Why Exact Dimensions Matter
Every social platform re-compresses images that are the wrong size. Upload an oversized photo to Instagram and it will resize and re-encode it — introducing blur and compression artifacts. Upload at the exact recommended dimensions and your image arrives pixel-perfect.

Avoid Double Compression
Upload images at exactly the right dimensions — not larger. Platforms scale down oversized images, which means your image gets compressed twice: once by you, once by the platform. Always optimise at the target dimension.
