Open Graph Checker

A free OG checker for any website. Check the OG image, meta description, and Open Graph tags on a public website link, then see a link preview for LinkedIn, WhatsApp, Facebook, X, Slack, Discord, and Telegram.

Try digitaldialogue.pk, memetap.pk, or ogscope.pk

How it works

Paste a website link and review the link preview from the public HTML. An account saves nothing.

  1. Step 1

    Enter a URL

    Paste any public http or https address. The system adds a scheme when you leave it off.

  2. Step 2

    Fetch the page

    The server requests the HTML. The page source never comes back to your browser.

  3. Step 3

    Read the tags

    Open Graph tags, Twitter card tags, the title, the meta description, the canonical URL, and the favicon are read.

  4. Step 4

    Review the result

    Estimated cards, a metadata table, an image check, and a short checklist appear together.

Open Graph in short

Open Graph is the set of HTML tags a page can publish so a shared link has a chosen headline, summary, and image. The Open Graph protocol is what Facebook, LinkedIn, WhatsApp, Slack, Discord, and Telegram read when someone pastes that link. Without those tags, the product guesses. The beginner guide on what is Open Graph covers the protocol in more depth.

An Open Graph preview is a reading of that OG data. This Open Graph checker fetches the public page, reads the tags on the server, and draws an estimated card. It does not run JavaScript on the target page, and it is not a promise that Facebook, LinkedIn, or X will show the same pixels.

What are Open Graph tags?

Open Graph tags, often called OG tags, sit in the document head. The ones that shape a link preview are:

  • og:title, the OG title people see as the headline
  • og:description, the short summary under that headline
  • og:image, the Open Graph image beside or above the text
  • og:url, the canonical page you want the click to open
  • og:type, usually website or article

Twitter card tags can override the same fields on X. When a Twitter tag is missing, X may fall back to the matching Open Graph tag.

OG image tester

An Open Graph image is the file named by og:image. It is the picture most link previews try to show. A useful image is large enough to stay sharp after cropping, uses an absolute HTTPS URL, and returns an image when requested. A path like /og.jpg is easy to miss, and it often breaks once the page is shared off your site.

Each check also tests that file: it shows the published URL, the resolved URL, whether the file loaded, and the pixel size when it can be read. The OG image checker guide explains each result. When a page has no image yet, the OG image generator builds one from a template.

What OG image size should you use?

1200 by 630 pixels is the OG image size most often used for a large link preview. JPG, PNG, and WebP are widely supported. This checker reports dimensions only when it can read them, and it warns when either side is under 200 pixels. Important detail should sit near the center, because Facebook and LinkedIn often crop the image to a wide ratio. Crop a file to that size in the browser with the OG image size tool.

How does the Open Graph checker work?

  1. You enter a public URL and press Preview.
  2. A server route fetches the HTML, follows safe redirects, and stops if the host is private or unreachable.
  3. The response is read for Open Graph tags and Twitter card tags.
  4. It also checks the page title, meta description, canonical URL, and favicon.
  5. The page displays estimated social cards, a metadata table, an image check, and a checklist of what it found.

Those steps are the fetch. Read how an Open Graph preview is built if you want the tags behind each card.

Meta description and meta tags

The same pass reads the meta description and the other tags that build a link preview: title, description, canonical URL, favicon, Open Graph, and Twitter cards. For the robots tag, viewport, language, and H1 as well, use the meta tag checker.

That metadata can change how a link looks when it is shared. It is not a ranking score, and this page does not tell you where the URL will sit in search results.

OG debugger vs the Facebook debugger

This OG debugger (Open Graph debugger) shows the tags and an estimated card from a fresh fetch of the public HTML.

The Facebook debugger on developers.facebook.com is a different tool. Facebook uses it to show the card Facebook cached and to ask Facebook to fetch the page again. LinkedIn has its own Post Inspector for the same job. The guide on why Facebook keeps showing the old preview is about that cache. Use the official tools when a platform is still showing an old card.

