When taking a photo of a crowd, be careful what you do with it. Some people appearing in this photo may not want to see this shared on the internet. A good way to prevent yourself from this kind of problem is to blur faces in a photo, several free tools allow you to do this.
If you take a photo during an event, concert, or any other popular event, there is a good chance that faces will appear in it. You want to share this snapshot on the internet except that by doing so you are putting the privacy of these people at risk.
Some individuals do not want their presence at a demonstration, for example, to be known. To avoid any legal problem, the easiest way is to blur those famous faces. We have selected for you two tools allowing you to do this directly from your browser or your smartphone and for free: Facepixelizer, Image Scrubbler and Signal.
Facepixelizer, the most efficient, but only on computer
Facepixelizer is a free tool available on any web browser. Its ease of use is its strength and it even offers an automatic face detection system.
Start by going to their website and drag and drop the photo whose faces you want to blur. Wait for the photo to open on the site and we can start the heavy lifting.
As explained previously, Facepixelizer offers an automatic face detection system. Although it is not completely at the top and it can miss a few faces instantly, it allows you to do a first sorting and blur some elements before letting you do the rest manually. To activate it, click Pixelize, Blur, ou GF in the category Face Detection. The first option will rasterize, the second will blur and the third will add little Guy Fawkes masks in V for Vendetta.
When the automatic face detection has done part of the job, complete it by clicking on Manual in Selection Effect. Draw a rectangle around the face to be blurred and do this for all the elements that are still visible.
Finally, save the image and you can share it without endangering the privacy of others!
Image Scrubber, compatible on smartphone and offline
Image Scrubber focuses on the essentials and is not going to offer a very sophisticated and elaborate interface. But thanks to this, the site works on computer, smartphone and even offline.
To start, open your photo by clicking on Open image at the top left of the interface and wait for it to appear.
In the taskbar, choose between Paint and Blur to hide a face and then click on the areas to blur.
Then adjust the blur rate in Blur radius and the size of your "selection brush" in Brush size. When you have set these parameters to your liking, all you have to do is blur all the faces and you're done.
The result is a little more "messy" than with Face Pixelize, but it can work 100% offline. On a computer, download the .zip file available on the home page of the site, unzip it and open the file index.html. On a smartphone, you will have to open the page using the internet network and then you can cut your network when it is done.
