About this tool
The Open Graph image is the picture shown when a link to your page is shared on Facebook, LinkedIn, Slack, WhatsApp, X and many other apps. At 1200 by 630 pixels (1.91:1), one image covers almost all of them - it is set with an og:image meta tag in your page's HTML. Cropping here produces that 1.91:1 frame, and one export covers the link previews on Facebook, LinkedIn, X, Slack and WhatsApp, which all read the same Open Graph tag.
How to use this tool
- Add your share imageUse a branded graphic or a strong photo that represents the page.
- Keep text away from the edgesSome apps trim the preview slightly, so centre the title and logo.
- Set the og:image tagUpload the file to your site and reference it in the page’s og:image meta tag.
Making link previews look right
- Create the image at 1200 x 630 and keep text inside a central area, since some apps crop to square.
- Use an absolute https URL in the og:image tag.
- Keep the file reasonably small so previews load quickly.
- After changing it, re-scrape the URL with each platform's debugger tool, because previews are cached.
