Open Graph Checker & OG Tag Tester

Check your Open Graph tags, preview link cards for Facebook, X, LinkedIn, and WhatsApp, and generate corrected meta tags in seconds.

How to use & benefits of Open Graph Checker

When a link is shared on Facebook, X (Twitter), LinkedIn, or WhatsApp, the platform reads the page's Open Graph (OG) meta tags to build the link card — the image, title, and description people actually see. If those tags are missing, malformed, or point to a broken image, your link shows up as a bare URL or a blank card, and click-through rates collapse.

This Open Graph checker lets you test your og:title, og:description, and og:image tags and see a pixel-accurate preview of how your link will render on each major platform — before you publish. Pages with a correct OG image consistently earn significantly more clicks than bare links, so a thirty-second check here pays for itself on every post you share.

Why OG Tags Break (and How This Tool Helps)

The most common failures are an og:image URL that is relative instead of absolute, an image that is too large or in an unsupported format, missing og:url canonical values, and stale platform caches showing an old preview. This og tag tester surfaces each of these problems visually: if the image slot renders empty in the preview, you know exactly what your audience would see. Generate the corrected meta tag block, paste it into your page's <head>, and re-test until every platform card looks right.

Works for Every Platform

Facebook and WhatsApp read standard og:* properties, while X (Twitter) prefers twitter:card tags and falls back to Open Graph. LinkedIn uses OG tags with its own image-ratio crop. This checker previews all four side by side so you never have to guess how a card will be cropped or truncated on a specific network.

Frequently Asked Questions (FAQ)

What is an Open Graph checker?▼

An Open Graph checker is a tool that tests the OG meta tags on a web page and shows a preview of how the link will look when shared on social platforms like Facebook, X (Twitter), LinkedIn, and WhatsApp. It helps you catch missing images, wrong titles, and truncated descriptions before you share a link publicly.

Why is my og:image not showing on WhatsApp or Facebook?▼

The most common causes are: the og:image URL is relative instead of absolute (it must start with https://), the image file is too large (keep it under 5 MB, ideally under 1 MB), the image is behind a redirect or blocked by robots.txt, or the platform has cached an old version of your page. Test the tags with this checker, then use Facebook's Sharing Debugger to force a re-scrape.

What size should my og:image be?▼

Use 1200 × 630 pixels (1.91:1 ratio). This renders sharply on Facebook, X large-card previews, LinkedIn, and WhatsApp. Keep the file under 1 MB and use JPG, PNG, or WebP format.

How do I refresh the cached preview after fixing my tags?▼

Each platform caches link previews. Use Facebook Sharing Debugger ("Scrape Again") for Facebook and WhatsApp, LinkedIn Post Inspector for LinkedIn, and the Card Validator behavior on X. After re-scraping, the new preview appears.

Do X (Twitter) cards use Open Graph tags?▼

Partially. X prefers its own twitter:card, twitter:title, and twitter:image tags, but falls back to Open Graph tags when those are absent. For best results, include both sets — this tool generates them together.

Is this OG tag tester free?▼

Yes — completely free, no account needed, and no usage limits. The check runs in your browser and your URLs are not stored.
