title: resize image without losing quality with Gimp
body: <p>i have a bunch of images which are way too big i need to decrease their size from 30 kb to 10 or 5 kb without loosing quality. I tried to change the dpi and pixels with no succeed. The images got blurred, and as they have text i can't read anything after the changes. Is there anyway i can accomplish this without loosing quality? I have almost a dozen images in my application.</p>
  
  <p>Thanks in advance and have a nice day.</p>
