Removing the alpha channel

Recommended Posts

This may be a silly question but I'm new to Paint.net and have searched everywhere without finding an answer: How do I remove the alpha channel from a png file? I make textures for Second Life so simply setting transparency to 0% won't work, I need to remove the alpha completely. Right now I use Gimp to do that but I'd much rather do all my image editing in paint.net of course.

Load the file and save it again but select 24 bits in the options.

You will see in the preview that the image will be rendered against a white background.


If you need a different background color then

- add a layer in the expected color below of you image layer

- flatten the image

- save as png.
