Frequently Asked Questions
An OG image is the visual preview that appears when you share a link on social platforms like Facebook, LinkedIn, Twitter, and messaging apps. It helps attract clicks and gives a professional first impression of your content.
Custom cards increase engagement, improve brand recognition, and make your content stand out in crowded feeds. Without a proper OG image, platforms use random or generic thumbnails, which can hurt click-through rates.
Facebook/LinkedIn prefers 1200×630 pixels (1.91:1 ratio). Twitter/X cards work best at 1200×675. Instagram square posts are 1080×1080. This generator offers all three popular dimensions.