How to fix missing Open Graph tags

Put the tags in the document <head> of the HTML response, not only in a client-side render. Most social crawlers do not run your JavaScript. A practical starting set looks like this:

<meta property="og:title" content="Page title" />
<meta property="og:description" content="One or two plain sentences." />
<meta property="og:image" content="https://example.com/og.jpg" />
<meta property="og:url" content="https://example.com/page" />
<meta property="og:type" content="website" />
<meta property="og:site_name" content="Example" />
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content="Page title" />
<meta name="twitter:description" content="One or two plain sentences." />
<meta name="twitter:image" content="https://example.com/og.jpg" />

Filled-in sets for articles, products, and homepages are in the Open Graph examples guide.

Use the final public URL in og:url, and use the same URL you want people to land on. When that URL or the image URL redirects, trace redirects hop by hop to find the final address. After you deploy, run the page through this tool. If a platform still shows an old card, its crawler is usually serving a cached copy.

Facebook link preview

A Facebook link preview commonly uses og:title, og:description, og:image, and og:url. Read more in the Facebook link preview guide.

LinkedIn preview

A LinkedIn preview also reads Open Graph tags. A clear OG title, a short description, and a large image matter more than extra Twitter-only tags. The LinkedIn preview guide covers the fields this tool uses for that card.

Twitter preview

A Twitter preview on X still honors the older twitter:card tags. summary is a compact card. summary_large_image is the wide image layout. The Twitter card checker shows which of those tags were present and which layout this tool estimated.

WhatsApp preview

The results also include an estimated WhatsApp card built from the same Open Graph title, description, and image. The guide to the WhatsApp preview covers image size, caching, and why a chat can show no card at all.

Frequently asked questions

What is Open Graph?
Open Graph is a set of HTML tags a page can publish so a shared link has a chosen image, title and description. Facebook, LinkedIn, and most chat apps read those tags when someone shares a website link. This tool fetches the public HTML and shows that OG data. It does not run JavaScript on the page.
What are Open Graph tags?
Open Graph tags are meta tags such as og:title, og:description, og:image, og:url, and og:type. The OG title is the headline. og:description is the summary. og:type is usually website or article. Together they are the OG data a platform uses to build a link preview.
What is an Open Graph preview?
A page suggests an Open Graph preview image, title and description when someone shares its link. Those suggestions live in tags such as og:title, og:description, and og:image. This tool reads the tags from the public HTML and draws an estimated card. A platform can still crop the text, choose a different image, or show an older cached copy.
How do I check my OG image?
Paste a public page URL and press Preview. The OG Image section shows the og:image address. It also shows a preview when the file is reachable. It shows the pixel dimensions when the file provides them. Warnings call out a missing tag, a relative URL, a file that did not load, or an image that is unusually small.
Why is my OG image not showing?
The tag may be missing, the URL may be relative, or the file may return an error. Check why your OG image isn't showing when the file itself is the problem. Tiny images are often a poor fit for a link card. Some sites block automated requests. Tags added only by JavaScript are not visible here or to most social crawlers. Facebook and LinkedIn also cache previews, so a fix on your site can take time to replace the old card.
What is og:title?
og:title is the headline suggested for a shared link. Write it for a person scanning a feed, not as a dump of keywords. If the tag is missing, platforms often fall back to the HTML title element.
What is og:description?
og:description is the short summary suggested under the headline. One or two plain sentences work better than a full paragraph. If the tag is missing, the meta description is a common fallback.
What OG image size should I use?
1200 by 630 pixels is the OG image size most often used for a large Open Graph image. Serve it from a fully qualified HTTPS URL. Most platforms and browsers broadly support JPG, PNG, and WebP. This checker only displays the dimensions when it can detect them, and it flags any image with a side below 200 pixels.
Does this tool store my URLs?
No account or search history exists. A successful result may stay in server memory for about 10 minutes so a repeated check does not fetch the same page again. That cache is not a permanent log, and it disappears when the process restarts.
How do I check the OG tags of a website?
Paste the OG website URL above and press Preview. The OG checker reads the Open Graph and Twitter tags from the public HTML and shows how the link will look when shared.
What's the difference between an OG checker and an OG debugger?
They're the same kind of tool. An OG checker shows which tags a page has, and an OG debugger helps you find and fix missing or broken ones. This tool does both.
Can I use this OG debugger for Facebook and LinkedIn?
Yes. It estimates their previews from fresh HTML. To clear a cached card, use Facebook's Sharing Debugger or LinkedIn's Post Inspector after fixing your tags.
