Generate an OG image

Type a title, pick a ratio, download the PNG. That's the whole tool.

What's rendering it

This is not a canvas mockup. Every preview is a live render from turbo-start-sanity (opens in new tab)'s OG route, the same ImageResponse code the template ships, running on this site's edge runtime with a year-long immutable cache in front of it. The card you download is pixel-identical to what a site built on the template serves to crawlers.

The three sizes cover the jobs that matter: 1200x630 for link unfurls everywhere (X, LinkedIn, Slack, iMessage), 1080x1080 for square feed posts, and 1080x1350 for Instagram portrait.

Want it automated instead

Downloading PNGs one at a time is fine for a landing page. For a site, wire the route in so every page gets its card generated on demand. The code is MIT-licensed in the turbo-start-sanity repo (opens in new tab), and Never "design" an OG again walks through extending this exact template to render every aspect ratio from one design, with real benchmarks and the production failure modes.

If you'd rather someone else wire it up, that's what we do.

Common questions

FAQs

What people ask before picking up OG image generator

Is it really free, and is there a watermark?
Free, no watermark and no sign-up. Type a title, pick a ratio, download the PNG.
Is the preview a mockup of what my site would produce?
No, it is the real thing. Every preview is a live render from turbo-start-sanity's OG route, the same ImageResponse code the template ships, running on this site's edge runtime. The card you download is pixel-identical to what a site built on the template serves to crawlers.
Which sizes does it produce and what are they for?
1200x630 for link unfurls everywhere (X, LinkedIn, Slack, iMessage), 1080x1080 for square feed posts, and 1080x1350 for Instagram portrait.
Do I need a Sanity site to use the generator?
No. The generator is just a page on this site that renders a PNG you download, so it works whatever your stack is. Sanity only comes into it if you want the automated version, since the template the route comes from is a Sanity and Next.js starter.
Can I generate these automatically instead of one at a time?
Yes, and for a whole site you should. Wire the route in so every page gets its card on demand. The code is MIT-licensed in the turbo-start-sanity repo, and our post 'Never design an OG again' walks through extending this template to render every aspect ratio from one design, with benchmarks and the production failure modes.
