One tool, three jobs
Everything you need to check your Open Graph tags
Sharing a link is the cheapest marketing you will ever do — if the preview looks right. The checker covers the whole job: tags, image and cross-platform rendering.
OG Image Checker
Go beyond tag presence: we load your actual og:image, measure its dimensions, weigh its file size and flag the mistakes that make WhatsApp drop previews or X shrink them to a thumbnail.
Open Graph Tester
See live link previews for all 8 platforms — X, Facebook, LinkedIn, WhatsApp, Discord, Slack, Telegram and Reddit — side by side, without opening eight apps.

How to check your Open Graph tags
1
Paste your URL
Enter any public page — your homepage, a blog post, a product page. No signup, no limits, nothing to install.
2
We fetch and audit it
The checker loads your page exactly like a social platform would, parses your og:* and twitter:* tags and inspects the real image behind og:image.
3
Fix what the score flags
Read the 0–100 score, preview all eight platforms, then fix the flagged issues — or regenerate a compliant image with the free generator.
Beyond OG tags: audit every tag in your head with theMeta Tag Checker, or validate every URL in your sitemap with the Sitemap Validator.
FAQ
Frequently asked questions
What is an OG image checker?
An OG image checker is a free tool that inspects the Open Graph metadata on a webpage and shows how that link will appear when shared on social platforms. Paste a URL and it reads your og:title, og:description and og:image tags, then renders live previews for X, Facebook, LinkedIn, WhatsApp, Discord, Slack, Telegram and Reddit.
What is the ideal OG image size?
1200 × 630 pixels for X, Facebook and LinkedIn (LinkedIn crops to 1200 × 627). Use JPG or PNG, keep the file under 5 MB, and keep it under 300 KB for WhatsApp — larger files are often dropped entirely.
Why is my OG image not showing?
Four most common causes: og:image missing from the <head>, the image URL is relative instead of absolute, the file exceeds the platform limit, or the platform cached the old preview. Most platforms cache aggressively — re-run their debugger after fixing.
How do I fix missing Open Graph tags?
Add og:title, og:description, og:image and og:url meta tags to the <head> of every page you want shareable. The image URL must be absolute (starting with https://). Re-check after deploying.
How do I test Open Graph tags?
Paste your live URL into the checker above — it audits every tag, renders 8 platform previews and scores the page in one pass. The Facebook Sharing Debugger and the X Card Validator remain useful for forcing a cache refresh, but for an everyday audit this is the faster loop. Testing a live URL (not a local file) is essential — platforms fetch the deployed page.
What is the difference between Open Graph and Twitter Cards?
Open Graph (og:*) is what Facebook, LinkedIn, WhatsApp, Discord, Slack, Telegram and Reddit read. Twitter Cards (twitter:*) apply to X only. Under summary_large_image, X falls back to og:* when twitter:image is absent — correct Open Graph tags cover both.
Does WhatsApp support Open Graph images?
Yes, but stricter: keep the image under 300 KB and use a direct, publicly accessible URL, or the preview shows text only. You can check exactly how your link will look in WhatsApp before posting — paste the URL above and the WhatsApp preview renders with a warning if the file would be dropped.
Is ogimagechecker.com free to use?
Yes — entirely free, no signup, no credit card. The checker, generator, meta tag auditor, sitemap validator and the REST API (10 requests/hour, no key) all work without an account.
