OG Image Checker & Open Graph Preview

An OG Image checker is a free tool that inspects the Open Graph metadata on a webpage and previews how the link appears when shared on platforms including Facebook, X/Twitter, LinkedIn, WhatsApp and Discord. It checks tags such as og:title, og:description and og:image, highlights missing metadata, image problems and other issues that could affect your social preview, providing an actionable report to show how to fix the issues.

An Open Graph checker, also called an OG checker, OG tester or OG debugger, reads every Open Graph tag on a page, not just the image. That means og:title, og:description, og:url, og:type and og:image, plus the Twitter Card tags X uses. It flags tags that are missing, too long or broken, and shows an OG preview of the card each platform will build from them.

Enter your webpage URL into the checker at the top of this page. The OG test takes a few seconds. It reads og:title, og:description, og:image and the other Open Graph tags, shows an OG preview for Facebook, LinkedIn, X/Twitter, WhatsApp and Discord, and lists anything that needs fixing.

Different platforms can handle cached previews and multiple images differently. If Facebook, LinkedIn, X/Twitter, WhatsApp, Slack or Discord is showing the wrong image, check the live og:image value first and make sure it points to the image you actually want to display. You may also need to refresh the platform's cached version of the URL.

Facebook's Sharing Debugger and LinkedIn's Post Inspector each show one platform, and you need to be signed in to use them. This OG debugger needs no account and previews every platform from one scan. Use the platforms' own tools afterwards to make them fetch your page again.

Open Graph meta tags are HTML tags that tell social platforms what information to display when someone shares a webpage. They can control the page title, description, preview image, URL and other details.

An Open Graph image is the picture that appears when someone shares your page. It is set with the og:image meta tag and becomes the visual for the link preview on Facebook, LinkedIn, X, WhatsApp, Slack, Discord and elsewhere.

The preview card is the first impression of your link. A designed image gets more clicks than a missing, cropped or generic one — and you decide what people see instead of leaving each platform to guess.

1200 × 630 pixels, a 1.91:1 landscape ratio. That is the size Facebook, LinkedIn, X, Discord and Slack all design their large card layouts around. Below roughly 600 × 315 most platforms drop the large card and fall back to a small square thumbnail. Keep the file under 600 KB, Meta's limit for WhatsApp previews, and around 300 KB for headroom.

A converting Open Graph image has one clear subject, readable text at small sizes, and enough contrast to stand out in a feed. Keep logos and headlines inside a safe area about 100 pixels from each edge, and avoid a logo on a blank background or a screenshot of UI.

Yes. Without og:image, most platforms collapse the card to a thin text row — or pick a random image from the page. Every public URL you expect people to share should declare its own image.

Yes. A single branded default is far better than no image, and it is the right starting point for most sites. Per-page images are worth generating once the default is in place, particularly for articles and product pages where the specific content is the reason someone is sharing the link.

Design a 1200 × 630 image, export it under 600 KB (Meta's limit for WhatsApp previews), host it at a public HTTPS URL, and point og:image at that absolute URL. You can also start from a template on this site and download a ready PNG.

Platforms cache link previews independently and often for days. Updating the tag does not change posts that have already been shared. Confirm the new image is live with this checker, then use each platform’s own debugger to force a fresh scrape before you share the URL again.

Yes, ogimage.info is completely free to use. You can check, test and preview any URL, and improve your image with one of our free templates.
