Hide faces in your images by telling Cloudinary to either blur or automatically pixelate the detected faces. This is done by setting the effect parameter to either blur_faces or pixelate_faces (e_blur_faces or e_pixelate_faces in URLs). The level of blurring and the size of the pixel squares can customized.

Here's an image example uploaded to Cloudinary:

###Blurring faces Blur all detected faces of the image by setting the effect parameter to blur_faces (e_blur_faces in URLs):

While the default blurring value is 100, you can customize the level to a value between 1 and 2000 (the higher the value - the more blurry the effect).
For instance, here's a more blurry example with a value of 1000:

###Pixelating faces Pixelate all detected faces in the image by setting the effect parameter to pixelate_faces (e_pixelate_faces in URLs):

You can also set a custom value for the size of the pixels squares. Here's an example of larger squares:

Here's an example of smaller squares:
