About the Social Media Image Sizes 2026

Every social platform updates its image and video specs without telling anyone — the dimensions you used six months ago might be cropped or down-sampled today. This guide covers the current 2026 specs for every major platform: feed posts, stories, reels, profile photos, banners, cover images, ad units, and thumbnails. Each entry shows pixel dimensions and aspect ratio so you can resize once and ship to every platform without guessing.

Common use cases

Why client-side?

Every byte you paste, type, or upload here is processed entirely inside your browser. Nothing is sent to a server, logged, or stored. That means it's safe to use this tool on production secrets, customer data, internal logs, and any input you would not paste into a hosted SaaS formatter.
