For some weeks I am wondering why jpg files I save with Photoshop are extremly big like a 300 x 300 image is around 600 KB even when I reduce its quality all the way down to 0. Its all in RGB 8 Bit so thats not the problem is this a known bug? I am using Photoshop CS 5.5
Even when I create a blank white canvas its still more than 500 KB when saving as jpg
How can localize the problem better?
I uploaded the blank white image I created which is around 500 KB big could someone have a look at it?
