Create transparent background images easily on Mac [Trick]

      I acknowledge my ineptitude for image editing; I haven't learned more than a few things yet and almost all based on applying preset filters. Sometimes i need transparent background images to combine with others or insert into documents so I had to resort to searching for them like this on the internet, a search that most of the time was unsuccessful.

      Yesterday I discovered a little trick, or rather one of those half-hidden functions in Mac, to remove the fondo (or certain color) of an image from Preview thus leaving it transparent.

The process is very simple, like almost everything in Mac:

1. We open the image with Preview
2. Next, we click on the "Show editing toolbar" icon and then, on that bar, we click on the "Instant Alpha" icon, as shown in the following image. The pointer then turns into a cross.
   

   Two easy steps in Preview

3. With the mouse, we position ourselves on the bottom of the image that we want to erase to make it transparent, we click with the left button and drag to the right. We will see that that background or color turns to another color and is surrounded by an intermittent line when we release the mouse, that means that it will be erased and will remain transparent.
4. We release "click" when we have already selected the area of ​​the image to be deleted, we press the Delete key on our keyboard and save changes.

 And that's it, we already have our image with transparent background for whatever we want, and without having to learn Photoshop.

 I hope you find this advice useful. Greetings and until the next post.
