Useful before you publish

Prepare a post at the right aspect ratio, preserve a key subject in a crop, or make a consistent set of images for a content plan.

Prepare a 3:4 photo at 1080 × 1440, or use 4:5 portrait for designs created around that established feed ratio.
Prepare a 9:16 Story image while reviewing the final framing on a smaller screen.
Export a clean JPEG, PNG or WebP file at the exact dimensions you need for your publishing workflow.
