A practical guide

Use Social Resizer with confidence

Adapts photos to the exact aspect ratios and pixel dimensions enforced by major social media networks, preventing clumsy automatic cropping and blurry platform recompression.

When this tool is useful

Instagram posts (4:5 portrait & 1:1 square), Instagram Stories (9:16), YouTube thumbnails (16:9), and LinkedIn banners.

What to check before downloading

Keep faces and text centered within the safe zone so platform interface overlays do not cover them.

A simple workflow

  1. Choose a photo to adapt for social media.
  2. Select the target platform and post preset.
  3. Position the crop box over your subject and download the ready-to-post image.

Common questions

What is the best Instagram post size in 2026?
