If you look closely , it has white borders all over (see here). Now my question is , is there any software (free) that can help me crop out the circular area of the button.

I have: Windows 7 with GIMP (though I can't find such feature in GIMP) and Paint (same again)

Yes, there are lots. You could use the eclipse tool of a paint program to highlight the area you want to keep, inverse and the delete the selection. –  Dave Sep 6 '13 at 10:30

You could use Paint.Net.

  1. Open your image or copy it into a new image.

    enter image description here

  2. Pick the ellipse selection tool.

    enter image description here

  3. Place the cursor on the edge of the circle in the image:

    enter image description here

  4. Press and hold Shift and Alt and drag the cursor to the opposite side of the circle.

    enter image description here

Depending on what you want to do, you might actually want to select everything but the circle. For that you can use the Invert selection.

enter image description here

To use it, first select everything by pressing Ctrl+A and then performing the selection process as described above, in the Invert selection mode. Then you'll have everything but the circle selected.

If you then press Del, you end up with a clean button image:

I'd personally prefer the magic wand tool here. Let me throw together an answer using that instead –  Journeyman Geek Sep 6 '13 at 10:36
    
@JourneymanGeek: Magic wand doesn't produce a good result IMHO –  Oliver Salzburg Sep 6 '13 at 10:38

I prefer the magic wand - the trick being to lower the tolerance as low as possible to get a good result - I've used 10% but you can go as low as 1

As a side note to this answer, it always seems (to me anyway) that a tolerance of 27% is the sweet spot for most images –  TheTurkey Sep 6 '13 at 12:24
    
I tend to start low, and work my way up. Thats probably the case, I just lowered it from 50 to some suitably low number, saw it was good enough and left it there. –  Journeyman Geek Sep 6 '13 at 12:27
    
Nice. Will definitely try editing this way also. –  Gaurang Tandon Sep 7 '13 at 4:34

Well, you certainly can do it on GIMP. There's an ellipse tool as well:

enter image description here

It's very similar in selecting to paint.net, but you can also change the area of the selection after selecting it the first time --maybe to make fine adjustments-- by clicking and dragging your mouse over the squares appearing when you hover your mouse over the vertices or rectangles when it's over the edges of the square guide:

enter image description here

And zoom in if necessary:

enter image description here

After that, you can hit Ctrl+I (Invert selection or do "Select" > "Invert Selection" from the menubar to select everything outside the ellipse, then press Delete to remove the unneeded part:

enter image description here

The checked grey pattern indicates that these parts are transparent. If you don't see this, go to "Layer" > "Transparency" > "Add Alpha Channel" and press delete again without deselecting the current selection.

Now your image is ready to be exported as png :)

Thanks for your answer. Never knew this can be done in GIMP also :) –  Gaurang Tandon Sep 7 '13 at 4:33
