FAQ
What is the recommended Open Graph image size?
1200×630px is the widely recommended size, giving a roughly 1.91:1 aspect ratio that displays well across Facebook, LinkedIn, and most link preview cards.
What happens if my image is too small?
Platforms may still display it, but it can appear stretched, cropped unpredictably, or replaced by a fallback image depending on the platform's minimum size requirements.
Does this check my actual og:image tag?
No — enter your image's dimensions directly; this doesn't fetch or read tags from a live URL.
