Open Graph Meta Tags Generator

Write the meta tags every social platform reads when your page is shared. Fill in the fields, copy the HTML, paste it into your page's <head>. Free, no signup, nothing uploaded.

Recommended: under 60 characters (it is also your <title>).

Recommended: 50–160 characters. Also emitted as the standard meta name="description".

1200×630 recommended.

Tip: paste a URL and hit the button below to copy the tags — the page reloads with your values pre-filled, which also makes the output shareable.

Your meta tags

Paste into the <head> of your page, deploy, then re-scrape with Facebook's Sharing Debugger or the X Card Validator. If your image changes often, let FastOG generate it dynamically.

Frequently asked questions

What is an Open Graph meta tag generator?

An Open Graph meta tag generator is a tool that writes the meta tags social platforms read when your page is shared. It produces copy-paste HTML for og:title, og:description, og:image and og:url, plus the matching Twitter Card tags, so your links show a proper preview on Facebook, LinkedIn, WhatsApp, X and Slack.

What is the difference between Open Graph and Twitter Card tags?

Open Graph tags (og:*) are read by Facebook, LinkedIn, WhatsApp and most other platforms. Twitter Card tags (twitter:*) let X override the same fields with its own format. They cover the same information, so this generator outputs both — it is harmless to include them together.

Why is my og:image not showing on Facebook or X?

Most often because the image URL is not public, the image is larger than 8 MB, or the platform cached an old version. Upload the image to a public URL first, then re-scrape with Facebook's Sharing Debugger or the X Card Validator. If your image changes often, use a dynamic Open Graph image API like FastOG instead of re-uploading every time.

What size should my Open Graph image be?

1200 x 630 pixels is the recommended size for og:image — it scales to most timelines and chat previews. Keep the file under 8 MB and use a widely supported format such as PNG or JPG.

Do I need a separate Open Graph image generator?

Only if your image changes. This tool generates the meta tags; FastOG generates the og:image itself — a dynamic image rendered from your title and text every time, signed and served from a single URL. That is what the FastOG API is for.

Is FastOG's meta tag generator free?

Yes. This generator is free, requires no signup, and runs entirely in your browser — nothing is uploaded or stored. You can copy the output straight into the head of your page.
