What size should an Open Graph image be?

1200 × 630 pixels is the safe default for LinkedIn, Facebook and X large cards. Keep important content in the centre, because some placements crop the edges.

Why is LinkedIn showing an old image?

LinkedIn caches link previews. Run the URL through LinkedIn’s Post Inspector to fetch it again after you update your tags.

Do I need Twitter tags if I have Open Graph tags?

X falls back to Open Graph tags for title, description and image. Adding twitter:card set to summary_large_image makes sure it uses the large layout.

Does this tool fetch my live page?

No. It only uses what you type, and your browser loads the image URL directly. Nothing is sent to me.

Open Graph preview

Enter a page title, description and image URL to see roughly how your link will look when it is shared on LinkedIn, Facebook and X. Then copy the Open Graph and Twitter tags into your page.

How to use it

Paste your page URL, title and a short description.
Paste the full URL of a 1200 × 630 image. It loads in your own browser.
Check all three previews and shorten anything that looks cramped.
Copy the meta tags into your page’s head.

Why it matters

Every time someone shares your site, the platform builds a little card from your Open Graph tags. Without them, it guesses, and it usually guesses badly: the wrong image, a cookie notice as the description, or no card at all.

For a service business this card is often the first impression in a referral. A partner shares your site in a LinkedIn post or a group chat, and the card is what people see before they click.

The image does most of the work. Use 1200 × 630 pixels, keep text away from the edges, and make sure it still reads when shown small.

Good to know

Use absolute URLs
og:image must be a full URL starting with https://. Relative paths often fail.
Clear the cache
Platforms cache cards. After changing tags, use LinkedIn’s Post Inspector or Facebook’s Sharing Debugger to refresh them.
Previews are approximate
Each platform changes its layout from time to time. These previews show proportions and cropping, not pixel-perfect copies.
