Re: [Gimp-user] How to reduce image file size while retaining width/height of image?

["Dora Smith" <villandra gmail com>]

With jpeg, you can change the amount of compression, and you are likely to 
be fine with the image quality.

You can also change the resolution - the pixels per inch.   72 is typical 
for the internet; 200 for printing, higher quality for historical quality 
images.  Some display/ formats will also change their physical size.

I'm not sure if gif offers compression or not.

You can export the file to a lossy file format such as JPG (
https://en.wikipedia.org/wiki/JPEG).  GIMP has an option to "Show preview
in image window", which will also give you an estimate of the file size
from the parameters.  You can modify the "Quality" slider until you reach a
desired file size.  Does this help with what you wanted to achieve?
