Open Graph Tag Generator
Open Graph Tag Generator creates og:title, og:description, og:url, and og:image meta elements from manual fields. It escapes HTML-sensitive text but does not validate absolute URLs, image dimensions or accessibility, fetch assets, add required og:type, infer site name or locale, create image alt/type/size tags, or preview any social network. Empty inputs produce empty content attributes.
Runs locally — files stay on your deviceIs the generated set a complete Open Graph implementation?
No. It is a minimal four-tag starting point.
Social metadata is consumed by external crawlers
Platforms fetch page markup and images under their own cache, size, content, and policy rules. Correct tags do not guarantee a particular rendering.
How it works
Four entered strings are escaped and inserted into fixed property meta templates.
Key concepts
Object URL versus page canonical
og:url should identify the shared object consistently.
Image accessibility metadata absent
No og:image:alt line is generated.
When to use it
- Draft core sharing fields.
- Create markup for a simple static page.
- Review title, description, canonical object URL, and image URL together.
When not to use it
- Do not skip platform image requirements.
- Do not assume URLs are checked.
- Do not expect cache refresh or preview.
Worked examples
Article share
- Input
Four complete fields- Expected output
Four meta tags
og:type is still absent.
Relative image

The tool does not reject it.
Common mistakes
Using a tiny image
Dimensions are not inspected. Correction: Follow destination platform guidance.
Missing image alt
Generator omits it. Correction: Add suitable og:image:alt where supported.
Expecting instant updates
Platforms cache metadata. Correction: Use platform debugging/refresh tools.
Best practices
- Use absolute HTTPS URLs.
- Provide a representative, crawlable image.
- Test deployed source with destination tools.
