Photoshop Illustrator graphic help!

[Crew]

So i have a logo i need to remove edges from, to make it rounded, the design is rounded but the picture still comes out square with white spacing at the corners, say i needed to get it printed on a tee shirt and i only need to design section not small spacing on the corners. 

 

The green in this picture displays what needs to be removed. in photoshop it is a transparent backgound but when saved as a .jpeg it makes it white.

 

From What ive read it sounds like it needs to be converted to a vector image in illustrator but i dont know what im doing in illustrator. Any help would be great! 

In the picture you can kinda see the edges are rounded, thats how i need to image to be. the white area where the green is should be transparent.

Save the picture as .Png(for basic transparency), or .SVG(if you need vector) .JPG doesn't support transparency, or any other alpha channels I believe.

 

For .PNG: Go to: File--> Export...--> then in the dropdown box .PNG(*.PNG)

 

For vector: Go to: File--> Save as--> and in the drop down menu "SVG(*.SVG).

Did you enable transparency?

Also, keep in mind that some picture viewers don't display transparency.
