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.

|---|---|---|

**Tip**: Instagram shows posts in a grid at 293×293px on desktop. Use high contrast in the top portion of your images for best thumbnail impact.

YouTube Image Sizes 2026

|---|---|

**Tip**: YouTube thumbnails display at 320×180px in search results. Make sure text and key visuals are clearly visible at small sizes.

How to Resize for Any Platform

Upload your image

Enter the exact pixel dimensions for your target platform

Optionally maintain aspect ratio or crop to fit

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.
