no cache is refreshed. If a network still shows an old image after you fixed the tags, use that network's own debugging tool.
Questions before you run it
Do I need an account?
Yes, a free account. It includes 3 free jobs a day, and failed jobs are not counted. Pro raises this to up to 200 jobs a day.
Which metadata tags are inspected?
The required Open Graph fields for title, description and share image, read from the page you supply as a URL or as an uploaded HTML file. Every value shown comes from the metadata observed on that fetch.
Why does the preview call itself an approximation?
Platforms crop, re-render and cache share cards on their own schedule, and none of them publish the exact rules. The cards show what your metadata declares; they are not a promise of what a given network will draw.
Can it refresh a stale preview on Facebook or LinkedIn?
No. Nothing is pushed to any platform and no cache state is claimed. If a network still shows an old image, you need that network's own debugging tool.
Does it verify that the share image actually loads?
Verify image URL is a checkbox. With it on, the image is fetched under bounded limits and its decoded width and height are reported, which is how an undersized or missing og:image comes to light.
How many pages can one job cover?
One page per run. The HTTP evidence file records the request that was made, so a redirect or a 404 on the supplied URL is visible instead of showing up as missing metadata.
