Tips for the Best Result

  • Keep Lock Aspect Ratio on so photos don't look stretched.
  • Use Smart Crop with social sizes — it trims the edges instead of squashing the picture.
  • Need a file under a certain KB? Resize first, then use Compress Image to a Size.
  • Making pictures bigger than the original can look soft — for that, try Image Upscaler.
  • For websites, 1200–1920 px wide is usually plenty.

Frequently Asked Questions

Quick answers about Image Resizer.

Upload it, choose Custom, type the width and height and click Process. Turn off Lock Aspect Ratio if you need both numbers exactly.

Choose Social and pick a preset: Instagram post (1:1), story/reels (9:16), YouTube thumbnail (16:9), Facebook/LinkedIn post or WhatsApp DP.
