Paint.net Image Compression Issue

[nCo2K15]

Just trying to inject a texture into a 000C.pac but I can't seem to get the image to the same size. The original is 1.32mb and mine is 1.33mb, however I've got the settings the same as this topic: http://smacktalks.org/forums/index.php/topic/40680-texture-editing-guide-for-beginners/

Is it just paint.net? I've even tried all of the combinations of settings and checked that the image is the same size and resolution. I can't figure this one out; any help?

Don't use Paint.net. Photoshop is the way to go with this stuff.

 

The proper .dds settings for the color.dds are DXT1 with no alpha and four MipMaps.
