We were researching free tools available online for obscuring and anonymising the face of specific pupils in group shots, prior to uploading onto school websites, in the interests of privacy, child protection and safeguarding.
We came across an excellent free tool that you may or not be aware of that it very straightforward to use. It produces a more subtle result than painting over the Child’s face. It is available at Face Pixelizer and explained in a video here.
The pixel effect is best for faces and the blur tool is useful for obscuring text in documents. Even though Facepixelizer runs in the browser, your images are secure because they never leave your browser and are never sent out beyond your network. All the processing happens in your browser.
