Open Graph Image Generator (1200×630 for Every Platform)
Create the 1200×630 og:image every social platform reads. AI-generated, in-browser, and shaped for Facebook, LinkedIn, iMessage, Slack, and X unfurl previews.
Every link-preview card — Facebook, LinkedIn, Slack, iMessage, X — reads the same og:image tag. Get the 1200×630 image right once and every share of that URL looks intentional. Get it wrong and platforms substitute a random cropped screenshot.
Anatomy of a good og:image
- Exactly 1200×630 pixels (1.91:1). Anything else is cropped by at least one platform.
- Text stays inside the middle 90% — some clients pad the edges.
- High contrast between text and background; previews render small on mobile.
- Under 1 MB so slow crawlers don't time out.
Generate one in the AI thumbnail tool
- Pick the Open Graph 1200×630 preset.
- Upload your logo or a hero screenshot as reference.
- Prompt with page purpose, not decoration: "pricing page for image tools, orange accent, headline: Free forever."
- Export and drop the URL into your <meta property="og:image"> tag.
