Why this matters

Every platform has preferred image dimensions. Posting incorrect size can cause cropping, blur, or awkward framing. Resizing before upload gives cleaner visuals and lower file size.

Important facts to know first

  • WhatsApp shared media is often easiest below 5MB.
  • Instagram square baseline: 1080x1080.
  • Facebook link preview baseline: 1200x630.

Step-by-step guide

  1. Use Image Resizer.
  2. Choose target platform dimensions.
  3. Maintain aspect ratio when possible.
  4. Apply resize and review crop framing.
  5. Download and upload to platform.

Practical tips for better results

  • Export social images in JPG for smaller file size.
  • Keep key text/content away from edges to avoid auto-crop cutoffs.
  • Create platform-specific versions instead of one-size-for-all image.
