Frequently asked questions
What size is an Instagram post?
Square is 1080×1080 (1:1); portrait is 1080×1350 (4:5), which takes up the most space in the feed. This tool exports both directly.
Can I make carousel covers with it?
Yes. A 4:5 cover with a big headline grabs the most attention; keep the same theme across the following slides for a consistent set.
Do exports have a watermark?
No. Every image Poster Cat exports is clean and watermark-free — that's the main difference from membership tools.
