:A JPG file is inherently compressed (think like a very low quality YouTube video) and as such it is practically impossible to remove the artifacts of JPG compression from the image. "Converting" it is pretty much to same as opening it in Paint as saving it as a different file type. --[[User:Abcboy|Abcboy]] ([[User talk:Abcboy|talk]]) 22:59, 12 August 2015 (UTC) | :A JPG file is inherently compressed (think like a very low quality YouTube video) and as such it is practically impossible to remove the artifacts of JPG compression from the image.

:::PNG is preferred over JPG because JPG is lossy (if you open a JPG, edit it and save it as a JPG, and repeat, the quality will steadily get worse unless your program is really smart, in which case it will get worse slowly, but they still suffer from the coefficient division and the 8 by 8 blockiness. JPG also doesn't support transparency. The only thing that should be in JPG format are scans of Trading Cards and some photographs. (because scanners are terrible?) | |||
:::PNG is preferred over GIF because GIF has a 256-color limit, which leads to dithering. Additionally, it doesn't support partial transparency. | |||
:::(GIFs and JPGs can be saved as PNGs, but still have other qualities of the original file format.) | |||
:::If you want to know more, just search up "image file type comparison" and you'll probably find something with more information than I have to offer. To see the difference for yourself, try converting one of the 1280x1280 Ken Sugimori Pokémon artwork and saving it as a GIF and JPG, and compare them side by side. --[[User:Abcboy|Abcboy]] ([[User talk:Abcboy|talk]]) 23:32, 12 August 2015 (UTC) | |||
