Meta Tags & On-Page · Runs in your browser · Free
Open Graph Tag Generator
Generate Open Graph meta tags so shared links show the right title, description and image.
What this tool does
Creates og:title, og:type, og:url, og:image and related tags used by Facebook, LinkedIn, Slack, WhatsApp and many other apps when a link is pasted.
Who should use it
Anyone whose pages are shared on social platforms or messaging apps.
How it works
Each field becomes a <meta property="og:…"> tag with escaped content. The tool checks that the image URL is absolute and warns when no image is set.
How to use it
- Enter or paste og:title in the form.
- Adjust the options below the main box if you need to; the defaults suit most cases. Use "Load example" to see how input should look.
- Press the run button. Processing happens instantly in your browser.
- Review the result panel, then copy or download the output if the tool offers it. Use Reset to start over.
Practical example
A title, URL and a 1200×630 image URL produce a complete card for link previews.
Understanding the results
Warnings highlight a missing image or a relative image URL, which many platforms ignore.
Limitations
Platforms cache previews and may crop images differently. Use each platform's debugger to refresh a cached preview.
Accuracy and report transparency
Results are computed in your browser from exactly what you enter. Deterministic steps (counting, parsing, encoding, validation) are verified by an automated test-suite with known answers. Where a method is a heuristic, the result panel says "estimated". No external data is used and nothing is invented.
Privacy
Your input never leaves your device for this tool. We count anonymous events (tool opened, run, copied) without storing what you typed. See the Privacy Policy.
Frequently asked questions
What size should the image be?
A common recommendation is 1200×630 pixels with the main content in the centre, under 5 MB.
Is my data sent to your server?
No. This tool runs entirely in your browser, so the text or files you enter stay on your device. We do record anonymous counts of how often each tool is opened or run (no input data) to see which tools are useful.
How accurate are the results?
Counting, parsing, encoding and validation steps are deterministic and covered by automated tests with known answers. Anything based on a heuristic is labelled "estimated" in the result panel.
Is this tool really free?
Yes. There is no account, limit or paid plan. The site is supported by advertising, which is disclosed on our Advertising Disclosure page.
