Define compress.
I assume same as Blighty that you want a smaller file size and that depends on image format.
Exported as PNG, lossless compression and already maxed out.
Exported as JPG, lossy compression and a default value of 90.
Both described here: https://docs.gimp.org/en/gimp-images-out.html
But then you can make the image size (in pixels) smaller, which you could say is a form of compression.
Sometimes both are combined to get an image down to a specified file size and there are plugins to assist.
Save-for-Web is one http://registry.gimp.org/node/33
