Link preview and Open Graph check
Check the title, description, og:image, canonical and redirects of a public HTTPS page. Download a report on the source HTML.

How to use
- Paste the full public address of the page.
- Check the redirect chain and the metadata actually received.
- Fix the source page and separately check the card in the target app.
How it works
The server makes one request to the source HTML and follows a maximum of three HTTPS redirects. JavaScript is not executed. Access is restricted to public network addresses, and the HTML size is up to 1 MB. The table shows the Open Graph and Twitter Card fields. The layout selects the title by priority: og:title, then twitter:title, then the regular title. The image is not loaded automatically.
Example
If og:image is absent in the source HTML but appears after JavaScript runs, this checking request will not see it. If the address redirects to another page, examine the final URL and whether the required parameters are preserved. Updated HTML does not mean the app has already updated its cache.
Source: Open Graph: basic properties. The methodology was verified on 24 September 2026.
Questions about the tool
Why does the card look different in Telegram?
Telegram uses its own bot, cache and display rules. The site's response may also be affected by region, access and request headers. This mockup is not an exact copy of the app.
Does the check reset the old image?
No. It shows the result of a new Boosted request. Corrections need to be made on your site, and the cache update should be checked separately in the relevant service.
