Export Help! New User

[Cm12]

Hi, I'm new to Gimp so excuse my (probably) simple problem. So I've made an Icon I want to export as just a circle. So I put my alien in the circle but when I export it, unknown why to me, the rest of it is back even though I deleted the rest of it. 

Thanks!

1. In what format did you export it? png supports transparency, jpg does not.

2. It may have a transparent background, but it depends on the viewer as to how transparency is displayed. Some use checked gray ; some use white ; some use black to display transparency.

3. Some websites convert images to jpg and remove transparency. Re-download you image and open it in Gimp to see if the transparency is still there.

..but where are you sending the icon to ? Some web site / game site / social-something-or-other ?

As Blighty explained all depends how the site displays transparency for png's. However there is another factor. The original pixels are not thrown away just covered by a mask. Some game sites in particular ignore the mask or require a specific colour. (usually black or white]

Example: (very like your first imgur screenshot) https://i.imgur.com/dt6BGxf.jpg
The circular cut-out is ok but if I use the eraser tool and anti-erase mode I can recover the 'cut' pixels.

To prevent that: https://i.imgur.com/RhdvDSW.jpg
Exporting as a png with de-select Save color values from transparent pixels

As a check: https://i.imgur.com/gbE9KSa.jpg
Open that new png and use anti-erase on it. Just a plain background, which is the alpha mask used by the display application to apply transparency.

Solved! Thanks for the help!
