You don't HAVE to shit up the web with more JPGs converted to PNGs like Donald Trump you know. At the very least you could do us all a huge favor waifu2x the JPG before converting it to a PNG. You no longer have to be a 1337 hax0r to do this, there's tard friendly websites where you just upload the JPG and download the clean PNG.
