Meta Tags & Open Graph
Generate the SEO, Open Graph and Twitter card tags for a page, ready to paste into the head.
1200 × 630 is the size every platform crops to. Use an absolute URL — a relative one is ignored.

What it does
Meta Tags & Open Graph produces its output in your browser using the platform's own cryptographic random source where randomness matters — not a seeded pseudo-random shortcut. The head block, done properly.
When you need it
Whenever you need a value that has to be correct rather than approximately right, and typing one yourself would either be predictable or a formatting mistake waiting to happen.
Limits and caveats
Nothing is generated on a server, logged, or recoverable — if you close the tab without copying the result, it is genuinely gone. Keep anything you intend to rely on in a password manager rather than in this page. Everything happens in your browser, so the file never leaves your device.
How to use the Meta Tags & Open Graph
- Set the options you want.
- Your result is generated instantly.
- Copy or download it.
Everything happens on this device: no file is uploaded and nothing leaves the browser.
Frequently asked questions
- Why both Open Graph and Twitter tags?
- They overlap but don't substitute for each other. A page with only Open Graph renders on Twitter badly; a page with only Twitter tags is bare everywhere else. Both are emitted, which is what actually works.
- How big should the preview image be?
- 1200 × 630. Every platform crops to roughly that ratio, and it must be an absolute URL — a relative path is silently ignored by every scraper.
- Why did nothing change after I updated the tags?
- Because platforms cache what they scraped. Facebook's Sharing Debugger and LinkedIn's Post Inspector both have a re-scrape button; without it you can be looking at a preview from weeks ago.
