To reverse the selection, choose Invert Selection from the Edit menu.

Everything but your image’s shape should be selected. Step 7: To fix this, select Instant Alpha from the selection tools and use it until everything but your image takes a red tint, then release the cursor. Your image should now be “clean”, except that it still belongs to the rest of the “frame”. Once you are done with each, hit the Delete key again in order to remove them from your image. Use it to draw a selection around all the objects that remain in your image making sure to completely close the selections. Step 6: Click on the Selection Tools icon again, but this time choose the Lasso Selection instead. You will see that a few images and most of the background are gone by now. Step 5: With the shapes selected, press Delete and click on Convert if the dialog box pops-up. You will see all these shapes (including the one you want to extract) have been selected. Don’t worry about that and release the cursor. In most cases, you might see that not only the shape you want to extract but also other shapes in your image don’t become red in color.

Keep doing so until everything in the image takes this red tone EXCEPT for the shape you want to extract.

You will see that the image starts to become “reddish” at some areas depending on how you move the cursor over it. Step 4: Now press and hold on the mouse and start moving the cursor along the image. From the available tools go to the Selection Tools (the dotted rectangle icon), click on it and then select Instant Alpha. Step 3: On the top bar of Preview, click on the pencil icon to reveal the Edit Toolbar. To extract it though, we’ll first have to remove the background and the text in the image. Step 2: Choose the object you want to “extract” from the image. If Preview is not set as your default to open images, you can find the application in the Applications folder. Step 1: Pick your image and open it on Preview. You want to learn how to do it? Just follow the steps below. However, Preview also comes with a quite decent set of editing tools that can take care of a few complex tasks, including extracting shapes, just like with Photoshop except in a far easier way. Thankfully, every Mac comes with Preview, a very simple, yet powerful application that (sadly) most Mac owners only use to view images and PDF files.
