OG Image Checker & Open Graph Preview

An Open Graph checker is a free tool that inspects the Open Graph metadata on a webpage and shows you how the link may appear when shared. It checks tags such as og:title, og:description and og:image, then previews your link across platforms including Facebook, X/Twitter, LinkedIn, WhatsApp, Slack and Discord. It can also highlight missing metadata, image problems and other issues that could affect your social preview.

An OG image checker focuses specifically on the image used in your social link preview. It checks your og:image tag, verifies that the image can be accessed, checks its dimensions and displays previews for platforms such as Facebook, X/Twitter, LinkedIn, WhatsApp, Slack and Discord so you can spot image, sizing or cropping problems before sharing.

Enter your webpage URL into our Open Graph checker to inspect the metadata used to create your social link preview. You can check og:title, og:description, og:image and other Open Graph tags, then see how that information may be displayed on Facebook, LinkedIn, X/Twitter, WhatsApp, Slack and Discord.

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.

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 1 MB, and under about 300 KB if you care about WhatsApp.

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 1 MB (under 300 KB if you care about WhatsApp), 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.
