Open Resize Image to 1200×630Why 1200×630 is the magic number
Open Graph (og:image) spec historically pointed to 1200×630, and the big networks still favor it. Larger images get downscaled; smaller ones get upscaled into blur. 1200×630 hits the sweet spot that every major platform renders cleanly.
Build a share-ready preview
- Design your cover at 1200×630 or grab any image.
- Open the Resize Image tool and output exactly 1200×630 (or crop to 1.91:1 first with the Crop tool).
- Export as JPG at 80% — typically 100-250KB, far under the 5MB og:image cap.
- Reference the file in your site's Open Graph meta tag.
Keep text inside the safe strip
The classic 1.91:1 geometry means the visible strip is wide but short. Keep titles and logos inside the central band so none of the platforms clip them in their timeline preview.
