Crop to the exact size
Pick the surface; each page has the size from the platform's own documentation, the date it was read, and a cropper that exports those pixels without uploading the file anywhere. The full table with sources is on social media image sizes.

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.
Write once, tailor per platform
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.
