Tired of cropping per platform?
The composer fits the image for you
An image outside a platform's ratio is padded with a blurred copy of itself — no white bars, no export per platform. The sizes on this page are the ones it fits to.
Media fitted per platform
An image outside a platform's ratio is padded with a blurred copy of itself. Carousels where allowed, a PDF as a LinkedIn document.

One caption; each platform gets its own card with its real limit, a title where one is needed, a first comment where the platform allows it.
Schedule, queue, or repeat
Pick a time, drop it in recurring slots, or recycle a post every few weeks. Best times to post come from your own history.
