How to reduce image size on mobile

Forms often ask for a photo under a specific size like 20 KB or 100 KB. You can hit that exactly on your phone, without any app.

Steps

  1. Open the Compress Image to KB tool in your mobile browser.
  2. Tap to add your photo.
  3. Choose the target size (20 KB, 50 KB, 100 KB…) or a custom value.
  4. Tap Process and download the smaller photo.

Tips

Pick the largest size the form allows for the best quality. It works the same on Android and iPhone, and your photo stays on your device.
