I've installed Gimp to do a very simple pixelated effect on images. Now, it IS satisfying in the Gimp interface, but whenever I export it to PNG, I get an ugly faux-pixel result. Any idea where this could be coming from? (It should be noted that I am a total neophyte in graphic design.)
The pixel effect was done by selecting the layer and then going into Filters > Blur > Pixelation. I have taken the original image from a random website and just copy-pasted the logo in a separate file, then applied the filter.
