FAQ
What is an OG image?
An Open Graph image is the preview picture that appears when a link is shared on social media, WhatsApp, Slack, or iMessage. Links with a good OG image get far more clicks.
What size are the images?
Every image is 1200×630 — the standard Open Graph size that every major platform reads.
Can I generate them dynamically?
Yes. Build the URL with your title and subtitle at request time, set it as og:image, and a fresh card is generated automatically per page.
Do I still need a designer?
No. Pick a theme and accent color once, then every post and product gets a consistent, on-brand card with zero manual work.
