Paste your page source and preview how your link looks on Facebook, X, WhatsApp and Google. Check your Open Graph tags. Free.
Used to complete picture links that do not start with https://.
Browsers do not let one website read another website’s page, so this tool cannot fetch the address for you. It also means your page is never sent anywhere.
NinjaFunction's Open Graph Preview Checker shows how your link will look when shared. Paste your page source or head tags and see close previews for Facebook and LinkedIn, X (Twitter), WhatsApp and Google. A check list reviews og:title, og:description, og:image, og:url and twitter:card, loads your picture to check its size and shape, and lists every tag it found. Your page is read in your browser and never uploaded.
| Tag | What it controls | Good value |
|---|---|---|
| og:title | The headline of the card | 40 to 60 characters |
| og:description | The text under the headline | 60 to 160 characters |
| og:image | The picture on the card | Full https address, 1200 × 630 pixels |
| og:url | The main address of the page | The same as the canonical link |
| twitter:card | The card style on X | summary_large_image |
Open Graph is a set of meta tags in the head of a web page, such as og:title, og:description and og:image. Facebook, LinkedIn, WhatsApp and many other apps read them to build the card that appears when someone shares your link.
Browsers do not let one website read another website’s pages, so a tool that runs in your browser cannot fetch your address. Pasting the source also keeps your page private, because nothing is sent to a server. Right-click your page, choose View page source and copy it.
Use 1200 × 630 pixels, which is a shape of about 1.91 to 1. Keep it under 5 MB, and use JPG or PNG. Facebook ignores pictures smaller than 200 × 200, and small pictures look blurry or get cropped.
X falls back to your Open Graph tags for the title, description and picture. The one tag worth adding is twitter:card with the value summary_large_image, which gives you the large picture card.
Platforms keep a copy of each link for a while. Use the official debugging tools from Facebook, LinkedIn and X to refresh them. This tool shows your current tags, not the saved copy.
It is a close copy, built from the tags the platforms read. Each app can change its design and where it cuts off long text, so use this to catch problems and as a guide.
The tool loads your og:image in your browser and reports its size and shape. It warns about small pictures, wrong shapes that will be cropped, addresses that are not complete, and pictures that cannot be loaded.
No. Everything is read inside your browser. Only the picture is requested from its own address, so your browser can show it.
