: Is there a way to perfectly scale up an image, by a factor of a square number? What I mean is, if I double the length and width of an image, then I could take every pixel and make it
What I mean is, if I double the length and width of an image, then I could take every pixel and make it a 2x2 square, thus enlarging the image, but not losing any pixel data.
When I tried doing this in some image editing programs, it did the thing they always do, where it changes the colors of some pixels to make it all blend in. But I would like for it to perfectly scale it up.
Does anyone know of a software (preferably free) that could do this?

Perfect square, as said above, just makes it blocky,
If I understand correctly you simply need to reescale your image using "nearest neighbour", instead of bicubic or other algorithm.
If you have an image of 100x100px and you scale it up to 200x200 using nearest neighbour it will look the same as if you are using a 200% zoom.
