Edit Question
Title
Body
I'm going to let users upload images of 300x300 compressed with JPEG. Is there a way to determine what the maximum file size of such an image would be? I can imagine this can be tried by compressing random noise at 100 quality, but is there a theoretical maximum? Say that the image is totally uncompressable random noise, could it be 3 bytes per pixel (24-bits colour) and a margin for the metadata? Or could such an image turn out larger than the original when compressed?
