How to use the social media image resizer.

- Click Resize image and download each version.
Why exact image sizes matter
Every platform crops images to its own shape. An image made for a square Instagram post will be cut awkwardly in a 9:16 Story or a wide LinkedIn banner. Exporting the exact size for each placement keeps faces, products and text where you put them.
Platforms also compress uploads. Starting from the recommended dimensions means less resizing on their side and a sharper result. Keep key text inside the central safe area, especially for Stories and Reels, where interface buttons cover the top and bottom.
