Open Graph Image Checker

The Open Graph Image Checker generates a live Bootstrap 5 preview card that simulates how your URL will appear when shared on Facebook, Twitter/X, LinkedIn, and other OG-aware platforms. Paste in your meta values and see the rendered social card instantly — no browser extension or third-party API required. Built for developers, SEO engineers, and marketers who need to validate og:image, og:title, and og:description before pushing to production.

How to Use

1. Configure your Open Graph metadata — enter the page title, description, image URL, site name, and canonical URL in the Content fields. 2. Adjust the design settings: choose which platform preview to simulate (Facebook, Twitter Card, LinkedIn), set the card theme, accent color, and image aspect ratio. 3. Preview the rendered social share card instantly in the output panel — it updates live as you edit. 4. Copy or download the generated Bootstrap 5 HTML to embed the preview mockup in documentation, client reports, or internal QA checklists.

Why Use This Tool?

Debugging Open Graph tags normally means pushing to staging and using Facebook's Debugger or Twitter's Card Validator — both require a live URL and a round-trip network request. This tool renders the social card locally with zero dependencies, saving 5–10 minutes per iteration cycle and letting you validate metadata during local development before any deployment. Because the output is plain Bootstrap 5 HTML, you can drop it directly into reports, Confluence docs, or CI preview pages without installing anything.

Frequently Asked Questions

What is the Open Graph Image Checker?
It's a client-side tool that renders a visual simulation of your Open Graph / social share card — showing exactly how your og:title, og:description, og:image, and og:url will display when a page is shared on Facebook, LinkedIn, Twitter/X, or iMessage.
What image dimensions should I use for og:image to pass validation on all platforms?
The safest universal size is 1200×630 pixels (1.91:1 ratio), which satisfies Facebook, LinkedIn, and Twitter/X simultaneously. Twitter's Summary Card with Large Image crops to roughly 2:1, so keep critical content within a 1200×600 safe zone. Images must be at least 200×200 px to render on Facebook at all, and files should be under 8 MB (Facebook) or 5 MB (Twitter). Use HTTPS URLs — mixed-content images will silently fail on most crawlers. PNG is preferred for graphics with text; JPEG for photographs to keep file size under the recommended 300 KB for fast unfurl load times.
Is it free?
Yes — the Open Graph Image Checker is completely free with no signup required. Built by the CanvasBuilder.co team.
