How to save a jpg file with the Gimp?

A tutorial on how to save an image, say it's something simple, just click, but you're really saving the most of your image?
Save a picture also means deciding on the format, the compression and quality.

Formats pills
* = gif is transparent, no nuances, average quality = slight (future tutorial)
* png = yes transparency, gradients, is heavy
* = jpg quality = no transparency, gradients, quality is average weight =

Let's see all the parameters for a rescue jpg.

1. File -> Save As


2. By clicking the "Save As" dialog box opens to save the image in your PC to write this: image. Jpg
(want information about this format for saving images? See here on wikipedia)
The program will ask you to "export" the image by clicking "yes", opens the following dialog box

This dialog box appears that gives us the opportunity to choose the quality (and therefore the level of compressine) if we aim the box "Show preview in image window" we can see real-time as our images will be simultaneously and gives us the size (ie the weight in kb) of the image.

and advanced options?
if we click on the little black arrow opens a further part of the dialog box with a choice: *

Optimization (click on quadrattino always conglomerate)

* Progressive (How about yes, it works if the image is displayed prograssivamente loaded, then COPRESS better)

* subsampling : choose the method (from the more compressed than less compressed, all this goes to affect the final weight image)

3. Click on "Save" at the end of the window and you're done!
