How to Use the Open Graph Generator
If you’ve never generated OG tags before, the workflow takes about sixty seconds. Follow these five steps and you’ll have valid, share-ready meta tags in your site’s <head>.
- Fill in the form fields. The required inputs are
og:title,og:url, andog:image. Optional fields likeog:description,og:type, andog:site_nameimprove click-through rates on Facebook, LinkedIn, and Slack. - Watch the live preview update. Switch between the Facebook and Twitter tabs to see exactly how your link card will render on each platform. The image, title, description, and domain update on every keystroke.
- Read the validation panel. Each check turns green when it passes, amber when it’s a soft warning, and red when it blocks publication. The validator checks for absolute URLs, recommended character counts, and missing required fields.
- Copy or download the HTML. Click “Copy HTML” to drop the generated tags on your clipboard, or “Download .html” to save a starter file you can open in any editor.
- Paste the tags into your page. Drop the generated
<meta>tags into the<head>section of your HTML, just above the closing</head>tag. Re-test with the Facebook Sharing Debugger and the Twitter Card Validator to confirm the live fetch.
Understanding Open Graph Tags and Formats
Open Graph is a protocol originally published by Facebook in 2010 that turns any web page into a rich object in a social graph. Twitter’s equivalent is called Twitter Cards. Both rely on <meta> tags in your HTML <head>, and both work without any JavaScript. Below are the tags this open graph generator produces, the recommended values, and the platforms that read them.
| Tag | Recommended value | Used by |
|---|---|---|
og:title | ≤ 60 chars (FB) / ≤ 70 (X) | Facebook, LinkedIn, Slack, Discord, iMessage |
og:description | ≤ 155 chars (FB) / ≤ 200 (X) | Facebook, LinkedIn, Slack, Discord |
og:url | Absolute canonical URL | All platforms |
og:image | 1200×630 px, < 8 MB | All platforms |
og:type | website, article, product | Facebook, LinkedIn |
og:site_name | Brand name (≤ 60 chars) | Facebook, LinkedIn |
og:locale | en_US, ar_SA, … | Facebook, LinkedIn |
twitter:card | summary_large_image (default) | Twitter / X |
twitter:site | @yourhandle | Twitter / X |
twitter:title / twitter:description / twitter:image | Override OG only when X needs different copy | Twitter / X |
The generator also accepts the article-specific extensions article:published_time, article:author, and article:section on the underlying schema — they round-trip through the same preview. If a platform doesn’t recognise a tag, it silently ignores it, so it’s safe to publish all of them and let the crawlers pick what they need.
Why Choose This Open Graph Generator
There are dozens of OG tag tools online. Here’s what makes this the best open graph generator for marketers and developers in 2026 — and why the team at ToolNova uses it ourselves.
Live, Frame-Accurate Preview
Watch the Facebook and Twitter share cards update on every keystroke. No “Generate” button, no waiting — see exactly how the link will look before you publish.
100% Private & Local
All form data and previews run in your browser. URLs, titles, and images never touch a server, a log, or a third-party analytics tool. Safe for client work and confidential pages.
Built-In Validation
Five live checks flag missing fields, weak character counts, and non-absolute URLs before you copy. The image-dimension check runs after the image loads, so you catch aspect-ratio mistakes at the source.
One-Click Copy & Download
Copy the generated HTML to your clipboard, or download a starter .html file. Both outputs include syntax-coloured, indentation-clean meta tags ready to paste.
Light & Dark Modes
The interface follows your system theme automatically. Late-night launch prep stays easy on the eyes without a manual toggle.
WCAG 2.2 AA Accessible
Full keyboard navigation, ARIA live regions, visible focus rings, and 4.5:1 contrast across every input, button, and validation row. Screen-reader tested.

Privacy & Security: What Leaves Your Browser
Most online generators ship your page URL, title, and image to a backend for “validation” and analytics. This one doesn’t. Every keystroke, every preview update, and every validation check runs locally in your browser using the same JavaScript engine that powers your email client. Nothing is logged, cached, or transmitted by the generator itself.
Image() when the host allows it. Cross-origin images without CORS headers are flagged but never proxied through a third party.If you’re working on confidential material — unreleased product launches, embargoed PR pages, internal dashboards — this free open graph generator online is one of the few tools safe to use without a privacy review.
Frequently Asked Questions
Is this open graph generator really free?
Yes — completely free, with no sign-up, no usage cap, and no hidden premium tier. You can generate as many OG tag sets as you like, on as many devices as you like. The page is supported by unobtrusive display ads; you never pay a cent.
What image size should I use for og:image?
For Facebook and LinkedIn, the recommended size is 1200 × 630 pixels with a 1.91:1 aspect ratio. For Twitter’s summary_large_image card, 1200 × 675 (or any 2:1 image) works. The validator will accept anything larger and warn on anything smaller than 600 × 315. Keep the file under 8 MB for fastest rendering on slow networks.
Do I need both og: and twitter: tags?
Yes — Twitter / X still reads its own twitter:card, twitter:title, and twitter:image tags and falls back to OG tags only when they’re missing. Publishing both gives you full coverage across Facebook, LinkedIn, Slack, Discord, iMessage, and X. This open graph generator emits both by default.
How do I test the tags after I publish them?
Use the Facebook Sharing Debugger and the Twitter Card Validator to re-scrape your page and confirm the live share card. Both tools show exactly which tags the platform read and warn about anything malformed. Remember that social platforms cache aggressively — re-validate 24–48 hours after a tag change.
Can I use this on my phone?
The generator is fully responsive and works on iOS 16+ and Android 9+. The form reflows into a single column on narrow screens, the preview cards scale to fit, and the copy / download buttons stay reachable with one thumb. The image-dimension check works as long as the phone browser supports cross-origin image loads.
Final Word
A reliable open graph generator should disappear into your launch workflow — fast enough to keep up with last-minute page updates, accurate enough to match the Open Graph protocol and the Twitter Cards spec, and private enough for confidential pages. This tool was built around those three constraints: a frame-accurate live preview, a validator that catches the five mistakes that break share cards 90% of the time, and zero server-side processing of your page data. Whether you’re a marketer shipping a launch landing page, a developer wiring OG tags into a static-site build, or a blogger polishing a viral post, the output above will pass every sharing debugger on the first try.
