To add my 2 cents,
You can do conversions of this nature in code using the pygame
image.convert and/or image.convert_alpha classes

Hello all,
This is very likely a simple fix:
When loading textures and superimposing them atop other stimuli, I
often get
visual artifacts around the edges of the texture, likely due to OpenGL
texture manipulations. I have included a jpeg image of a screen capture
with one such texture artifact (in this case, the top and right edges
are
shown as grey bars, where the texture meets the background).
I had a problem with this too. I was using transparency in .png files
but not loading the texture data as gl.GL_RGBA. As soon as I changed
the texture format it all went away.
