Free Open Graph Generator
When someone shares your link, the preview is your first impression. NToolHub's free Open Graph Generator creates the og: meta tags that control how your pages look on Facebook, LinkedIn, Slack, Discord and WhatsApp. Content creators and marketers use it to make every share look deliberate and on-brand.
How to Use the Open Graph Generator
- Enter the title and description people will see when your page is shared.
- Add the canonical URL and a 1200×630 share image.
- Click Generate Open Graph Tags.
- Paste the tags into your page <head> and test with a link debugger.
Features
Build og:title, og:type, og:description, og:url, og:site_name, og:image (with alt) and og:locale tags from a guided form. The tool handles character escaping and outputs clean, copy-ready HTML with download support.
Benefits & Use Cases
Rich link previews with compelling titles and images dramatically outperform bare URLs — more clicks, more shares, more traffic. Consistent OG tags also prevent platforms from grabbing random images or truncated text.
Tips
Use a 1200×630px image under 1MB for og:image, keep titles under 60 characters, and test every page with Facebook's Sharing Debugger to clear cached previews after changes.
Frequently Asked Questions
What are Open Graph tags?
Open Graph is a protocol (originally from Facebook) of meta tags that tell social platforms which title, description and image to show when your URL is shared.
What size should my og:image be?
1200×630 pixels is the recommended size for large previews across Facebook and LinkedIn. Keep it under 1MB and use an absolute URL.
Why is the wrong image showing when I share?
Platforms cache link previews. After fixing your tags, use Facebook's Sharing Debugger or LinkedIn's Post Inspector to scrape the URL again and refresh the cache.
Do Open Graph tags affect Google rankings?
Not directly — they're for social platforms. But better-looking shares earn more clicks and links, which indirectly supports SEO.
