Open Graph Generator

Builds the Open Graph tags that control how your link looks when shared, with a live card preview.

Runs in your browser. The file or text you give it is not uploaded. Free, no account.

How it works

You have a page to share and no control over how the link looks. This tool writes the Open Graph tags behind the card: title, description, address and image. Paste an image address and it loads the file to read the real size, then flags dimensions that may prevent a large card. The platform still decides what appears.

  1. 1

    Enter the title, description, address and image. The card preview updates as you type.

  2. 2

    Paste an image address and the tool loads it to read its real size, then flags dimensions against common large-card guidelines; the platform decides the final layout.

  3. 3

    The output includes image dimensions and alt text; the receiving platform controls the final card.

What it does not do

  • The image must be at a public address the platforms can fetch.

  • After changing tags on a page that was already shared, platforms keep the old card until their cache is refreshed.

When a source is busy or a site does not answer, this tool says so. It never fills the gap with a guess.

Questions

I shared a link and the card is still the old one. Why?

Platforms cache the card for a page. After you change the Open Graph tags, the platform keeps showing the old card until its cache is refreshed. Nothing in the page markup forces that refresh. Check your image address first, because the image must be at a public address the platform can fetch.

What image size do I need for the large card?

Paste the image address and the tool loads the file and reads its real dimensions, then flags dimensions against common large-card guidelines. This is not a guarantee of the platform's layout. The output includes dimension and alt tags. Small or inaccessible images can prevent a large card; tags do not guarantee its appearance.

Do I still need a meta description if I have Open Graph tags?

They do different jobs. Search engines read the meta description for the result snippet; platforms read the Open Graph tags for the shared card. Leaving out the Open Graph tags means the platform picks whatever it finds on the page, usually the title and the first text it can read.
