[QUOTE="Rexer John, post: 144743, member: 12691"] You can't get more information out of a file than it already contains. What you can do is sharpen or soften. The image may look to be better than before and different image formats may look slightly different because of compression algorithms but you didn't release any extra information no matter how large the file size is. On the other hand, an image may look pixelated when it's enlarged. If you resample the image to larger size (number of pixels) you can blend the extra information into the image for a much better final image. You still didn't get more information out of the original file but you added "smart pixels" in between the originals. A BMP file saves each pixel as an individual unit of information so the file is huge. A Jpeg looks for areas of similar pixels and encodes the picture to get a much smaller file size. You get to chose how much compression you want, more compression = a more blocky image. If you start with a compressed jpeg image and then turn it into a bitmap resulting in a better image, the better image most likely comes down to a blending of the original jpeg image, removing artifacts prior to the image save.
