StripImage also delete ICC image profile by default.
The resulting images seem to lose a lot of color information and look "flat" compared to their non-stripped versions.

Consider keeping the ICC profile (which causes richer colors) while removing all other EXIF data:

1. Extract the ICC profile
2. Strip EXIF data and image profile
3. Add the ICC profile back

The code is:
<?php
$profiles
= $img->getImageProfiles("icc", true);

$img->stripImage();

if(!empty(
$profiles))
   
$img->profileImage("icc", $profiles['icc']);
?>

Please note that striping off the exif information without handling the orientation information available in the exif will lead to wrong orientation of the image

this will actually clear exif data so if you run an image uploading script with privacy concerns, this will effectively clear all GPS / metadata from the image.
