Resize Photos on an iPhone Without an App

Posted by Jen Tong on December 2, 2015

You took a cool photo of an awesome street vendor hot dog and you want to share it, but you’re on 3G and your phone has an 8 megapixel camera. Or worse yet, you took a panorama that’s like 60MB.

The iOS photo editor has a crop tool, but no resize tool. You could install an app to resize the image, or you could follow these easy steps:

  1. Open your awesome photo in the photos app.
  2. Take a screen shot by pressing the power and home button at the same time.
  3. Navigate to the screen shot in the photos app.
  4. Crop the iOS user interface and black bars off of the photo.
  5. Share your new, much lower resolution photo. It yields ~250KB square photos and ~100KB panos on my iPhone 6.

This works, but it’s terrible

  • The screenshots are PNGs. PNG is a terrible format for photographs.
  • It leaves behind a couple 3MB intermediate images.

But hopefully it gets you out of a pinch!
