What is an OG Image Checker?
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, LinkedIn, X (Twitter), Slack, and WhatsApp. It validates your Open Graph meta tags, Twitter Card tags, and displays the exact title, description, and preview image that will appear.
Open Graph tags are HTML meta tags created by Facebook (Meta) 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.
