An **OG Image Checker** (Open Graph Image Checker) is a free tool that previews how your web page appears when shared on social media platforms like [Facebook](https://posteverywhere.ai/facebook-scheduler), [LinkedIn](https://posteverywhere.ai/linkedin-scheduler), [X (Twitter)](https://posteverywhere.ai/blog/how-to-schedule-posts-on-x), Slack, and WhatsApp. It validates your [Open Graph meta tags](https://ogp.me/), [Twitter Card tags](https://developer.x.com/en/docs/twitter-for-websites/cards/overview/abouts-cards), and displays the exact title, description, and preview image that will appear. Open Graph tags are HTML meta tags created by [Facebook (Meta)](https://developers.facebook.com/docs/sharing/webmasters/) that control how URLs are displayed when shared on social media. Without proper OG tags, your links may show broken images, incorrect titles, or missing descriptions, hurting click-through rates and engagement.
