<p>WP Strip Image Metadata is a privacy focused WordPress plugin that helps in removing potentially sensitive metadata from your uploaded images.</p>
<p>What is image metadata?</p>
<p>Image metadata is extra information embedded in image files. This information is stored in a variety of formats and contains items like the model of the camera that took a photo.</p>
<p>However, image metadata may also contain identifying information such as the GPS location coordinates of an image taken with a smartphone for example.</p>
<p>This plugin provides an easy enabled/disabled setting so you can make the call on when image metadata should be removed.</p>
<p>Note: this plugin requires the “Imagick” or “Gmagick” PHP extension to function.</p>


WP Strip Image Metadata

Excellent plugin, simple and to the point. Confirmed it works perfectly via the "Edit more details" link when viewing an image in the media gallery.

Great plugin

Strip image metadata on upload or via bulk action, and view image EXIF data.
