You must make sure the image is in RGB mode (the titlebar should
indicate this). If it's not the menu item "Image/Mode/RGB" . Next you
must make sure that the background layer has an alpha channel, if it
hasn't you can add one with the menu item "Layer/Transparency/Add
alpha channel".

[Gimp-user] PNG and transparency

[Johannes Reese]

Hi all,

what determines if pressing the wipe-out button or pressing CTRL-x 
extinguishes to either the background color or to transparency? I thought the 
type of file would. But some png-files I opened behaved so that CTRL-x of a 
selected area makes the deleted stuff transparent (which I want), while with 
others all I can reach is substituting the selected area by the background 
color. How can I force those files to delete to transparency?

Regards,

Johannes
