I am new to GIMP and have one problem with it. When i save the photos the files get unusually bigger. Here is a before and after example - i didn't edit anything on this picture.

Before (file size 152 KiB):

After (file size 441,2 KiB)

It is probably some preferences issue, but what?
I have tried searching the forum, search engines and reading tutorials without finding anything on what causes this, or how to fix it. Hope someone can help me with this.

did you do save or save as ?
if you change the file type...yes...the size will change
or when you save ... did you change the quality ?

no, i chose "save" . i tried it once again with another picture, and this time reset the "load defaults" and "save defaults", and the file size still changed alot. also i looked at the "advenced options" and the box named "use quality settings from original image" is checked, and when hovering my mouse pointer above it, it says that should "get almost the same quality and file size". Both images were originally jpeg, and i didnt change that either, nor the quality.

Initially when you 'Save' a .jpg it'll ask you about the compression options; this'll upsize or downsize the file that you're writing.
Subsequent 'Save' operations will use the compression factor that you set up.

You can click 'Save As', and the 3rd pop up (after file naming / confirmation) will be the compression options again.

Likewise, .png has a compression setting; that's where your larger file size is coming from. For some reason, the compression options didn't come up when I hit 'Save' for the .png, but it did come up when I hit 'Save As'.
