Open Graph Checker: Frequently Asked Questions
What is Open Graph?
Open Graph tags tell social networks which title, description and image to show when your link is shared.
What image size is best?
1200Γ630 pixels (1.91:1), JPG or PNG, under about 600 KB for fast WhatsApp previews.
Why does Facebook show an old image?
Facebook caches previews. Use Facebookβs Sharing Debugger to refresh after fixing your tags.
Do I need Twitter tags?
X reads Open Graph as a fallback, but twitter:card=summary_large_image gives the big image card.
Is this free?
Yes.
