Crop and placement check
Check the destination frame before export. Cropping fills the placement; padding or letterboxing preserves the complete source.

Square dimensions are useful when the same image needs to work as a profile image, icon, thumbnail, product card, or feed post. Keep the subject centered and leave enough padding for circular crops.
Frequently asked questions
What does 1:1 mean?
A 1:1 ratio means the width and height are the same.
Is 1080 × 1080 a good square size?
Yes. It is a common high-quality square export size for social feeds.
Can any square size be 1:1?
Yes. 500 × 500, 1024 × 1024, and 2000 × 2000 are all 1:1.
