How to remove the background from an image

It has never been so easy to remove a background from an image. Since 2 days ago it's possible to do it on the web for free, via an app built on python, ruby & deep learning.

The website is remove.bg and contains an online tool to automatically remove the background of any image (with a person in it).

It's the designers' dream, saving time and money and being 100% automatically. The tool doesn't work 100% of the times, but is perfect for personal use, as it is free. It can be an alternative to Photoshop or Gimp.
