Open Graph Checker & Social Preview
Enter a URL or paste the HTML: the tool extracts every social tag, shows the link preview and lists what to fix.
Privacy and cost
This tool requests the public URL you enter from our servers. It is free, rate-limited to prevent abuse, and we do not store the URL or the page content.
How it works
- Enter the page URL, or paste its HTML.
- The tool extracts og:*, article:* and twitter:* tags, then builds approximate previews for Facebook, LinkedIn and X.
- Read the findings (missing fields, lengths, image, og:url vs canonical) and export all the tags as JSON.
Example
A page with a 65-character og:title, og:type article, og:url, a 1200×630 og:image and twitter:card summary_large_image is flagged for: og:title too long (65 characters, about 60 recommended), missing og:description, og:site_name and og:locale, and an image without alt text. The 1200×630 px image size is judged suitable.
What the result means
When a link is shared, platforms read the Open Graph tags, then the X tags, and fall back to the title and meta description. The previews shown here are approximations: each network applies its own layout and caches the data, so use their debuggers as well.
Common problems this tool helps with
- A share that shows an unexpected title or image because tags are missing or contradict each other.
- An image that is too small, relative, or whose ratio is cropped on large cards.
- og:* tags written with name instead of property.
- An og:url that does not match the page's canonical URL.
Frequently asked questions
Are the previews identical to the networks'?
No, they are approximations built from your tags. Facebook, LinkedIn and X have their own layout, truncation and cache rules.
Why does my old image still show on Facebook?
Platforms cache the data they fetched. After a change, use their debugging tool to force a fresh read.
Does the tool load the image?
Your browser loads the image for the preview, without a referrer header. In URL mode the page HTML is fetched by our server; in paste mode it stays in your browser.
